Message

At Edunio, I’m building the backend and infrastructure for an exam-prep platform for Turkish national exams. I designed its data model and Go API, and set up PostgreSQL, Redis-backed sessions, and secure cookie-based authentication.

At Kondukto, I designed the shared Go client framework behind 20+ production integrations and built a concurrent job-processing engine with rate limiting and retries. At Symphony, I led a six-person Go team delivering a gRPC data layer for a client GIS platform.
