About

I'm a Senior Full-Stack Software Engineer with extensive experience designing, developing, and supporting enterprise applications, SaaS platforms, APIs, and business systems using C#, .NET, ASP.NET Core, SQL Server, PostgreSQL, MySQL, React, Angular, JavaScript, TypeScript, Azure, and AWS.

Throughout my career, I've delivered solutions across a variety of industries, including healthcare, AML/KYC compliance, financial services, retail POS systems, CRM platforms, and customer-facing web applications. Many of these systems support business-critical operations in production environments.

My expertise spans the full software development lifecycle, from requirements gathering and system design to development, deployment, and production support. In my previous role, I led a team of three engineers while remaining hands-on in architecture, development, troubleshooting, and delivery.

My strongest technical skills include C#, .NET, React, SQL Server, API development, cloud technologies, and enterprise system integrations. More recently, I've expanded my expertise into AI-powered applications and workflow automation using Python, FastAPI, OpenAI APIs, n8n, and Supabase to improve business efficiency and automate operational processes.

Since 2016, I have worked successfully in remote environments, collaborating with distributed teams across different time zones. I am a quick learner, adaptable to new technologies and business domains, and enjoy solving complex technical challenges while delivering scalable and maintainable software solutions.

I am currently seeking a Senior Full-Stack Engineer opportunity where I can contribute to building high-quality software products, support technical decision-making, and help drive successful project outcomes.
