Work Experience

Lead Software Developer

2015 - 2024

Adeva

Acted as a software developer for a US-based waste management startup. The most challenging parts of the project were the dynamic pricing algorithm and the driver route-optimization features. Those led the client to a successful fundraising round.
Served as a software developer for a legacy art project for a Swiss-based startup. The challenge was a 3D image composition that lets you visualize how a piece of art would look in your room. I learned a lot about image manipulation.
Worked as a lead developer for a New York-based startup. Client meetings and team coordination were the basics. We lacked a DevOps department, so I handled deployment, infrastructure, security, requirements management, and much more.
Acted as a lead developer and software architect for a healthcare-oriented corporation. Completed several system designs and contracts successfully, honored BRDs, and pushed for CR when needed.
