Hi, I'm a Backend Software Engineer
I'm Awolad Hossain, a backend engineer specializing in high-concurrency distributed systems using Go, Node.js/NestJS, and PostgreSQL. I focus on database performance optimization, distributed locking strategies (Redis), and secure containerized environments.
About Me
I'm Awolad Hossain, a Backend Software Engineer from Bangladesh. I specialize in building high-concurrency distributed systems, optimizing database performance, and designing scalable API services using Go, Node.js/NestJS, Prisma, Docker, and PostgreSQL/Redis. My journey in software engineering has been driven by optimization and complex problem-solving. I love turning concepts into robust, production-ready backend systems.
I'm open to Job opportunities where I can contribute, learn and grow. If you have a good opportunity that matches my skills and experience then don't hesitate to contact me.

My Experience
Professional software engineering experience and technical achievements.
Backend Software Engineer
Neocoder (Akij Venture Ltd)- Engineered and optimized 5+ core enterprise HRIS and workflow automation endpoints using NestJS, cutting employee onboarding processing overhead by 42% and improving API scalability across the system lifecycle.
- Architected the backend service for the Store Sales & Inventory Module, streamlining warehouse-to-branch inventory transfers via multi-step, validated Transfer In/Out schemas with zero data mismatches.
- Implemented strict database-level transactional rules with Prisma, ensuring 100% data integrity for 5,000+ concurrent daily inventory and stock transactions.
Software Engineer
ASG SHOP™- Developed a multi-tenant centralized institution management system leveraging Node.js, Prisma, and PostgreSQL, efficiently isolating platform-wide relational data for multiple tenants.
- Designed and deployed a granular Role-Based Access Control (RBAC) infrastructure using custom caching middleware, securing API endpoints with permission-based access validations.
- Optimized complex SQL queries and database schemas to support an institutional hierarchy and real-time reporting, reducing query latency for large data aggregates by 30%.
Software Engineer Intern (Backend-Adjacent)
NTS Nihon Global- Developed and integrated high-performance RESTful APIs for secure user onboarding, session management, and token-based authentication modules.
- Implemented backend network interceptors and data-caching layers, improving API response handling and reducing duplicate database queries.
- Restructured heavy JSON serialization payloads on the server side, achieving a 25% reduction in data transmission latency and eliminating downstream client-side rendering bottlenecks.
My Projects
Projects I worked on. Each of them containing its own case study.
TurfSync
A production-grade sports arena booking and live streaming system. Features high-concurrency slot booking, multi-tenant dashboards, secure payment gateway integrations (bKash/SSLCommerz), real-time notifications via WebSockets & SMS, and automated database cleanup using Cron jobs.
Sign Vision
An AI-driven real-time computer vision system built to translate sign language into text and speech. Leverages YOLOv8 models with custom training datasets (10,000+ hand posture images), achieving a remarkable 97.4% detection accuracy for accessible communication.
Blog App AI
A full‑stack MERN Blog Application featuring authentication, blog and category management, profile updates, image uploads, rich-text editing, comments, likes, real-time chat, AI-generated content, and deployment on Vercel.
ChatApp
It is a real-time chat application built using ReactJS, Redux and Socket.IO on the frontend, and NodeJS, Express and MongoDB on the backend. The application allows users to sign up and log in to their accounts, and engage in real-time conversations with other users.
