What I'm looking for

I’m available for freelance work and nearshore roles with international clients.

At Code Assurance, I develop business management applications with React, .NET Web API, and SQL Server. I also implement LLM and n8n automations that eliminate 12 hours of manual data entry per week in client SMB processes.

I designed and shipped Opero and JoinMe, my own products, from architecture through deployment. Opero is a web-based ERP actively used by four companies, and JoinMe is an event and digital invitation platform.

Previously, I developed business applications at Fortek Solutions and RCM Technologies, and industrial monitoring platforms at Detect Technologies. I’m available for freelance work and nearshore roles with international clients.
