K M AHNAF ZAMIL

Backend Systems Engineer

I build scalable backends that don't break under pressure.

ABOUT ME

Hi, I'm Ahnaf. I build scalable systems, distributed architectures, and developer platforms.


I've been coding since I was 13. Over the past seven years, I've built real-time messaging systems, container orchestration platforms, and distributed video processing backends-mostly to understand how production systems work under the hood.


I work primarily in Go and Python, focusing on distributed systems, message queues, database scaling, and infrastructure that handles load without breaking. I'm comfortable moving between backend development and systems architecture.


Currently in university while actively looking for part-time and contract work with startups building technically challenging products.


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

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

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

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

TESTIMONIALS

"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."
