Igor S.

I am a software developer with over 12 years of experience creating and maintaining applications across a wide variety of projects and product spaces. Focused on JavaScript/TS, mainly React and Node.js, with an AI-first development workflow built around Claude Code and Codex.

I've been a full-time freelancer for over 10 years, working with clients ranging from small startups to Fortune 100 companies.

AI-assisted development is at the core of how I work today — the majority of code I ship is built with LLMs in the loop, covering end-to-end feature development, large-scale refactors, and automated workflows. I know how to get the most out of frontier models while keeping code quality high: reviewing, validating, and correcting AI output rather than trusting it blindly. I'm also experienced in auditing and hardening AI-generated and vibe-coded codebases, taking them from rapid prototype to production-ready. Beyond tooling, I've built AI-powered products directly — LLM integrations, agentic workflows, RAG pipelines, and AI-driven content processing.

I can build any project from the ground up and have experience with all stages of development of enterprise-grade platforms — from developing an MVP, reviewing UI designs and technology choices, getting it ready to release, releasing the platform, and maintaining it.

I am skilled at writing well-designed, testable, and efficient code using current best practices. I am a hard-working and responsible person, able to work by myself or in a team.
