At Brain Rocket, I designed and implemented a shared JavaScript core to consolidate duplicated business logic across web and mobile applications. I also developed 10+ standalone UI widgets powered by that core.

I owned the shared core’s system design, evaluating integration approaches and architectural trade-offs. I also contributed to monorepo infrastructure, CI/CD workflows, and unit tests for shared business logic.

At Mindtech Studio, I developed frontend features across web and cross-platform projects using React, Next.js, React Native, Svelte, and TypeScript. I improved data-intensive React applications through virtualization and rendering optimization.

I also built AI-powered automation workflows with n8n and LLM integrations, including GitHub code review, conference attendee research, and recruitment workflows. Earlier, at Titanium Technologies, I developed React-based Web3 applications and implemented a Micro Frontend architecture using Webpack Module Federation.
