I’ve built and shipped full-stack web applications for local and international clients across fintech, e-commerce, and healthcare, taking projects from design to deployment. In my freelance work, I’ve also integrated LLM-powered features, including a RAG chatbot that answers questions using clients’ own documents.

At Zoobook Systems LLC, I built a C#/.NET and JavaScript autosave system for clinical documentation to prevent data loss from session timeouts and browser crashes. I also delivered paid features for configurable workflows and resolved production issues reported by customers and QA.

At Eskalate, I improved API response times by adding Redis caching to Golang endpoints and resolving an N+1 query problem. I’ve also built personal projects including Gabaasio, a multi-tenant reporting platform, and LinkedCode, a real-time collaborative coding platform.
