About

I hold a Bachelor of Technology in Electronics and Communication Engineering from Kerala Technological University, graduating with a CGPA of 8.3. During my college years, I also served as the Secretary of my Department Association, where I developed leadership and organizational skills. Alongside academics, I enjoy doodling, cooking, photography, and traveling, which keep me creative and motivated. I have 6+ years of professional experience as a Software Engineer in the airline and travel industry, with expertise in Java, Spring Boot, microservices, gRPC, Docker, Kubernetes, AWS, Redis, and Kafka. I started my career at IBS Software, where I migrated legacy monolithic systems into microservices. At UST Global, I contributed to building a Kafka-based communication engine. Currently, at Verteil Technologies, I design and maintain scalable backend microservices, optimize airline booking workflows (OrderCreate, OrderRetrieve, OrderChange), enhance monitoring with Prometheus/Grafana, and improve overall system performance. My key strengths include problem-solving, debugging, performance tuning, teamwork, and adaptability. 📞 Let’s connect! You can reach me at +91-9747662928, email me at gokul.am.kr@gmail.com .

Software Engineer

Nov 2022 – Present · 3 yrs 6 mos · Kochi, Kerala, India

Designed and developed backend microservices in the airline distribution domain using Java (17/21), Spring Boot, and Gradle, powering search, booking, and order management workflows.
Implemented core workflows such as OrderCreate, OrderRetrieve, OrderChange, and asynchronous cancellation handling, ensuring reliability and fault-tolerance across distributed systems.
Built and optimized the Offer Stitching process, enabling multiple airline offers to be combined into a single booking flow. This involved parallel OrderCreate requests, response merging, failure handling with void/cancel APIs, and delivering seamless end-to-end booking experiences.
Enhanced connector services by integrating SOAP/REST APIs and optimizing request/response handling, reducing latency and improving throughput under high load.
Optimized system performance by implementing HTTP connection pooling, SOAP parsing improvements (DOM → Axiom/StAX), and capturing heap/GC metrics for debugging and tuning.
Integrated monitoring and observability with Prometheus/Grafana, customizing dashboards for JVM, connection pools, and transaction performance metrics.
Performed load and performance testing with k6, benchmarking RPS, throughput, and memory usage to ensure system scalability under airline transaction volumes.
Automated CI/CD pipelines for microservices on AWS EKS and Kubernetes, reducing deployment time and improving delivery reliability.
Collaborated closely with product and QA teams to debug production issues, implement pricing rule augmentations, OB Fee workflows, and validate transaction history, ensuring smooth airline retailing experiences.
