Mizanur Rahman Hridu
Senior Full Stack Software Engineer
Hi, I'm a Senior Software Engineer with over 4+ years of experience building scalable backend systems using .NET technologies.
Throughout my career, I've worked across the Online Travel, Food Delivery, Recruitment, and Logistics domains, focusing on backend development, microservices, distributed systems, and third-party API integrations.
Currently, I'm working at TechnoNext Software, a concern of the US-Bangla Group, where I develop a multi-tenant Online Travel Agency platform serving multiple travel brands. My work includes building scalable backend services, integrating airline and GDS/NDC APIs, and developing business-critical features. One project I'm particularly proud of is an automated booking cancellation service that significantly reduced airline ADM penalties for multiple clients.
I've also contributed to Foodi by developing customer engagement automation features and built a fare intelligence platform that helps airlines make data-driven pricing decisions.
Previously, I worked at Bdjobs.com, where I helped modernize legacy systems and improve job search performance using Angular, ASP.NET Core, and a CQRS-based architecture. Earlier, I worked remotely at E-Desh Limited, contributing to a logistics platform by building backend APIs and optimizing application performance.
Beyond my day-to-day work, I enjoy learning new technologies, solving real business problems, and mentoring junior engineers. I'm always looking for opportunities to build reliable, scalable software that delivers measurable business value.

In-depth looks at problems I've solved and how I solved them

How a Redis Stampede (Thundering Herd) Hit Our OTA Search Ranking Engine — And How We Fixed It
When 30 integrated suppliers and 40-50 unique airlines per search met an uncached rank lookup, concurrent cache misses stampeded the database in unison — here's how negative caching and locking around retrieval broke the herd.

How I Made My Static Website Editable — Without a Server or Database
This portfolio site is hosted completely free with no server behind it. Here's how I still gave myself a private dashboard to update every part of it from a browser, without adding a server or a database.

Progressive Search: Showing Flight Results Before All 30 Suppliers Answer
Flight search used to wait on all 30 suppliers before showing anything — one slow responder meant everyone waited. Here's how Server-Sent Events let us stream results the moment each supplier answers.
