I turn raw ideas into production-ready products—fast.
🚀Startup-grade full-stack & AI engineer, coding since 2005: first hire at several startups, two of which exited via IPO or acquisition. 100 % Job Success and ★★★★★ over 10+ years on Upwork.
Key wins:
• Built & shipped two VC-funded startups—both now 7-figure businesses
• Integrated 50+ third-party APIs, libraries and cloud services across diverse projects—always with clean code and best practices
• Added newest-Tesla vehicle support to the FrogPilot fork of OpenPilot ADAS—ramped up and delivered code in a few days

What I bring to your project
• Speed without shortcuts – battle-tested patterns carve months off timelines while keeping code clean & covered
• AI advantage – build and integrate custom AI tools (GPT copilots, vector search, data classifiers) and use AI myself to accelerate development
• Full product ownership – database schema ➜ pixel-perfect UI ➜ DevOps automation
