About

Backend systems, incident timelines, and tradeoffs that show up after real traffic starts.

I'm a backend software engineer with 5+ years of experience building enterprise software across the energy, industrial IoT, smart city, and enterprise automation domains, including solutions for financial services. Most of that work is Node.js and TypeScript services that move data across queues, databases, and APIs, where Kafka consumer behavior, retry semantics, and idempotency matter more than feature velocity.

For the last three years I worked on grid operations software used by electricity distribution operators: outage management and low-voltage management platforms with event-driven pipelines on Kafka and BullMQ, hierarchical authorization modeled as a graph in RedisGraph, and recursive PostgreSQL queries over network topology where query plans directly drive user-facing latency. Alongside that, geospatial data with PostGIS and GeoServer, and integrations with enterprise systems including SAP.

I hold an MSc in Computer Forensics, which shapes how I think about secure software development and system reliability. This site documents debugging paths, architecture decisions, and operational constraints from running distributed backend systems, not motivational filler.

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.
