Backend Systems & AI Engineer
Where systems engineering meets product.
ABOUT ME
Hi, I'm Ahnaf. I design and ship production systems that handle complexity at scale, from distributed architectures to AI-powered applications.
Over the past 8 years, I've built real-time messaging systems, container orchestration platforms and distributed video processing backends and complete end-to-end products and platforms.
Most recently, I spent five months at a startup architecting AI agents and agentic workflows into production applications - shipping RAG pipelines, function-calling systems and multi-step workflows that integrate seamlessly with complex backend infrastructure.
I work in TypeScript, Go, and Python, with deep expertise in developing product, distributed systems, production AI agent architecture and database systems.
Currently studying Computer Science; previously Software Engineer at a UK startup. I'm available for consulting and development projects.
FEATURED PROJECTS
Stratus
A multi-tenant Platform-as-a-Service infrastructure I built to understand how platforms like Heroku work under the hood. Current features: Code upload and deployment, intelligent compute node selection based on resource availability, agent-based orchestration, fault-tolerant task distribution with health checks.
Technology used: Go, Python, gRPC, TypeScript/React, Docker + gVisor, PostgreSQL
View on GitHub →Monsoon
A real-time, secure, scalable, end-to-end encrypted messaging platform designed with a zero-trust architecture. It features client-side key generation and cryptographic operations to ensure that raw passwords and private keys never leave the user's device.
Technology used: Go, NATS, Kafka, CockroachDB/PostgreSQL
View on GitHub →MeTube
A custom-built distributed video encoding backend inspired by YouTube - featuring chunked uploads, task queues, and worker nodes for scalable processing.
Technology used: C/C++, RabbitMQ, Flask, Python, FFMPEG, MinIO/AWS S3
View on GitHub →Project LocalDown
A Plex-like system for browsing locally downloaded Light Novels via a centralized UI - featuring a custom data scraper, multilingual full-text search engine, and client-side caching. Multi-device sync and LAN file access coming soon.
Technology used: Python, Flask, TypeScript, React, PostgreSQL, BeautifulSoup

"Throughout Ahnaf's employment, he was able to fulfil every single need of my business. Ahnaf constantly adjusted his schedule to prioritise work and was able to keep up-to-date on a strict work schedule. He was able to develop my business' website and its service within three months of work, which involved setting up email, administration, contact support and ultimately developing the service."
"He continuously conveyed effective time management during the website's development, an ability to communicate and listen to create my vision, the confidence to discuss with me his own ideas and an interest in his work."
"Ahnaf is a good worker - he was able to do everything I asked of him with great attention to detail."
