AI & Full-Stack Developer (5+ yrs) building web, mobile & AI SaaS products across healthcare, fintech, legal & eCommerce. 250K+ users served, 1M+ transactions processed React, Node, Python, AWS, LLM
Your product launches on the agreed date, or you pay $0 for that milestone.
Why can I make that commitment?
✅ Sr. AI & Full-Stack developer with 5+ years building scalable web, mobile, and AI products.
✅ A track record across healthcare, legal, fintech, and eCommerce.
✅ Built solutions serving 250K+ users and processing 1M+ transactions.
✅ Focused on choosing the right technology to ship faster.
Here's what most founders learn too late.
You don't have a development problem. You have a "we built the wrong thing" problem.
My job is killing that mistake before it costs you anything. I move 3x faster because I'm not reinventing the foundation every time. Every hour saved goes straight into the parts of your product people will actually pay for.
Think of me as a technical co-founder without the equity conversation. Someone who has already made the mistakes you're about to make.

Most developers write code. I help startup founders build products they can actually launch, grow, and show to investors.
I have shipped 15+ products for international clients across the US and Europe, including Ambiently (real-time Flutter and Supabase MVP, live on TestFlight in 6 weeks), Hayakom (cross-platform tourist booking app), and JobDriver ai (AI SaaS platform with OpenAI, Stripe, and user dashboards). My fastest MVP went from brief to TestFlight in under 6 weeks. I maintain a 100% Job Success Score because I treat every project as a long-term partnership, not a one-time task.
If you have been burned by developers who disappear mid-project, deliver sloppy code, or go quiet when things get complicated, that is exactly what I have built my reputation against.

Milestone-based with clear deliverables from day one. Single point of contact throughout. Regular progress updates without chasing. I use Claude Code and Cursor as part of my daily development workflow, which means faster prototyping, earlier bug detection, and more shipped in less time without inflated timelines.

— I enjoy working with founders, product owners, and engineering teams who care about building products the right way, not just shipping the fastest possible version.
— Whether I'm joining at the MVP stage or improving an existing production application, my goal is always the same:
+ Build clean, maintainable architecture.
+ Reduce future technical debt.
+ Simplify complex business workflows.
+ Deliver a product that's easier to scale, support, and improve over time.
— If you're looking for someone who completes development tasks, there are plenty of good developers available.
— If you're looking for someone who thinks about your product, challenges technical decisions when necessary, and engineers solutions that support your business long after launch, I'd be happy to discuss your project.
