I've built API gateways and full-stack product architecture at OptimaJet, integrating the WorkflowEngine BPM core into customer microservice and monolithic systems. I also created architecture for a WYSIWYG form builder with dynamic schema generation and transactional backend logic.

Previously at InferStat, I owned financial analytics features end to end, from database design through interface implementation. I reduced server memory consumption by 35% and built Zod-based JSON validation handling 4,500 RPS.

I bring 8+ years of commercial experience across .NET Core, NestJS, React, and Vue, with a practical focus on database optimization, API-first design, and UI/UX that improves the product experience.
