Senior Full-Stack Engineer (Next.js / Supabase / AI / Stripe / Twilio) - Phased Build ($10k cap)
I hired Igor to build DearHim and honestly he exceeded what I thought was possible on the timeline we had. It’s not a simple app — web plus iOS, payments, auth, AI, SMS, streaming chat, the whole production setup — and he handled all of it, backend to deployment.
What I appreciated most is that he actually cares. He doesn’t just close tickets, he thinks about whether something’s actually right, and he’ll find the better solution instead of the quick one. Launch week got hectic, as these things do, and he stayed calm and just kept knocking things out until we were live.
I’m already building two more projects with him, which probably tells you everything. If you need someone who’ll take real ownership of something complicated, hire Igor. You won’t regret it.

Build a desktop app for Static.app to sync website files using Flutter.
Absolutely — here’s a warmer, more human version with a natural tone:

Working with Igor was honestly a fantastic experience. Not only did he deliver everything *ahead of schedule*, but he also went the extra mile and did even more than what we initially asked for — and it was all done with great attention to detail.
He’s super communicative, easy to work with, and clearly takes a lot of pride in what he does. You don’t often come across someone this reliable and proactive. It felt like he

Founders and CTOs don't call me first. They call after the offshore agency delivered a half-working prototype. After the generalist ran out of depth. When the stakes are too high to get it wrong again — that's when they call me.
I work like a technical co-founder: I understand your business problem as clearly as the technical one. No account-manager layer, no junior handoff. You work directly with senior engineering across architecture, implementation, deployment, and the post-launch fixes that real systems always need.
Over 70% of clients come back for another engagement — because trust is easier to earn through delivery than through proposals.
📈 PRODUCTION RESULTS
✅ n8n + GPT-4 replaced a 12-person workflow — 10,000+ records/day at 99.2% accuracy, saving $380K/year. Shipped in 3 weeks.

✅ React + LangChain legal AI tool — cut attorney document review time by 73%.
✅ Next.js + Supabase multi-tenant SaaS with Stripe — zero to $45K MRR in 5 months.
✅ Cross-platform Flutter app — 50,000+ active users across iOS, Android, and desktop.
✅ OCR + GPT-4 + LangChain document pipeline for logistics — 8x throughput, same headcount.
✅ HIPAA-compliant clinical RAG system — delivered in 5 weeks.
✅ Loan-decision latency cut from 4.2s to 280ms for a Series-A lender.
✅ Author of ngx-mask — 2M+ monthly npm downloads, used in fintech, healthcare, and enterprise SaaS worldwide.
