Job Experience

I am a systems-level thinker with hands-on experience architecting, building, and securing enterprise-grade software. Below is a summary of my professional experience and key accomplishments.

DYNAMIC SOLUTION INNOVATORS

Software Engineer | April 2023 – Present | Dhaka, Bangladesh

As a core member of the engineering team, I design and build mission-critical enterprise systems for major government and public sector clients. My role encompasses the full software development lifecycle, with a strong focus on backend architecture, security, and operational excellence.

• Engineered secure and scalable enterprise Java EE applications for critical government infrastructures, translating complex offline bureaucratic processes into streamlined digital workflows.
• Acted as a key member of the internal cybersecurity team, conducting threat modeling sessions and providing guidance on secure coding practices for projects across the organization.

Key Projects

E-Appeal: Digital Appeals System for NBR & USAID

A digital platform for managing tax-related appeals.

• Pioneered the company’s first enterprise-scale JSF application, establishing engineering guidelines and architectural best practices that became the standard for subsequent projects.
• Designed and implemented a multi-layer architecture (View, Service, Repository) with a strict separation of concerns.
• Implemented a centralized RBAC security model using Jakarta Security with a custom form-based authentication mechanism.
• Integrated Java Message Service (JMS) for asynchronous, decoupled event handling (email/SMS notifications), improving system resilience.

Project Scratch: Internal Core Services Platform

An internal platform designed to accelerate development by providing reusable core services.

• Engineered a centralized observability stack using Prometheus, Loki, and Grafana. Exposed JMX metrics from GlassFish to a Prometheus endpoint for real-time application and infrastructure monitoring.
• Dockerized the complete application stack, including GlassFish, PostgreSQL, MinIO, and RabbitMQ, to create a portable development environment.
• Developed a reusable Lazy Data Model component for PrimeFaces and successfully contributed a related feature enhancement to the official PrimeFaces open-source library (PR #12865).

SHMS: Smart Hotel Management System

A nationwide licensing and registration system for hotels and restaurants.

• Contributed to the design and implementation of a generic, state-driven approval workflow engine, making the logic reusable across multiple application types and minimizing code duplication.
• Utilized Aspect-Oriented Programming (AOP) principles to cleanly separate cross-cutting concerns like notifications and auditing from core business logic.

BCIC-ERP: End-to-End Enterprise Resource Planning

A comprehensive ERP system for process automation across 12 integrated modules.

• Assumed full ownership of the Procurement module, leading its entire lifecycle from business analysis (As-Is/To-Be modeling) and database schema design to hands-on development and successful client delivery.
