What I Do

Modern Applications.
Full-Stack Solutions.

I build modern web applications with a strong focus on performance, usability, and scalability, combining responsive frontend experiences with reliable backend systems and API-driven architecture.

01. Frontend Engineering

Responsive and accessible interfaces built with React and modern JavaScript, optimized for smooth user experiences across devices.

02. Backend Development

RESTful APIs and backend systems developed with FastAPI and Python, focusing on scalability, authentication, and clean architecture.

03. Real-World Products

Practical applications designed to solve real problems through performance, usability, offline support, and maintainable codebases.

Selected Projects

Progressive Web App

Smart Pomodoro Tasker

A full-featured focus timer built with zero frameworks. Uses IndexedDB for persistent storage that survives browser restarts, an automated focus → break → session workflow, per-task session targeting, and audio notifications generated programmatically via the Web Audio API — no audio files, works offline by definition.

SkyCast — Weather Dashboard

A responsive cinematic weather app with dynamic sky themes, live exchange rates from OpenWeatherMap, atmospheric particle effects, and a full-bleed design system that responds to actual weather conditions. Demonstrates async/await data handling, robust error management, dynamic °C/°F toggling, and JSON transformation for daily summaries — no libraries, no shortcuts.
