ABOUT HOJJAT ABEDI

Seasoned Full Stack Java Developer (16+ years) based in Leipzig, Germany, with a deep passion for architecting and building resilient, scalable cloud-native applications and microservice ecosystems. My journey in software development has been one of continuous learning and adaptation, from foundational web technologies to leading complex projects in demanding sectors like Fintech, Stock Trading, and Banking.My career began with crafting client-centric websites and mastering web fundamentals. This evolved into developing robust enterprise Java solutions, where I honed my skills in demanding financial environments—tackling challenges in security, performance, and system reliability. As a Lead Developer in the Fintech space, I spearheaded the creation of an e-wallet platform, including its core microservices and security architecture using Keycloak and OAuth2.I thrive on solving complex technical challenges and optimizing system performance. Notable achievements include: Drastically improving database query speeds (reducing 10-minute operations to just 15 seconds). Resolving critical production stability issues in Spring Boot services by meticulously tuning JVM parameters and optimizing large data processing (e.g, reducing ~1GB API response memory usage to manageable levels, eliminating OOM errors in Kubernetes). Engineering event-driven architectures with Kafka and Azure Event Hubs, and deploying highly available identity solutions on Azure Kubernetes Service (AKS) using custom Helm charts and Pulumi for IaC.My technical toolkit is centered around Java, Spring Boot, and Spring Cloud, complemented by extensive experience with microservices, cloud platforms (AWS & Azure), Kubernetes (AKS), Docker, and a suite of DevOps practices including CI/CD with GitHub Actions/Azure DevOps. I\'m proficient in building secure REST APIs, leveraging databases like PostgreSQL, MySQL, and MongoDB, and have also delivered Python/Flask microservices and engaging frontends with Vue.js. As an AWS Certified Developer - Associate, I\'m committed to cloud best practices.I believe in a TDD-driven approach to ensure code quality and maintainability. I enjoy collaborating with cross-functional teams, refining requirements, and mentoring colleagues. I\'m always excited by opportunities to leverage my expertise to build innovative, impactful software and contribute to a forward-thinking team.Open to connecting and discussing challenging roles in cloud-native Java development!
