Building scalable, production-grade web applications with a focus on clean code, performance, and end-to-end ownership. The Value I Deliver: - I build modular, maintainable codebases designed to scale. I prioritize "clean-by-default" patterns that reduce long-term technical debt and simplify team collaboration. - Expert at translating complex Figma systems into pixel-perfect, responsive, and accessible interfaces. I ensure the bridge between design and implementation is seamless and high-fidelity. - Deep optimization of Core Web Vitals and SSR/ISR strategies to ensure lightning-fast speeds, superior user experiences, and maximum search visibility. - I focus on business outcomes, not just tickets. I move beyond the "how" of coding to address the "why" of the product, ensuring every feature serves a project goal. - High-transparency communication with a long-term mindset. I work as a technical partner focused on your sustained success and meeting milestones on schedule. Technical Expertise: - Frontend: React, Next.js, Payloadcms, TypeScript, Tailwind CSS, HTML5, Modern CSS (SCSS/Modules) - Backend & Database: Node.js, NestJS, Express, Supabase, PostgreSQL, SQLite - Design: Figma (Advanced Design Systems), UI/UX Auditing, Design-to-Code Workflows - Embeddable widget / web component - Infrastructure & Tools: Git, GitHub Actions (CI/CD), Docker, Agile/Scrum AI-Assisted & Spec-Driven Development: In an era of agentic workflows, I bridge the gap between AI-generated drafts and production-ready systems by: - Drafting Robust Specifications: Translating abstract requirements into deterministic, implementation-ready technical specs. - Hardening & Auditing: Sanitizing and refactoring AI-generated code to enforce strict type safety and architectural consistency. - Automated Validation: Designing rigorous unit and integration tests to ensure logic remains sound and behavior is predictable. - Debt Prevention: Proactively identifying and eliminating "invisible" technical debt before it enters the production environment.

My goal is to remove technical stress from your side. I take responsibility for building, optimizing, and delivering scalable web applications. I’ve launched multiple production projects and know how to bring ideas into stable, working products. I work with React and Vue depending on the project needs — choosing the right tool, not forcing one. What you get working with me: — clean, scalable frontend architecture (no chaos when the project grows) — fast and responsive UI even with large datasets — attention to edge cases (states, errors, loading, UX details) — ability to work with complex backends, APIs, and real business logic — clear communication and full ownership (you don’t need to micromanage) I’ve worked on: — large admin panels for content/media teams — dashboards with analytics and real-time data — AI-powered tools and document processing systems I don’t just "write code" — I build products that are ready for real users.
