About Me

Crafting interfaces that users love and codebases developers appreciate.

I'm a Frontend Developer based in Bursa, Türkiye | Remote with a Computer Engineering background. Over the past 5+ years, I've focused on building web applications that are not just functional, but performant, accessible, and maintainable.

My approach centers on solving real problems through thoughtful architecture. Whether it's reducing load times by 40% through code splitting and lazy loading, or building reusable component systems with Storybook, I prioritize measurable impact over superficial complexity.

I thrive in collaborative environments, working closely with design and backend teams to translate Figma mockups into pixel-perfect, mobile-first implementations. I believe great frontend development is about bridging the gap between design vision and technical reality.

Real-World Impact

Production applications built with focus on performance, scalability, and user experience.

Corporate Website

Ay Tarım - Corporate & Export Website

Freelance • Solo Developer

Built a multilingual corporate and export-facing website with Next.js App Router and SSR, structured around what a buyer actually needs to qualify a supplier: the company story, a garden-to-shipment process narrative, a catalogue of apple varieties (Gala, Fuji, Red Delicious, Granny Smith, Golden), a facility gallery, and direct contact. Turkish, English, and Russian are served as fully localised, separately indexable routes with hreflang and localised metadata, since the export markets are the point. The design is image-heavy but weight-conscious — optimised imagery, lazy loading, and responsive layouts keep it fast on mobile connections in the field.

Mobile App

Bakio - Personal Finance App

Personal Project • Solo Developer

Bakio is a cross-platform mobile app built end-to-end as a solo project and shipped to both the App Store and Google Play. It focuses on the essentials: adding income and expenses, organising them into categories, browsing transaction history, and turning that data into clear analytics and reports. Multi-currency, multi-language, and dark mode support make it usable anywhere, and the interface is deliberately kept minimal so logging a transaction takes seconds.
