One of my most impressive accomplishments is building a social networking platform from scratch, where I now serve as the CTO, leading a team of 7 engineers. I've helped grow the company from inception to securing $3M in seed funding by single-handedly architecting a scalable backend infrastructure using Django, PostgreSQL, and Redis, supporting over 600,000 users with 99.9% uptime by hosting it on Kubernetes. Additionally, I designed and deployed a real-time data pipeline with Kafka and ClickHouse, enabling ingestion of 1M+ daily events. My work also included implementing advanced search capabilities (semantic + keyword based) and working on a real-time, voice based AI-powered interview platform.
You can also check out my latest project, https://semaphore.chat. This is a chat application that offers a streamlined, no-nonsense AI chat experience. It provides access to multiple large language models (LLMs) from various vendors. Key features include markdown rendering of AI outputs, syntax highlighting for code, and the ability to display Mermaid.js diagrams on a canvas. The app supports real-time synchronization and resumable streams using Zero (sync engine), enabling users to share links, and allows for collaborative use of LLMs with peers. Authentication is handled via Google OAuth, the database is Postgres, frontend is in NextJS, self-hosted on a Hetzner server.
