Hi, I'm Muslu.

I work across a wide range, from hosting infrastructure and AI agents to multi-tenant SaaS products and open-source tools. Since 2007, I have been running the software I build in production myself.

What I build

About

SaaS & web applications

I build multi-tenant SaaS products and admin panels with Go and Python, isolating customer data with PostgreSQL row-level security.

AI & LLM agents

I build agents on top of language models, RAG systems that answer from documents and Turkish-speaking voice assistants.

Hosting & infrastructure

I set up and run Linux servers, load balancers, DNS and highly available database clusters.

Data & databases

I work with relational, document, key-value and columnar databases, and I have built my own columnar data format.

Desktop, mobile & extensions

I write desktop apps with Go and Wails, Android apps, and browser and IDE extensions.

Payments & integrations

I add virtual POS, PayPal, Paddle and Stripe payments, and WhatsApp, Google Ads and ERP connections to products.
