>Core member of the founding engineering team, owning end-to-end frontend architecture and key platform decisions across the Web App, Browser Extension, Telegram Mini App, Telegram Game, and Mobile App.

>Owned the SEO-first architecture redesign using Next.js SSR/SSG and deep server-side optimizations, delivering up to 40x faster page loads and major indexing gains.

>Scaled the entire authentication infrastructure using Firebase Auth across Web, Extension, and React Native, enabling secure, unified multi-platform sessions.

>Led a full frontend engineering team during the migration, defining coding standards, review pipelines, system boundaries, and delivery timelines under aggressive deadlines.

>Independently built the entire frontend for a Telegram-based multi-chain swap application, supporting seamless swaps across EVM chains and the TON chain.

>Integrated Web3.js, ethers.js, and blockchain REST APIs for real-time on-chain data access, transaction execution, and cross-chain liquidity routing.

>Implemented wallet connectivity, transaction signing, gas estimation, allowance flows, and EIP-6963, dramatically improving multi-wallet detection and onboarding success.

>Refactored and migrated critical backend services from Python to TypeScript and Go, deploying globally on Cloudflare Workers and background workers with KV-based distributed caching.

>Designed and deployed AWS Lambda and Cloudflare based microservices for transaction processing, automation, and backend orchestration.

>Optimized CI/CD pipelines and cloud build performance for frontend on AWS Amplify, significantly accelerating production deployments and release stability.

>Architected low-level bundling and CI optimizations, achieving a 3x improvement in both local and cloud build performance across pipelines.
