Senior .NET Software Engineer
Mehmet Can Akay
Backend systems for banking, insurance, and healthcare — built for scale and maintained for the long run.
Seven years of backend engineering in regulated domains: high-throughput services, resilient third-party integrations, and the background-processing layers that keep them dependable. I write about the patterns and trade-offs here.

Focus
Scalable backends with clear ownership
From core banking APIs to insurance rule engines and clinical data pipelines — I design services that stay fast under load and remain maintainable as domains grow.
Architecture modernization
DDD, microservices, and legacy layer refactors
- DDD
- Microservices
- Docker
Operational reliability
Background jobs, integrations, and caching strategies
- Hangfire
- Azure
- Redis
Selected work
Projects that show how I think
These are in-house enterprise systems, so the implementations stay private — the engineering approach behind them is in my writing.
Runtime Rule Execution Service
Versioned business logic compiled and executed at runtime, so product rules change without a redeploy. Per-environment releases, distributed locks, and full tracing.
- .NET 8/10
- Roslyn
- Custom DSL
- JSON-RPC
Partner Risk Assessment
Questionnaire-driven risk scoring for a bank partnership channel: real-time results, PDF reports, OTP verification, and lead routing into branch queues.
- .NET Core
- MSSQL
- Azure
- Secure APIs
High-Volume Messaging Operations
Webhook-driven backends that ingest heavy daily volumes of claims, requests, and complaints, then route each one into the right operations queue.
- .NET Core
- MediatR
- Hangfire
- Webhooks
Student Information System Modernization
A legacy monolith serving several universities, refactored into DDD-aligned microservices with Dockerized delivery.

- Angular
- DDD

Notes from the trenches
Configuration-Driven Recurring Jobs in Hangfire — and Skipping Overlaps Instead of Waiting for Them
Schedules declared in configuration, and a filter that skips overlapping recurring runs instead of waiting for them.

Yerel LLM sistemlerinde backpressure ve ölçekleme
Kapasite istek sayısı değil, KV bütçesidir. Eşzamanlılık, preemption, admission control ve goodput ile yerel LLM servisini hedeflenen gecikmede tutmak.
