Full-Stack Developer

Summary

Full-stack developer who builds and runs production systems for small businesses: WhatsApp bots with AI order parsing, e-commerce catalogs, admin dashboards and SaaS apps. I own projects end to end, from data modelling and integrations (Gemini, Lalamove, Evolution API) to Docker-based deployment, CI and monitoring on a VPS. I run my own studio, Hal-Creative.
