Evgeny R.

I build software that outlives the reason it was written. One product my team and I helped build from day one is now a company valued at $850M. The less flashy proof is that clients keep me: several engagements have run two and three years, and most clients come back. I'm a senior full-stack and AI developer and the founder of Emphasoft. 189 projects, 25,900+ hours and $1M+ delivered on Upwork, at 100% Job Success. Clients often come to me after someone else has already failed. One had gone through a freelancer and two agencies before we finished the platform. Another wrote that we completed a project where others could not. That's the work I'm best at. There are two ways people work with me. I build it. You have an idea, or a product that needs a new capability. I own architecture and delivery, my senior team builds it, and you deal with one person the whole way through. I augment your team. You have a product and not enough engineers. I give you a senior developer, or a small team, working full-time inside your codebase, from people already on my bench, usually starting within days. They stay: my longest engagements have run over three years with the same engineers on the same product. Onboarding, continuity and technical direction are my problem, not yours. Either way, I'm accountable for the outcome. What I build: ✅ MVPs and new products — built to scale, not to be rewritten ✅ SaaS platforms and complex web applications ✅ API development and third-party integrations ✅ Dedicated engineers and teams, full-time, long-term ✅ AI features inside products that already exist ✅ Mobile apps (Flutter, React Native, iOS, Android) AI work I deliver: ✅ AI agents and agentic workflows ✅ Workflow automation — n8n, API orchestration, internal tooling ✅ Support bots trained on your own data, answering in your team's voice ✅ Document and invoice processing at scale — OCR and LLM extraction ✅ LLM integration into existing platforms — Claude, OpenAI, self-hosted models Stack: ✅ Back-end: Python (Django, FastAPI, Flask), Node.js ✅ Front-end: React, Next.js, TypeScript ✅ Infrastructure: Amazon Web Services (AWS), DevOps, PostgreSQL, Supabase ✅ Mobile: Flutter, React Native, Capacitor.js Not a fit for: one-off fixes in legacy code, crypto projects, or work where the deciding factor is the lowest hourly rate. Tell me what you're building and where it's stuck.
