About Affan Ahmad

I’m a passionate software engineer with a strong focus on backend development, distributed systems, and performance optimization. I recently took ownership of the Unified Messaging Service (UMS), where I led major improvements using Apache Flink and Apache Beam — including the implementation of ParDo, PTransform, custom pipelines, and integration with sharded databases.I resolved critical issues in Beam’s Pub/Sub transform with a custom wrapper, enhanced performance in our email service by optimizing the Apache HTTP client, and worked collaboratively to reduce async latency. I also delivered the V3 subject line feature for LC Atreides and implemented the Outbox functionality with supporting Akka batch applications and GCS/service account infrastructure updates.On the full-stack side, I’ve built and integrated chatbots using Dialogflow to troubleshoot QoS, SIP, and branch connectivity issues. I\'m trained in HTML, CSS, React, JavaScript, Java (Spring), Python, and multi-threaded POSIX C programming. My systems knowledge includes building a Linux memory manager in C for custom allocation/deallocation monitoring.As a competitive programmer, I hold a 5-star rating on Codechef, and placed 1st and 2nd in two developer contests on Topcoder.Always excited to tackle complex problems, learn fast, and build high-impact systems
