Dhaka, Bangladesh
I’m a Senior Software Engineer specializing in distributed backend systems and platform engineering, with 10+ years of experience delivering high-scale solutions across fintech, energy, and SaaS domains. My work focuses on system design and production engineering—building services that are reliable, observable, secure, and performant at scale. I’ve led and delivered systems involving microservices, CQRS, event-driven architectures, and identity federation, with measurable outcomes such as 200x performance improvements, 85% latency reduction, and improved system reliability in real-world platforms. I have deep hands-on experience with the .NET ecosystem, including modern .NET Core, API-first architectures, Redis-based caching strategies, and cloud-native deployments on Azure and AWS. A significant part of my recent work has involved authentication and identity platforms, including Azure AD B2C ↔ Keycloak federation and secure token-broker architectures. Alongside production systems, I actively explore independent engineering projects, including AI-assisted workflows, autonomous agent coordination, and distributed memory models. These projects are exploratory in nature and focused on learning, system design patterns, and developer productivity—not marketing demos or research hype. I’ve worked extensively with remote, cross-timezone teams and value environments that emphasize ownership, thoughtful system design, and real-world problem solving over algorithmic theatrics. Currently open to senior backend or platform engineering roles in remote-first teams.
Independent Engineering Projects AI Multi-Agent SDLC Automation: Built autonomous agent workflows using LangChain and OpenAI APIs to explore automated requirements analysis, bug triage, and QA orchestration. Focused on engineering productivity and agent coordination patterns rather than production deployment. Recall Forge — Distributed Memory Engine (In Progress): Designing a generic, distributed memory layer for multi-agent systems, supporting shared context, isolation boundaries, and long-running workflows. Exploring hybrid RAG approaches (vector + graph) for durable reasoning state.
Architected and delivered a secure identity federation platform bridging Azure AD B2C and Keycloak, using a BFF token service with Redis-based caching. Led the migration of revenue modeling from Excel-based workflows to an API-first, cloud-native platform using MongoDB and PostgreSQL. Built internal automation and Power Platform integrations, reducing operational overhead and manual processes. Resolved 15+ critical production issues, improving SLA compliance and reducing system downtime by approximately 25%.
Designed reusable performance optimization frameworks using LazyCache, applying Decorator and cache-aside patterns across multiple backend services. Improved API request-response latency by ~85% through asynchronous I/O and system-level optimizations. Maintained 98% test coverage through unit and integration testing, ensuring resilient CI/CD pipelines and safe production deployments.
Re-architected high-volume data access paths using CQRS with Redis and Dapper, achieving ~200x query performance improvement and enabling horizontal scalability. Built event-driven microservices using Kafka and developed real-time analytics pipelines with TimescaleDB and Grafana. Delivered BI and analytics solutions that improved sales and marketing effectiveness by approximately 25%.
Developed custom Microsoft Dynamics CRM plugins, workflows, and scheduling APIs using C# and JavaScript. Led end-to-end CRM migrations, consolidating legacy systems into unified platforms with zero data loss. Automated internal delivery workflows, improving engineering efficiency and reducing manual errors.
