// about

Engineering that scales

Driven Software Engineer with over 5 years of experience specializing in scalable backend systems, microservices, and AI-driven applications. Expert in Python (FastAPI, Django, Flask) and Node.js, with a deep focus on designing distributed, event-driven architectures using Kafka, Redis, and Celery. Proven track record of deploying production-grade AI solutions, including chatbots and computer vision platforms.

Education

B.Sc. in Computer Science and Engineering

Southeast University · 2023 – 2025

Left to pursue full-time software engineering.

Scalable Backends

Low-latency REST APIs and fault-tolerant services with Python (FastAPI, Django, Flask) and Node.js.

Distributed Systems

Event-driven, high-throughput architectures using Kafka, Redis, Celery, and Temporal.io.

AI & Computer Vision

Production ML integrations — chatbots, face & plate recognition — with OpenCV, Rasa, and FastAPI.

From IoT camera pipelines in C++ to UAE tax-compliance platforms — I like problems where correctness, throughput, and reliability all matter at once.
