I am freelancing for development, maintenance and consultancy of all sorts of Java and/or JavaScript based web applications. I can also very fast turn UI designs into plain HTML/CSS with proper UX and accessibility. I am a solid analyzer who can quickly nail down root causes of any software problems/bugs and find proper solutions, including performance issues. I am a keen critical thinker who strives to find and implement real solutions rather than patches or work arounds. I am self-employed and only available for Corp-to-Corp contracts. Send me a message here in case you are interested!

After that I have helped and consulted in improving the build pipeline scripts, cleaned up the tech debt by refactoring away more than half of source code (~140k loc became ~60k loc), fixed performance issues by optimizing the efficiency of business logic, implemented a couple of JUnit/Mockito/Selenium tests with a custom Docker/TestContainers image, and implemented a new dashboard screen with reactive charts and statistics.

Germania Insurance is a insurance provider. I have helped to adjusting an end-of-life JSF 1.2 web application originally built by Ant and running on WAS5 (which went EOL as to IBM support) to be built by Maven instead and to be able to run on WAS9 (with continued IBM support) with an absolute minimum of source code changes. I also wrote Jenkins build/deploy scripts in Groovy and I have maintained the Android side of a React/Ionic/Capacitor based mobile application to add some new functionality. I have also implemented Okta based authentication in both the JSF and React based applications, which is tested by JUnit/Mockito/Mocha with a custom Docker image.

MyTutor is an online tuition service. I have migrated the web application from JSF 1.x + RichFaces 4.x to JSF 2.x + PrimeFaces and on the fly improved its memory usage, performance and scalability. SQL queries and DDLs were also analyzed and optimized. Memory usage dropped over 70% and page loading speeds improved from seconds to subseconds. An Amazon S3 based CDN was used whereby logic was written to automatically combine and sync all the CSS/JS resources. The CSS was also completely rewritten to be fully and fluently responsive across all screen sizes whereafter the distinct ‘mobile version’ was dropped to eliminate the unnecessary maintenance burden. I have reimplemented the SagePay payments functionality to use a REST API instead of an iframe. Further I have also developed a timezone-aware schedule which was used by tutors and students all over the world. All the things were tested by JUnit, Selenium and Arquillian with a custom Docker/TestContainers image.

The web application ran at WebSphere/J2EE. I was tasked to change the HTML markup and CSS style of the front end from an older IBM layout to a newer IBM layout. Partly I have also changed and added some new JSP/Servlet based functionality to the web application. Furthermore I also wrote a bunch of prototyped HTML pages and use cases and I did lot of system tests.

IBM HONE/LINK department grants support to owners of an IBM server. The owners can request, review, change and order hardware and software configurations of their IBM server using several web applications. Those web applications ran at S390 servers with zVM OS and are been programmed in legacy REXX. Those web applications can process XML as well as HTML as input and output. I was responsible for maintenance of those web applications. At Q2 2003 IBM decided to move the front-end of those web applications from REXX to WebSphere/J2EE, while the back-end still remains REXX. The new J2EE front-end would temporarily communicate with the legacy REXX back-end using SOAP web services. I was involved in writing JSPs and a bunch of XSLTs which transform XML to JSP for the new J2EE front-end. Before leaving the department I have educated and supported three Indian developers who were about to take over my activities.
