Experience

Production backend work across energy grid operations, industrial IoT, and enterprise automation.

Inavitas

March 2023 – July 2026

Full Stack Developer (Backend-Focused)

Ankara, Turkey · Energy sector: grid operations software for electricity distribution

  • Designed and developed backend-heavy microservices for the Outage Management System (OMS) and Low Voltage Management (LVM) platforms that electricity distribution operators relied on to detect, track, and resolve grid incidents in production.
  • Architected event-driven and asynchronous processing pipelines on Kafka and BullMQ for real-time outage and low-voltage incident workflows, decoupling services so incident processing stays responsive under bursty, high-volume event load.
  • Modeled hierarchical authorization and complex domain relationships as a graph in RedisGraph, propagated through Redis Pub/Sub, consolidating permission logic that had been scattered across services into a single queryable model.

Transactional Outbox in NestJS: Lessons from a Geofencing Microservice

A database transaction and a Kafka publish cannot be made atomic. Here is how the outbox pattern closes that gap in a NestJS + PostgreSQL service: the table, the relay worker, and the idempotency work it forces onto every consumer.
