Backend Developer at MeeApps building BIST brokerage systems and replacing a portfolio platform with a new module.

Turkey

Message

At MeeApps, I develop services for a Borsa Istanbul (BIST) brokerage backoffice supporting live trading operations. I built a portfolio management module to replace an undocumented third-party platform, mapping portfolio managers’ workflows into the new system.

I also built gRPC integrations with a FIX service for live market data and addressed PostgreSQL lock pile-ups during order bursts. At Getir, I owned my team’s observability migration to a self-hosted Grafana, Prometheus, Mimir, Loki, and Tempo stack, and built Go and MongoDB services for operational reporting.
