Istanbul, Türkiye · UTC+3
I'm Veysel Aksin, a software engineer based in Istanbul. I work primarily on backend systems, distributed architectures, and AI-powered products — from infrastructure to applications people actually use.
/work
A few things I've built, shipped, or experimented with.
Local-first · macOS · Android
A local-first bridge between Mac and Android for sharing clipboard content, files, photos, and videos directly between devices.
No cloud. No account required for transfers. Your devices talk directly.
nexusdrop.appGo · Swift · Kotlin · WebSocket · Firebase
Developer Tools · macOS
A local-first developer dashboard that brings infrastructure and engineering signals into one place — Docker containers, SSH server metrics, GitHub activity, and developer tooling.
Swift · Docker · GitHub · SSH
GitHubOpen Source · Go Package
A rate limiter library for Go, inspired by node-rate-limiter-flexible. Token bucket, leaky bucket, sliding window, and fixed window strategies with Redis, Memcached, or in-memory backends.
Go · Redis · Memcached · Docker
GitHubDesktop Productivity
A desktop workspace designed around contexts rather than individual applications — helping separate work, communication, and personal environments.
View Shelf/engineering
I enjoy working on problems where software architecture, infrastructure, and product decisions meet.
/experience
Building and maintaining AI-powered products — architecting and fine-tuning LLM integrations (OpenAI, Claude, Grok, Gemini, LLaMA) with LangChain, alongside backend services and payment infrastructure (Stripe, Paddle, Adapty) for mobile applications.
Led a cross-functional team building the Trendpos web and mobile applications — architecting backend systems, modernizing legacy code, and managing cloud infrastructure on Azure and AWS.
Built scalable internal systems and public-facing websites for the Ministry of Culture and Tourism, including the Rami Library and Choir projects, using Python, Django, FastAPI, and Go.
Developed an internal operations dashboard and built the Robotistan search engine from scratch, along with cron-triggered web-scraping pipelines for data collection.
Helping organize and grow Istanbul's Go developer community through technical events, talks, and community activities. A small way of giving back to the language and people that shaped a lot of this work.
/now
/about
I like building software at the point where engineering and product meet.
My background is primarily in backend engineering, especially Go and distributed systems. More recently, I've been working deeper into AI engineering — building systems around LLMs, orchestration, tool use, and AI-powered applications.
Outside of work, I organize Istanbul Gophers and build independent products and experiments like the ones above — mostly local-first tools and things I wished existed.
Education
Computer Engineering, B.Sc.
/writing
Notes on software engineering, systems, and things I learn while building.
