AI Integrations, Full-Stack Engineer | SaaS, APIs

Building or scaling a SaaS product? I help companies design, build, and improve web applications—from backend APIs and data systems to full-stack product delivery. Whether you're launching something new or fixing performance issues in an existing system, I focus on clean architecture, scalability, and real-world reliability. I’m a full-stack developer and technical leader with 10+ years of experience leading global teams (up to 11 engineers) and delivering production SaaS platforms across AI, web, and B2B domains. Recently, I’ve been building AI-powered features using LLMs to automate workflows, generate insights, and reduce manual effort—always as part of real applications, not standalone demos. Relevant experience includes: • Built and launched a generative AI SaaS platform (Python + FastAPI + Next.js), reducing research and feature validation time • Architected and developed a SaaS platform for the short-term rental industry (APIs, auth, data systems, AI integrations) • Led the rebuild of a large-scale platform serving 15K+ users, reducing load times by 75% • Designed and delivered production systems with a focus on performance, scalability, and maintainability I’m especially useful when you need someone who can quickly understand an existing system, make solid technical decisions, and deliver clean, reliable solutions without overengineering. If you have something that needs to be built, improved, or scaled—happy to take a look.
