What I'm looking for

I’m looking to lead backend engineering and architecture for distributed, event-driven systems—especially payment orchestration. I want a team where I can mentor engineers, improve reliability and performance, and modernize production services using .NET.

I’m a Senior Software Engineer and Lead Engineer with 10+ years of experience designing, developing, and scaling enterprise backend systems, distributed platforms, and high-performance applications. I focus on building reliable, scalable, and maintainable services while driving architecture and technical decisions from concept to production.

I’ve integrated external payment providers and designed payment orchestration flows that handle asynchronous payment workflows securely and reliably. I build secure, scalable REST APIs for enterprise platforms and use clean architecture practices to improve maintainability and correctness.

My day-to-day strength is the Microsoft technology stack—.NET 10 and ASP.NET Core Web API—combined with microservices, distributed systems, and event-driven architecture. I’ve worked extensively with MongoDB, PostgreSQL, MSSQL, Entity Framework Core, and Redis, plus messaging and realtime solutions using RabbitMQ, SignalR, and WebSockets.

I lead backend initiatives, mentor engineers, and collaborate closely with frontend and QA teams to deliver production-ready features. I also leverage AI-powered development tools (Claude, GitHub Copilot, Codex, Make.com) and modern DevOps practices (Docker, Kubernetes, Jenkins, Azure DevOps) to accelerate delivery, strengthen testing, and improve performance through monitoring and troubleshooting.
