I've shipped production systems that serve 20M+ users, generated $1.5M ARR, and helped a startup raise $7.4M — all using the same AI-augmented engineering approach that makes my team 3–5x faster than traditional agencies. I work with funded startups and growing companies that need senior technical leadership and fast execution — not just a developer for hire. ───────────────────────────── WHAT I ACTUALLY DELIVER ───────────────────────────── AI Systems in Production Custom AI agents, MCP integrations, RAG pipelines, multi-agent orchestration. Not demos — live systems handling real workloads. Built with Claude, LangGraph, FastAPI, Python. Example: MCA underwriting engine that replaced manual analyst review for a financial company. CTO-as-a-Service Architecture review, tech roadmap, team assessment, technical debt audit. You get a clear PDF report and a prioritized action plan — not a slide deck. Packages from $250 (Express Audit) to $1,000 (CTO Day embedded with your team). Engineering Acceleration for Series A/B Your team is too small, hiring takes 6 months, investors are pushing. We bridge the gap: embedded AI-native team, weekly demos, fixed-scope milestones. You stay in control, we execute fast. Vibe Coding Rescue AI-generated codebase that doesn't hold up in production? I audit it, find the structural issues, and fix them. Saved multiple clients from expensive rewrites by catching architecture problems early. ───────────────────────────── PROOF — WHAT WE'VE SHIPPED ───────────────────────────── Stats.fm — 20M+ users worldwide. Flutter, multi-platform. I was Flutter Lead Developer. Production-stable across 6 build configurations. IRNBY Training Club — $1.5M ARR, 73k users, 207k orders. I was CTO for 3 years. Zero major outages. 5–8 person team delivering like 15–20. Rhino — Premium taxi app in São Paulo. Our Flutter MVP went from idea to investment pitch. Result: $7.4M raised. DevForge — AI orchestration platform. 6 agents working as a team. 26,000 lines of code. Built solo in 7 weeks with Claude Code. MCA underwriting AI. On-premise Ollama. Bank statement analysis. HFT Trading System — AI-powered decision engine for high-frequency trading. 50ms model inference latency. C++ core with custom inference pipeline. Built for sub-millisecond trading environments where model latency is a competitive edge. AnimaFest — Idea to production in 1 day. Not a prototype — a live SaaS platform with real users. ───────────────────────────── HOW I WORK ───────────────────────────── Fixed-price milestones. You know what you're getting, when, and what it costs. No hourly surprises. Every engagement starts with a scoped Discovery Sprint or Tech Audit — so we both understand the problem before committing to a solution. My team is small and senior. No juniors padding hours. No account managers adding overhead. ───────────────────────────── If you're building something that needs to work at scale, or you've inherited a codebase that's becoming a liability — message me. I'll give you a straight answer on what's actually needed.
