Software Architecture & Technical Advisory
Architecture decisions, system design, technical roadmaps, codebase reviews, and engineering process improvement.
Japan-experienced · Founder of Kodart · Worldwide
I help companies build secure, scalable mobile, backend, AI, and realtime systems — shaped by 20+ years of software engineering experience and 11 years of Japan-based engineering discipline.
I've been coding since 1994, when I was 9 years old. What started as a childhood obsession turned into 20+ years of professional software development across mobile, backend, frontend, realtime, and AI-enabled systems.
I build native iOS apps in Swift and SwiftUI, cross-platform mobile products in Flutter, and backend systems in Node.js, Elixir, C#, and Python. My work usually sits close to the product architecture: system design, delivery tradeoffs, security risks, team practices, and the decisions that determine whether software remains reliable after launch.
I've shipped apps to the App Store and Google Play, built real-time audio pipelines, IPTV systems, social networks, AI-powered products with multi-LLM architectures, and Kubernetes management platforms. My background includes Technical Architect, Security Champion, and team lead responsibilities across production software.
I spent 11 years living and working in Japan. That experience shaped a calm, direct, detail-oriented engineering style built around reliability, maintainability, clear communication, and practical product execution. I now help companies commercially through Kodart.
My engineering approach was shaped by years of building production software and by more than a decade of living and working in Japan. I care about reliability, clarity, maintainability, thoughtful architecture, and software that survives real users — not just demos.
I currently help companies through Kodart, an Estonia-based software and AI engineering studio. Kodart works with companies worldwide, with a practical focus on Turkey and Europe. The work includes software architecture, secure software development, mobile and backend systems, AI integrations, realtime communication products, and technical advisory.

Professional Highlights
RotaTalk is a voice-first communication product for truck
drivers, involving mobile apps, realtime audio, backend
architecture, AI assistant concepts, and location-aware product
design. It is built end-to-end in Flutter (iOS & Android)
with Node.js & Elixir backends. Real-time voice channels use
LiveKit with hands-free push-to-talk, a driver social feed for
road intelligence, live map with opt-in location sharing, and
private team channels for fleet coordination.
RotaBot, the built-in AI road assistant, handles truck-safe
routing via TomTom, HERE, real-time traffic & roadworks, fuel
price comparison, and border crossing intelligence — powered by a
multi-LLM agentic backend (Gemini, ChatGPT, Claude) with automatic
fallback, per-provider budget controls, Redis-backed cost
tracking, and SSE streaming to mobile. Available in 11 UI
languages, 187 conversational languages. Live on the App Store and
Google Play.
A social venue search engine with 1M+ registered and active users, later acquired by Zomato. Built the entire stack end-to-end: backend, frontend, admin panel, and iOS & Android applications.
Japan's internet television streaming service. Android Lead Engineer in a team of 3. Managed complex API integration, high-volume JSON data processing, and high-performance UI rendering under heavy load.
Large-scale file transfer application. Joined as iOS Architect, defining the iOS architecture from the ground up and leading development of the platform's new iOS product.
The #1 sports website in Turkey. Led a team to rebuild the platform from scratch for the 2010 FIFA World Cup using .NET 4.0. Architecture still in use today. Won 8+ national awards.
Transformed a paper loyalty card into a full digital system — solo, in 4 months. Delivered iOS & Android apps, backend API, and Microsoft Dynamics CRM integration for an international coffee chain.
IPTV platform for Turkey's leading GSM operator. Built a real-time log analysis tool in Node.js using regex pattern matching on syslog to detect and surface bugs instantly for the development team.
Turkey's top travel booking platform for hotels, flights, and tours. Rebuilt from scratch with a 3-person team. Architecture still in use today. Won 4+ national awards.
Location-based social networking app where users check-in and post media. Senior Engineer on both backend (Firebase) and mobile (Flutter). Also served as Security Champion for the product.
An internal Kubernetes cluster management platform. Developed the distributed lock mechanism using Redis Redlock and built a complete billing system from scratch. Backend & Frontend Engineer.
Personal healthcare monitoring system with two-way device sync, concurrency-safe architecture, and real-time chat via SignalR. Backend Lead Engineer in a team of 4.
Open Source Contributions
Contributed to the #1 open-source mobile analytics platform, used by billions of devices worldwide. Fixed iOS SDK bugs, added concurrency features, and provided UX feedback that shaped the Countly Cloud platform.
Active contributor to this non-profit interactive periodic table with 400+ GitHub stars. Contributes to the backend and open-source community management for the educational science project.
Personal Projects
Open-source real-time counter for shared spaces, built during COVID-19 to help people avoid crowded areas. Full-stack: Elixir/Phoenix backend and SwiftUI iOS app.
