👋 Hi, I'm Ayush Garg
Backend / Systems Engineer | 7+ years experience | Python - C - Php - Go | (Portfolio)
I build software that cares about performance, correctness, and how things actually work under the hood.
I've spent most of my career working on real-world production systems from legacy codebases to scalable backend services and I enjoy digging into problems that sit close to the OS, memory, and networking layers.
Public projects with private code: p2pchat, ChatToPost
🧠 What I'm into right now
- Doing CTFs from pwn.college and learning cybersecurity.
- Exploring concurrency models, task scheduling, and resource sharing ( learning OS by implementing them )
- Reverse engineering & understanding systems from first principles
🛠️ What I enjoy working on
- Backend systems & APIs that scale and fail gracefully
- Breaking the systems
- Debugging performance & memory issues (the fun kind 😄)
- Low-level programming:
- x86_64 assembly
- Custom memory allocators / deallocators
- File I/O, buffering, caching strategies
- Systems design with a strong bias for simplicity & observability
- Occasionally building games & experiments in C
💼 Experience highlights
- 7+ years building and maintaining backend systems
- Worked extensively with Python, PHP and Golang
- Experience with programmatic advertising platforms (e.g. Kaden AI)
- Comfortable navigating and modernizing large legacy codebases
- Strong at reading unfamiliar code and making it behave
🧰 Tech I work with

🚀 What I'm looking for
I'm currently independent and exploring, open to:
- Backend / systems roles
- Performance-critical systems
- Infra, distributed systems, or low-level problem spaces
If the problem involves "this shouldn't be slow, but it is", I'm interested.

I believe understanding the machine makes you a better engineer.
