Let's turn the idea we shape together into a digital product.
Product development, end to end.
I build software end to end, from design to production.
I put performance and scalability first, and I care about writing clean, maintainable, readable code.
I take an idea all the way from design to production, making sure the infrastructure is as solid as the user experience.
Alongside the JavaScript and TypeScript ecosystem, I work on CRM, inventory, e-commerce, mobile apps, SEO, performance, and scalable backend architectures.
Real processes. Working products.
A city app that answers "what's on in town this week" from a single place: an Expo mobile client, a Next.js admin panel, and a self-hosted Supabase stack feeding both through one shared data-access layer.
Technical focusRunning a mobile app and an admin panel off one data-access layer and one schema, even though their session models are opposites.
A mobile clinical archive where clinicians and researchers keep patient, case, and follow-up records in one chronological file encrypted on the device — photographs, DICOM, 3D models, documents, and clinical notes all in the same case file.
Technical focusKeeping clinical data encrypted end to end on the device while search, comparison, and multi-format media all keep working inside the same case file.
A portrait mobile match-3 built with Unity 6 and URP, where the matching loop feeds a city-restoration economy rather than a score alone.
Technical focusWiring the matching loop into a progression economy while keeping board resolution isolated from input, and keeping content data-defined rather than coded.
An open-source app that turns the MacBook notch into a native control center, combining safe local backup, media and system controls, and everyday productivity tools.
Technical focusBalancing offline operation, low resource usage, and high functional density in a small space through native macOS integrations.
A system that unifies hotel operations on a single platform — from reservations and check-in to rooms, staff, housekeeping, accounting, and official guest reporting.
Technical focusModeling reservation, official guest reporting (KBS), payment, room, and staff processes as a single fault-tolerant operations lifecycle.
A management system that brings gym operations, trainer workflows, and members' personal progress experience together in independent, per-business deployments.
Technical focusTurning member data into personal progress charts to reduce the trainer's manual tracking workload.
A web platform that unifies land buying and selling in Kütahya through team moderation, structured listing data, advanced filtering, and map-based discovery by drawing custom regions.
Technical focusKeeping the BullMQ media worker and the Next.js ISR cache consistent with each other, and keeping the cinematic design easy to understand for users of all ages.
A Kütahya-focused digital real estate marketplace that brings together listing management, map-based discovery, district and price analytics, pre-valuation, demand matching, and messaging.
Technical focusRunning cookie-based web sessions and a Bearer JWT mobile client safely on the same backend and business rules.
A website that brings a law firm's practice areas, publications, and contact channels together in a trustworthy, responsive corporate experience.
Technical focusBuilding a fast, manageable corporate experience that inspires trust while preserving the client's design language.
A custom e-commerce system built as an alternative to marketplace commissions, unifying sales, variants, stock, shipping, media, customers, and print operations in a single product.
Technical focusBringing a combination-based stock engine, fragmented MNG/DHL services, and the physical store printer together in the same order lifecycle.
A corporate platform that replaces an unwieldy WordPress admin with a clean content panel, combining 4K media, high performance, and a lasting SEO focus.
Technical focusUsing mobile optimization and aggressive cache usage to serve 4K background media without sacrificing speed; embedding SEO directly into content entry.
A modern commerce platform that enabled an Instagram-first boutique menswear brand to move into e-commerce without losing its digital identity.
Technical focusServing high-quality product videos fast through a custom VPS media service and Cloudflare cache.
Let's understand your idea.
I approach a feature not on its own, but within the rest of the product and the real flow of the people who will use it.
I clarify the business process, the users, and what the product actually needs to solve.
I lay out the product flow, the data model, and the system boundaries before writing any code.
I turn complex processes into clear, accessible, and consistent interactions for the user.
I make business rules reliable through the API, the database, and the background processes they require.
I treat testing, security, and performance as part of the development process, not a final checkpoint.
I set up the container, proxy, and deployment layers, and keep monitoring how the product behaves live.
Technical repertoire.
Experience.
Computer Engineering Intern
During my internship I got hands-on with the .NET ecosystem, MSSQL, and enterprise software development practices. In the same period I deepened my knowledge of React, PostgreSQL, and modern full-stack technologies through my own projects, laying the foundations of the technology stack I use today.
Computer Engineering Intern
I worked on developing and improving existing interfaces with React, and supported maintenance, refinement, and development work on the .NET and SQL side. I also contributed to modernization efforts, working with the team on migrating existing applications from .NET Framework to .NET Core.
Right now.
Comprehensive systems where API, queue, cache, and data layers work reliably together.
Systems that bring real operations together through roles, data, and task flows.
An end-to-end development process, from idea to working product to live monitoring.
Native macOS tools that shorten desktop workflows, and small game prototypes in Unity.
Thinking about something new?
I'm open to new projects, freelance work, full-time roles, and technical collaborations.
