Calebe Aires

I'm a senior full-stack engineer with 14+ years of experience, specializing in TypeScript, React, and Node.js — with production experience integrating LLMs and AI agents into enterprise products. Currently building AI-native UX at BondingAI. Previously tech lead on Gaio, a BI platform where I shipped a chat-driven AI agent for dataset exploration alongside a real-time workflow engine and ETL pipelines.

I work across the full stack — React, Next.js on the front; Node.js, NestJS, Python, Go on the back. I embed directly into product teams — no handoff friction, no translation layer. Available for remote contracts with US-based teams.

AI-augmented development: Day-to-day work with Claude Code across spec, implementation, refactoring, and code review — using custom skills to encode project conventions and recurring workflows.
