I'm the developernon-technical founderspartner with to build
Have an app idea but don't know code? Stuck with a half-finished project? I help founders like you build and scale SaaS apps from $0 to $100K+ MRR.
Most of my clients work with me for years. Some for over a decade.
"Matthew's vision and code turned our site into the revenue engine that fueled 10 years of YoY growth."

You tried no-code tools. Then you hit the complexity ceiling.
You hired a developer. Then they disappeared.
You need custom software, but you're not technical.
That's where I come in — bridging the gap between founder vision and working product.
I'm not a contractor you manage. I'm a partner who understands your business and builds what it needs to grow.
I meet founders wherever they are
Whether you're starting from an idea, scaling an MVP, or rebuilding after turnover — I help you move forward with clarity and code.
💡 Idea → MVP
Discovery Sprint: $5,000 (1-2 weeks) MVP Build: $15,000–25,000 (6-8 weeks) Start with a Discovery Sprint to map requirements, validate technical approach, and get an accurate build estimate. You keep all documentation even if we don't proceed.
You validated your idea. Now you need it built right. Not a prototype. A real product ready for paying customers. Built in 6–8 weeks with a foundation that scales to $100K+ MRR.
🚀 MVP → Scale
Discovery Sprint: $5,000 (1-2 weeks) Ongoing Partnership: Starting at $5,000/month Start with a technical audit to identify bottlenecks and prioritize what to build next. Then continue with ongoing development and strategic guidance.
You have customers and revenue—now you need to scale. Your product works, but technical debt is slowing you down. You need someone who can build features AND make technical decisions.
🔧 Established → Stability
Discovery Sprint: $5,000 (1-2 weeks) Stabilization + Ongoing: $5,000–7,000/month Emergency codebase audit within 48 hours. Stabilize first, then build with confidence. Most takeover clients stay for years.
Your developer left. Your customers didn't. I step in immediately, audit your codebase, stabilize, and keep building.

Schedule a CallThe difference between code that works and code that scales
Every SaaS company hits the same inflection points: when your database slows down, when your architecture can't handle new features, when technical debt starts costing you real money.
I've seen these problems before—and I know how to avoid them.
What scales now will still scale when AI-generated traffic is 10×.
Architecture for Tomorrow
Build systems that handle 10x growth without a complete rewrite.
Microservices, event-driven patterns, and database sharding strategies that scale naturally with your user base.
Optimize for Change
Structure code so new features ship faster, not slower, over time.
Component-driven development, API-first design, and modular architecture that accelerates rather than constrains development velocity.
Security from Day One
Handle user data like it matters, because eventually it really will.
Zero-trust architecture, encryption at rest and in transit, audit logging, and compliance frameworks built in from the start.
Built to handle tomorrow's challenges today
The next wave isn't just AI tools—it's autonomous agents generating 10x traffic, making 1000x API calls, and stress-testing every architectural decision you make today.

Four ways to work together
From short-term planning to long-term partnerships. All projects start with a Discovery Sprint to ensure we're building the right thing.
Project-Based Work
Discovery, MVP builds, and platform rebuilds — scoped engagements with clear deliverables.
Discovery Sprint
Before any code is written, we map out exactly what needs to be built and why
This is paid work, not a free consultation. The deliverables are yours to keep—you can hand them to any development team and they'll know exactly what to build.
- Technical requirements document
- Architecture & stack recommendations
- Risk assessment and mitigation plan
Validation MVP
Built to test your concept with real users
Core functionality to prove your hypothesis. Clean, working product for beta testing with a foundation that CAN scale (but optimized for speed).
- Core functionality for testing
- Clean, working beta product
- 30 days post-launch support
Growth-Ready Product
Built to handle paying customers from day one
Production-ready architecture that scales to 1,000+ users. Built to iterate on, not rebuild.
- Production-ready from launch
- Scales to 1,000+ users
- Payment integration + security optimization
Platform Build / Rebuild
For established businesses that need to scale or rebuild their core platform
Complete platform redesign or rebuild from scratch with integrations, technical debt elimination, and long-term scalability.

- Integration with existing tools
- Technical debt elimination
Ongoing Partnership
Long-term technical partnership for founders who need continuous feature development and strategic guidance.
Standard Partnership
Long-term technical partner, not a contractor
This isn't staff augmentation—it's partnership. I learn your business, understand your customers, and help you make technical decisions that drive revenue.
- 10-15 hours/week of focused work
- 2-3 feature releases per month
- Response time: within 24 hours
Priority Partnership
Dedicated technical leadership with priority access
Think of me as your Fractional CTO—but hands-on. I design, code, and ship.
- 15-20 hours/week
- 4-6 feature releases per month
- Response time: within 4 hours
How I Work
Every project follows the same proven process:
Discovery Sprint (1-2 weeks)
Map requirements, plan architecture, estimate timeline. You get complete documentation whether we work together or not.
Build in Focused Sprints (4-20 weeks depending on scope)
Weekly check-ins to review progress. You see working features constantly, not after months of silence. AI-assisted development accelerates standard patterns.
Launch & Support (30-60 days)
Deployment, monitoring, bug fixes. I don't disappear after launch.
Ongoing Partnership (optional)
Most clients continue working with me long-term. Continuous iteration as your business evolves.
Technology I Use
Frontend
Next.js, React, TypeScript, TailwindCSS
Backend
Node.js, Supabase, PostgreSQL
Payments
Stripe
Hosting
Vercel, AWS
Tools
AI-assisted development (Claude, Cursor) for velocity without chaos
I choose proven, modern technologies that scale—not whatever's trendy this month.
Who I Work With
I take on 3-4 new partnerships per year. I'm selective because I work closely with each client and often continue for years.
Good fit:
- ✓Non-technical founders who need custom software
- ✓Founders who've outgrown off-the-shelf tools (Shopify, WordPress, no-code)
- ✓Companies with revenue who need to scale or rebuild
- ✓Founders whose previous developer disappeared
Not a good fit:
- ✗Projects requiring a full development team (I'm a solo partner)
- ✗Agencies looking for white-label work
- ✗Projects with unrealistic timelines or budgets
Pause or cancel anytime.
Frequently Asked Questions
Why paid Discovery?
To avoid $50k mistakes. You get scope clarity, technical validation, and a plan you can use even if you don't hire me. Free consultations create bad incentives—I'd tell you what you want to hear instead of what you need to hear.
What makes this a partnership?
I own the roadmap with you, not just tickets. I'll say "don't build that yet" as often as "ship this now." I make strategic technical decisions, not just implement yours.
Do I own the code?
Yes. You own the repos, infrastructure, and all accounts from day one.
What if I need changes after launch?
That's what the ongoing partnership is for. Most clients continue working with me because building software is never truly "done."
How do you use AI?
AI (Claude, Cursor) accelerates the 90% of code that's standard patterns—auth, databases, forms. This lets me focus on the 10% unique to your business. You get traditional quality at faster timelines.

Frequently Asked Questions
Common questions about working together, contracts, and technical processes.
Kickoff in 1–2 weeks. I slot into—or lead—your current team from day one. Initial planning calls happen within 48 hours of agreement, with active development starting in the first sprint cycle.
I help you hire and onboard your internal team when ready. You keep all code and architectural knowledge. I can assist with technical interviews, architecture reviews, and knowledge transfer to ensure smooth transition.
You own 100% of custom code and business logic. I retain rights to reusable components and general methodologies. All work is delivered with complete source code, documentation, and deployment instructions.
Next.js, React, TypeScript, Node.js, PostgreSQL—whatever makes sense for your use case. I focus on proven, maintainable technologies rather than bleeding-edge frameworks that might create technical debt.
Every line is reviewed, tested, and documented following industry best practices. Automated testing, CI/CD pipelines, code reviews, and documentation are built into the development process from day one.
Weekly development cycles with daily progress updates via Slack or your preferred platform. You see exactly what's being built and why, with time for feedback before it's too late to change direction.
Emergency support is included in Core and Plus tiers with appropriate SLA response times. Caretaker tier includes basic emergency support. All tiers include proactive monitoring and issue prevention.
30-day out clause – zero risk.
Month-to-month contracts with 30-day notice. No long-term commitments required. Project-based work (like Refined MVP) has milestone-based payment schedules with clear deliverables and timelines.
Many businesses outgrow Shopify's checkout limitations, product variant restrictions, or lack of custom business logic. I've helped founders migrate from Shopify to custom platforms when they need: Complex pricing rules Shopify can't handle, Custom checkout flows for B2B or wholesale, Integration with manufacturing or fulfillment systems, Product configurators that exceed Shopify's capabilities. We can keep Shopify for content and add custom functionality, or build a complete replacement. Schedule a discovery call to discuss your specific limitations.
Yes. I regularly help founders move from WordPress to custom Next.js applications when they hit WordPress's performance ceiling or need functionality that's impossible with plugins. Common reasons to migrate: Performance issues with high traffic or complex queries, Need for custom user dashboards or workflows, Security concerns with plugin dependencies, Costs of maintaining complex WordPress infrastructure. We can migrate content, preserve SEO, and build features that would require dozens of plugins in WordPress. Most WordPress-to-custom migrations take 8-12 weeks.
Absolutely. No-code tools are excellent for validation, but many businesses hit hard limits around: Bubble: Performance degradation beyond ~1,000 users, complex workflow limitations; Webflow: Database size restrictions, lack of custom business logic; Airtable: Not built for customer-facing applications, API rate limits. I help founders migrate from no-code to custom code when the business has validated product-market fit but needs more control, performance, or complex features. You keep what works, rebuild what doesn't.
Many successful businesses start by using generic SaaS tools (CRMs, project management, booking systems) but eventually need custom solutions that match their exact processes. I build custom alternatives when: You're paying $500+/month for features you don't need, The tool doesn't integrate with your systems, You need workflows the tool can't support, Data ownership or privacy requirements demand self-hosting. I'll help you analyze whether building custom makes business sense. Often it's cheaper to build exactly what you need than to keep paying for 80% unused features.
Yes, this is one of the most common scenarios. My process: 48-hour codebase audit — Understand what exists, what works, what's broken; Immediate stabilization — Fix critical issues, restore functionality; Technical debt assessment — Identify what needs rebuilding vs. what can stay; Roadmap planning — Prioritize fixes, features, and long-term improvements. Most founders who come to me after developer turnover stay for years because they never want to be in that situation again. I document everything, keep code clean, and ensure you're never dependent on me.
Ready to Build Something Better?
Most founders I work with tried the DIY route, hired (and lost) a developer, or hit the limits of their current tools.
The next step is a free 30-minute call where we'll discuss:
- •What you're building and why current solutions don't work
- •Whether custom software makes sense for your stage
- •Rough timeline and investment required
- •If we're a good fit to work together
No sales pitch. Just honest technical guidance.
