Senior Software Engineer | Trading and Enterprise Systems, Dhaka

Feroz Ahmed builds the quiet systems software runs on.

I am a software engineer and team lead in Dhaka with 10+ years experience building large, regulated, high-integrity systems in Java and Spring Boot. My expertise includes integrating with exchanges using FIX 5.0 SP1 and Nasdaq ITCH (DSE-INET), and I am currently implementing for CME Globex iLink 3 and MDP 3.0. As a Product Owner and technical lead, I have guided teams through complex exchange certifications and delivered robust backend solutions.

My current focus

Building intelligent systems that connect language models to real-world APIs via Google Cloud.

I am actively engaged in engineering the infrastructure that enables large language models (LLMs) to interact with and control external systems. This involves developing custom REST APIs, exposing them securely to GCP Model Context Protocol (MCP) servers, and building robust MCP clients. My work focuses on intelligent routing for chat and voice commands, ensuring LLMs can dynamically select and utilize the correct APIs to achieve complex tasks within a controlled and observable environment. I leverage GCP's managed services and agent-based deployments for observability and operational efficiency.

Selected work

A few systems I designed, led, or rebuilt from the inside out.

AI Knowledge & Tooling

MCP-connected knowledge system for e-Government APIs

Led research and development for a knowledge system for government projects with private domain knowledge. I connected Model Context Protocol (MCP) servers to expose government APIs (Trade License, National ID, Tax Clearance) as callable tools for LLMs like Claude. Built a retrieval-augmented generation (RAG) pipeline over a vector database using cosine similarity for relevant document lookup. Presented the system to e-GP stakeholders.

Designed and led the development of PQcal, an Order Management System for equity and derivatives trading. For the Dhaka Stock Exchange (DSE-INET), I integrated with Nasdaq X-stream via FIX 5.0 SP1 and processed Nasdaq ITCH market data. For CME Globex, I implemented iLink 3 order entry (FIXP over binary SBE) and MDP 3.0 live feed (SBE multicast). Currently driving CME AutoCert+ certification.

Identity & Access Management

Migrating off Keycloak to a custom Spring Authorization Server

Led the successful migration from Keycloak to a custom-built Spring Authorization Server, achieving approximately 40% infrastructure cost reduction. Implemented OAuth2 and OpenID Connect for single sign-on across more than five applications. Delivered comprehensive IAM training and architectural documentation in Uzbekistan, ensuring smooth adoption and robust security.

Experience

Where the work above actually happened.

Feb 2016 - Present
Dohatec New Media
Dhaka, Bangladesh
Product Owner, Team Leader, Senior Software Engineer

Throughout my 10+ years at Dohatec New Media, I have advanced from Software Engineer to Product Owner and Team Lead, overseeing teams of up to 10 developers. My contributions span a variety of large-scale, high-integrity systems.

As Product Owner and Software Engineer for Trading Systems (Jan 2023 - Mar 2026), I led the full requirements and architectural design for an Order Management System. This involved deep dives into FIX 5.0 SP1 and Nasdaq ITCH specifications for DSE-INET, leading a team of 10 through certification, and implementing CME iLink 3 and MDP 3.0 for a derivatives OMS (PQcal Global).

As Team Leader and Senior Software Engineer (Feb 2016 - May 2026), I was a core architect for the Bhutan e-Government Procurement (e-GP) platform, developing event-driven microservices with Spring Cloud, RabbitMQ, and integrating national digital identity for secure login. I also contributed to the Electronic Construction Permitting System (ECPS) in C#/.NET and developed a biometric system for the Anti-Terrorism Unit.

Across these roles, I have been responsible for architectural decisions, ensuring code quality, managing CI/CD pipelines, and engaging with international stakeholders.
