At Antier Solutions, I've spent 5+ years growing from a feature contributor into an engineer who owns full product modules end-to-end — architecture, frontend, and backend — across fintech, healthcare, and Web3 products. I architected a centralized reusable component library in React and TypeScript, adopted across 3+ product lines (Wallet, Exchange, Explorer), cutting duplication and speeding up feature delivery by 40%. I also drove performance work platform-wide — reducing API response times by 30% through Redis caching and database optimization, improving First Contentful Paint by 40%, and cutting bundle sizes by 35% through Vite/Webpack optimization. On the full-stack side, I built Risely, a hybrid fiat-and-crypto digital banking platform — architecting KYC verification microservices and an event-driven notification system handling ~3,000 identity verifications daily with 99.5% uptime. I also built a real-time blockchain explorer handling over 1,000 transactions per second at sub-1-second sync latency, scaled to 10,000+ concurrent users. More recently, I led frontend architecture for StayHealthy, an AI-powered health platform — integrating LLM-based coaching features, Stripe subscriptions, and a complete onboarding-to-recommendation user journey using Next.js. Alongside delivery, I've mentored junior engineers on React, TypeScript, and component-driven development, and worked cross-functionally with design, backend, and QA in Agile/Scrum environments — increasingly taking ownership of technical and architectural decisions across teams.
