I'm a passionate Backend Developer from Dhaka, Bangladesh, with 2+ years of experience architecting microservices in Python and Rust. I specialize in building scalable APIs, AI-powered systems, and high-performance backend services using Django, FastAPI, and Actix-web. My expertise spans PostgreSQL, Docker, cloud infrastructure, and real-time system design — always engineered for reliability and speed.
- Microservices Architecture: Designing and deploying distributed, fault-tolerant systems using Python and Rust that scale under pressure.
- AI-Powered Backends: Building intelligent backend systems — from NLP-driven WhatsApp chatbots to AI product recommendation engines.
- High-Performance Rust Services: Leveraging Actix-web for performance-critical components where latency and throughput are non-negotiable.
- API Craft: Developing robust REST APIs and gRPC services with clean documentation (Swagger/OpenAPI) and secure JWT/OAuth authentication.
- Cloud & DevOps: Containerizing with Docker, deploying on AWS, orchestrating with Nginx & Pingora, and automating with CI/CD pipelines.
- Database Mastery: Optimizing complex queries across PostgreSQL, MongoDB, Redis, and Pinecone for performance at scale.
- Payment Systems: Integrating Stripe, PayPal, Moncash, and Coinbase Commerce for seamless, multi-currency payment workflows.

- chaskixstudio.com — Multi-vendor SaaS booking platform with real-time availability, RBAC, and automated payment workflows. (Django, DRF, PostgreSQL, Redis)
- thesocialmarket.ai — AI-powered social marketplace REST API with JWT auth and role-based access for vendors and clients. (Django, DRF, PostgreSQL, Redis)
- themaglevclub.cloud — Insurance agency management system for tracking agent performance, mentor assignments, and feedback. (Django)
- AI Product Recommendation System — Chatbot using GPT-4 that converts natural language to Pandas operations for intelligent product search. (GPT-4, Pandas, Streamlit)
- Movie Streaming Backend — High-concurrency streaming service with sub-second startup times using Rust microservices. (Actix-web, Rust)
- Performance-Obsessed: I pick the right tool for the job — Rust when microseconds matter, Python when velocity does.
- Clean Architecture: I design systems that are modular, maintainable, and built to evolve — not just to ship.
- AI Integration: I bridge the gap between ML models and production-grade APIs, building systems that are actually intelligent.
- Full API Lifecycle: From schema design to load testing with Grafana & K6, I own the entire backend delivery.
- Cross-Functional Collaborator: I work closely with frontend teams, reducing integration friction and eliminating bugs at the seam.
- Always Learning: Whether it's a new Rust crate or a distributed systems pattern, I'm never done growing.
I'm open to exciting backend challenges — whether it's a high-throughput API, a real-time data pipeline, or an AI-driven platform. Let's engineer something that lasts.
