Full Stack Developer | .NET Development Expert | C# Architect I’m a Senior Software Engineer with 10+ years of experience building scalable, high-performance systems using Microsoft technologies, modern frontend frameworks, and cloud infrastructure. I work with startups, SaaS companies, and enterprises that need more than just code — they need solid architecture, long-term thinking, and execution that doesn’t break under scale. Tell me your business goal — I’ll design and build the technical solution to achieve it. Having worked on enterprise-grade systems as well as fast-moving startups, I understand the full software delivery lifecycle — from architecture and development to deployment, scaling, and long-term maintenance. Why should you hire me: ✔ I design systems that scale — not quick hacks ✔ 10+ years of professional development experience ✔ Strong architectural thinking (Clean Architecture, CQRS, scalable APIs) ✔ Deep expertise in C# / .NET / ASP.NET Core ✔ Modern frontend development with Angular ✔ Cloud-native mindset (AWS & Azure) ✔ Clear communication and predictable delivery ✔ I focus on business impact, not just writing code I’m not interested in “one-hour fixes” or short-term patchwork jobs. I build long-term partnerships with serious clients who value quality, reliability, and scalable solutions. If you're looking for someone to just “make it work quickly,” I’m probably not the right fit. If you want it built properly — we’ll work well together. Since early in my career, I’ve been building complex systems including: • SaaS platforms • CRM systems • Enterprise backend APIs • High-volume data processing systems • Cloud-native applications • Cross-platform mobile applications Technologies I work with: • Programming – C#, .NET, ASP.NET Core, Web API • Frontend – React, Angular, TypeScript • Mobile – React Native (iOS & Android) • Databases – MSSQL, PostgreSQL, MySQL, MongoDB • Architecture – Clean Architecture, CQRS, Microservices • Cloud – AWS, Azure • DevOps – Docker, CI/CD pipelines • Version Control – Git I take ownership of the result. I care about clean code, performance, and long-term maintainability. And I deliver what I commit to. If you’re serious about building a reliable, scalable product — let’s talk.
