As the title of this site says, I’m a seasoned software engineer with a professional journey spanning back to 2004. Throughout my career, I’ve delved into a multitude of projects and companies, honing my skills across various technologies. While my primary expertise lies in Java development, I’ve also ventured into diverse areas such as mobile web projects, where I’ve tackled tasks like crafting solutions in Wireless Markup Language (WML) for mobile websites and mastering the intricacies of HTTP for SMS gateways. Or ActionScript and flash for preparing some banner.
Consider me a full-stack developer; I’m well-versed in all aspects of software development, from crafting intuitive user interfaces to optimizing backend performance and managing databases. With a knack for designing and delivering N-tier applications, Java has been my trusty companion, although I’ve dabbled in .NET on occasion.
I have extensive experience across backend, database, server-side development, UI, UX. As a Linux enthusiast, I’ve enjoyed coding on Linux systems since 2008, leveraging its capabilities for various projects. My encounters with challenges often involved the database layer, where I’ve honed my skills in fine-tuning kernel parameters, especially related to networking and TCP, for optimal performance. Additionally, I am also ‘JVM bender’ through my adeptness in configuring Oracle and IBM JVMs, particularly during the J2EE era with WebLogic and WebSphere, and more recently with OpenJDK, Tomcat, and Spring Boot.
Below is a list of the tools/libraries and platforms that I’ve worked with so far.
