I work across backend platforms, frontend products, AI-assisted engineering workflows, Web3 user experiences, realtime systems, and data analytics. My priority is not only writing code, but shaping systems that are readable, reliable, useful, and ready to evolve. System Thinking APIs, services, data flows, product boundaries
Frontend Craft dashboards, workflows, responsive interfaces
Backend Delivery auth, billing, reporting, integrations, automation
Data Intelligence preprocessing, analytics, PCA, PLS, monitoring
Product Quality documentation, deployment, observability, testing |
|
AI-assisted engineering workflow backend for repository intelligence, assistant orchestration, reporting, billing, organizations, integrations, and production API delivery. 
|
Production product interface for dashboards, workflow screens, onboarding, pricing, AI-assisted engineering operations, responsive states, and polished user journeys. 
|
Java microservices ecosystem with authentication, users, jobs, file storage, notifications, gateway routing, service discovery, centralized configuration, Docker deployment, and operational documentation. 
|
Go realtime backend with WebSocket chat, JWT middleware, Redis-backed models, migrations, rate limiting, observability, deployment notes, and low-latency service structure. 
|
Swap interface for wallet and no-wallet flows, token selection, route handling, provider state, settings, transaction history, and responsive Web3 product UX. 
|
Explorer-style frontend with global search, transaction detail pages, statistics dashboards, Sankey charts, data tables, filters, and mobile navigation. 
|
Practical preprocessing workflows covering missing data, outliers, Mahalanobis distance, robust covariance, Lasso, wrapper selection, signal denoising, and regression datasets. 
|
Statistical process monitoring with Shewhart, EWMA, CUSUM, PCA, PLS, fault detection, diagnosis, and industrial process case studies.
