About

Hi there! I am Brijesh Senior Full Stack Developer with 9+ years of experience delivering scalable solutions across Banking, Logistics, and Travel domains. 💡 Currently at Zalando SE, Europe’s leading online fashion platform, I have played a key role in optimizing warehouse processes and developing microservices using java, spring boot, kubernetes, postgres and aws. My contributions have propelled Zalando toward key operational goals, including: - €5.26M+ in annual cost savings across multiple features and process optimizations. - A 40% boost in warehouse pick productivity through the rollout of automated microservices. - Reduction of order delivery timelines by 1 full day through system improvements. I also led a team of engineers through a successful Spring Boot 3 and Java 21 migration, paving the way for GraalVM and virtual threads. As the top GitHub contributor (2K+ commits/year), I’ve driven code quality, smoother releases, and strong collaboration. I also mentor junior developers, boosting their growth and team productivity during complex transitions. Past Roles: At PDGC, I engineered microservices using Java, Spring Boot, Golang utilizing concurrency and conducted POCs for real-time video services with WebRTC, strengthening the platform's scalability and performance monitoring with Grafana and Prometheus. At TCS (serving ABN AMRO Bank), I spearheaded modernization efforts by replacing legacy mainframe systems with Spring MVC REST APIs, resulting in substantial cost reductions. I boosted search performance by 50x with Elasticsearch, and cut service creation time by 90% using Node.js and Yeoman. I also integrated machine learning (Python, scikit-learn) for risk predictions, improving stock handling decisions. Key highlights of my technical expertise include: Backend: Java, Spring Boot, REST API, Microservices, Distributed systems, data structures, algorithms Frontend: VueJS, Typescript, Angularjs, Nodejs Cloud & DevOps: AWS, Kubernetes, Jenkins, Docker Databases: PostgreSQL, Mongodb, IBM DB2, Elasticsearch, Redis Testing & Automation: Selenium, JUnit, Locust Recognized for multiple awards, I thrive in Agile environments, mentoring peers and solving complex system design problems. I am always eager to discuss software engineering best practices, cloud architectures, or explore innovative solutions to drive business impact. Let’s connect if you’re interested in collaborating!
