What I'm looking for

I’m looking to build scalable backend services and integrations in a team that values clean architecture and performance. I want ownership of REST APIs end to end and opportunities to automate workflows that connect real systems.

I’m a Backend Developer specializing in .NET (C#), focused on building scalable APIs, integrations, and automation workflows. I care about performance, clean architecture, and delivering reliable backend solutions.

At Bechsud (2022–Present), I designed and implemented backend services with .NET (C#), developing REST APIs and JSON-based integrations with external systems. I built and maintained integrations that improved data flow and reliability, and I resolved production issues through debugging, log analysis, and performance optimizations.

Previously at ADV Technology (2021–2022), I maintained and optimized existing modules to ensure proper functionality and better application performance. I also developed new modules from scratch based on business requirements, expanding system capabilities.

I’m especially interested in end-to-end automation and system interaction. In my project “AI Content Automation System,” I built an automation workflow using Python and Playwright to connect content generation, scheduling, and publishing across platforms.
