👋 Hi, I'm Rezoan Ahmed Abir

Software & Platform Engineer | Distributed Systems · Cloud Infrastructure · AI Systems

I’m a Software Engineer interested in understanding and building the systems behind modern applications, from distributed backends and cloud infrastructure to LLM-powered applications.

My work spans application development, Kubernetes infrastructure, backend systems, and lower-level experiments with Linux networking and virtualization.

  • 🔭 Currently working on Lipika AI at Iterosys and Lockton People Solutions via AGT Software Partners
  • 🧪 Exploring Distributed systems, HPC, Linux internals, Virtualization, and cloud-native infrastructure
  • 💬 Ask me about FastAPI, Kubernetes/GKE, Agentic workflows, AWS/GCP, or eBPF/XDP
  • 📫 Email · LinkedIn

What I'm Interested In

Distributed & Cloud Systems

Distributed architectures, Container orchestration, Kubernetes, Cloud infrastructure, Concurrency, Reliability, and Scalable backend systems.

Systems & Virtualization

Linux internals, eBPF/XDP, KVM/QEMU, Firecracker, gVisor, Container runtimes, Networking, and Sandboxed execution.

AI Systems

LLM applications, Agentic workflows, RAG pipelines, Context Aware Document Processing, and the infrastructure required to run AI workloads safely and reliably.

Recent Works

Secure Code Execution for AI Agents

Implemented a Kubernetes-backed sandbox execution system for AI agents using FastAPI, GKE, gVisor, Redis, GCS, and Python.

The system provisions isolated execution environments, stages user files, executes generated Python code, manages sandbox lifecycle and concurrency, and returns generated artifacts to the application.

Cloud & Backend Systems

Building production backend services and cloud infrastructure across AWS and GCP, including serverless workloads, containerized applications, CI/CD pipelines, object storage, databases, and Kubernetes deployments.

Systems Experiments

Exploring Linux networking and virtualization through hands-on implementations involving eBPF/XDP, SO_REUSEPORT, KVM/QEMU, Firecracker, and container isolation.
