About

I architect the systems behind a hospitality platform — Go services, booking engines, custom DNS servers, AI search — and the interfaces on top of them. Backend-heavy, frontend-fluent, owner of things end to end.

/ The work behind it

The last few years at SaffronStays meant migrating Node.js APIs to Golang for a 150%+ improvement in response times, building an NLP chatbot and villa recommendation engine on Python and Elasticsearch, and shipping SYNC — a full inventory dashboard with a calendar built entirely from scratch. Lately the work goes lower in the stack too: a custom DNS server with automatic SSL, powering white-label hosting for an entire platform.
