Things I've built
Distributed microservices, scalable backend systems, and OTA platforms — engineered with Golang, gRPC, Kafka, PostgreSQL, and Redis.
CartUp (E-Commerce)
Engineered decoupled Go microservices for core Product, Order, and Customer domains, using gRPC for type-safe inter-service communication and Kafka for event-driven, asynchronous workflows — built for horizontal scalability.
Apeiro
Engineered backend microservices for a Canada-based subscription digital service provider, powering immersive AR/VR and 3D experiences. Built event-driven services with RabbitMQ and gRPC for inter-service communication, backed by PostgreSQL and a NestJS/Next.js application layer.
FirstTrip
Contributed to a high-traffic travel booking architecture at TechnoNext, optimizing query execution and elevating front-end performance for a smooth user experience. Managed complex hotel and holiday booking modules.
SkyTrip
Built core flight booking and reservation features for BDTask's travel platform, integrating airline APIs and B2B agent workflows while tuning the backend for reliable, high-throughput ticketing operations.
Benemoy Securities — OMS (DSE)
Engineered an Order Management System for the Dhaka Stock Exchange, building high-performance React.js trading interfaces backed by Golang services. Optimized state management and real-time data flows with Redis to handle complex, high-frequency market data, with Python powering analytics and processing workloads.
Vibrant African Journeys
Built a tour booking platform for a Ghana-based travel operator offering cultural immersion, safari, and multi-day package tours. Developed the Next.js front-end with a Strapi-powered backend for managing tour packages, and integrated Stripe and PayPal for secure customer payments.
High-Performance Backend System
Designed a multi-tier Redis caching layer and optimized PostgreSQL access patterns for a high-throughput backend, cutting API latency to sub-millisecond ranges while preserving strict ACID transactional guarantees under heavy concurrent load.
