I do fixed-cost, goal-oriented projects only. No hourly billing. You need results, I need clear goals. We talk, agree what matters most, split it into steps, review weekly. Two kinds of work. Either you have an idea and nothing built yet, and I build the first real working version and get it live, usually in two to six weeks. Or you already have something half finished, slow or broken, often AI-generated, and I find out what is wrong and get it working properly without shutting your business down. ** How we can work together (fixed rate) ** Architecture audit and tech roadmap: from $1,500. I review what you have, or plan what you want to build, and give you a clear written plan. Ready-to-launch MVP: from $6,000. I take your idea and build a working product ready for your first users or investors. ** A few results ** Built the first version of the backend for a trading marketplace that now moves about 1.5 billion dollars a year. Seven years later the CTO asked me back to help it scale. Built a sales tool together with its CEO that went from zero to 40,000 dollars a month within three months of launch. Built a tool for doctors that handles patient health records under HIPAA rules, on my own, start to finish: servers, admin area, email automation, and the sites doctors and patients use. Co-founded a software marketplace worth 20 million dollars at its peak and ran the technical side. Fifth engineer at a hosting company that grew to 15 million users. ** What I build ** Software products, internal tools that replace slow manual work, and iOS and Android apps with React Native. Recent work spans healthcare, education, online stores, and US sports pool apps like pick em and squares. ** Stack ** Full stack TypeScript: Node.js, React, Next.js, React Native. PostgreSQL, MongoDB, Redis. AWS hands-on for 10+ years, from bare metal to Kubernetes and serverless. AI built into features (OpenAI, Claude, Gemini, custom agents, RAG) and into how I deliver, always with tests and guardrails so speed never costs quality. ** Experience ** Top 3% network at Toptal since 2016. 15+ years delivering for founders, from zero to companies running at billions per year. Master's degree in Physics. I keep communication clear and direct, and I ask the same of you. If you have something you want built, or something built badly you want fixed, send me a message and tell me about it.
