Muhammad Sadrul Muttaquin Hoque Najat

I am a Software Engineer with over 6 years of professional experience building and operating production-grade software systems across fintech, SaaS, government, and consumer technology domains. My primary expertise is in backend and full-stack development, with a strong focus on scalable system design, workflow automation, and cloud-native architectures.

I currently work as a Software Engineer II at MarginEdge (2025–Present), where I develop fintech systems that support 10K+ restaurant clients. My responsibilities include building ACH payment collection services, integrating Zuora for automated billing and invoicing, and implementing compliance-critical billing features. I mainly work with Java, Spring Boot, AWS (Lambda, SQS, DynamoDB), React, and TypeScript, collaborating closely with product, finance, and compliance teams to deliver reliable and auditable solutions.

Previously, I worked as a Software Engineer at Dynamic Solution Innovators, contributing to large-scale government and enterprise SaaS platforms. I architected and implemented an approval workflow system used to license and regulate 100K+ hotels and restaurants nationwide. I also helped build a Recruitment Management System from scratch, digitizing recruitment tests and workflows and reducing manual paperwork by approximately 80%. My work involved Java, Go, JEE 10, Node.js, Next.js, PostgreSQL, MongoDB, GraphQL, Kafka, and PrimeFaces.

Before that, I spent over 3 years as a Senior Software Engineer at Samsung R&D Institute Bangladesh. I worked on consumer and platform products including the Windows Galaxy Buds application and Samsung DeX, where I delivered major UI components, improved automated test coverage, and resolved critical production issues. I also passed the Samsung Software Competency Test (Professional Level).

I offer backend and full-stack development services and have a proven track record of delivering scalable, maintainable, and business-critical systems in real-world production environments.
