Overview 11,000 hours of front-end development. Angular from early versions all the way to v20. React, Next.js, Java, Spring Boot, Hibernate. That's the foundation. What's changed: I now use Claude Code daily to move significantly faster without dropping quality. Vibe coding gets a bad rap when developers use it as a shortcut. I use it as a force multiplier — the architecture decisions, performance thinking, and production discipline are still mine. The speed is just... different now. What that means for your project: Features that used to take a week get done in days. Complex upgrades that used to take months get done properly and fast. You get a decade-level specialist who ships like a team. ⚡ What I've built Real Enterprise Scale - the most recent project (Angular + Java) 190-component multi-tenant Angular SaaS — 994 TypeScript files, ~33,000 lines of production code, 267 SCSS files, 186 HTML templates Architected and maintained 79 NgRx files — feature-level state provisioning, polling effects, and a custom Rison-encoded router serializer handling complex URL state 275 domain model files (92 enums, 54 interfaces, 129 classes) — full type-safety investment across a steep, high-stakes domain Solved 4GB build heap challenges — strict template checking across 186 templates, bundle size optimization, change detection tuning under real production load Bearer token auth with HTTP interceptor, SSO/federated login across multi-tenant routing Datadog RUM production monitoring — real-time performance visibility in a live enterprise environment 33 Cypress e2e tests covering approval workflows and collaboration features, 95 Karma/Jasmine unit tests 25 dedicated API service classes integrating with a versioned Java backend (331 REST endpoints across 5 API versions) 32 adapters bridging backend DTOs to frontend domain models — clean separation between API contract and UI state React & Next.js — Selected Projects Built a full-stack local marketplace platform — Next.js App Router, React Server Components, Server Actions, TypeScript — with seller dashboard, pickup/delivery logistics, and shopper-facing storefront Implemented role-based auth with Auth.js — email/password and OAuth flows across 3 roles (admin, seller, shopper) State management with Redux Toolkit for cart and session, React Query for server data — clean separation between client and server state Integrated Algolia/Meilisearch for fast product search, Stripe for payments, PostgreSQL via Java backend REST/GraphQL APIs PWA-ready with SEO optimization — performance and discoverability built in from the start DevOps setup with Bitbucket, ESLint/Prettier, Playwright end-to-end testing Backend — Java & Spring Boot Built REST APIs with Spring Boot handling document upload and processing — integrated Apache Tika for file parsing and iTextPDF for generation, managed async processing to avoid request timeouts Worked on Hibernate entity optimization in a complex domain model — identified N+1 query issues, applied fetch strategy fixes and DTO projections, improved response times noticeably Participated in a monolith-to-microservices migration — helped set up Spring Boot services, MySQL and Elasticsearch integration, supported dual-write pattern during transition Implemented Spring Security with JWT authentication — role-based access control, integrated with existing multi-tenant user management 🏆 How I work Product-minded development — I think about what you're building, not just the ticket. Strong communicator, independent problem-solver, deadline-focused. My clients consistently mention this in reviews. I write clean, well-documented, maintainable code that your next developer won't curse you for. 📞 Let's talk about your project.
