Ballerina Compiler Design and Implementation

ballerina-lang

I’m currently leading the design and architecture of the Ballerina Language Compiler implementation. Before Ballerina became a fully-fledged general-purpose language, we experimented with DSL-like syntaxes, and I was a part of the compiler and runtime team from that time. After several years of dedicated development and design, we have successfully built a Ballerina Compiler that meets the needs of developers who want to write integrations. I’m proud to have played a key role in this achievement and continue to work towards improving the language and its tools for the benefit of the development community.

Ballerina Language Specification

Current Spec, 2022R4

As a primary contributor to the Ballerina Language Specification from the beginning of the language design process, I have been involved in several iterations, feature changes, re-implementations, and design verifications. Being an initial member of the Ballerina team, I have played an active role in shaping various language features and helping the team throughout the development process. I’m proud to say that our efforts have resulted in a well-designed language that meets the needs of modern integration challenges.

WSO2 Business Process Server

Carbon Business Process
Product BPS (Archived)

WSO2 Business Process Server (BPS) was an easy-to-use, open-source business process server that executed business processes written using BPMN, WS-BPEL, and WS-HumanTasks standards. As a developer and release manager of this product, I had the opportunity to contribute to its development and add various features, including HumanTask Coordination, Caching layer, and multiple UX improvements. While the product is now deprecated, I’m always happy to answer any questions you may have about it. Feel free to contact me anytime.

ODE

Apache ODE (Forked)
Apache ODE (Retired)

This repository contains the WSO2 maintained fork of the retired Apache ODE project, which was a WS-BPEL compliant web services orchestration engine. As a developer on this project, I had the opportunity to work on its development and maintenance. While BPEL has less traction now and the parent project is retired, I’m always happy to answer any questions you may have about it. Feel free to contact me anytime.

WSO2 Business Rules Server

Product BRS (Archived)

WSO2 BRS was a lightweight and easy-to-use Open Source Business Rules Server that allowed business decisions to be exposed as secure and reliable web services and integrated with an organization’s application integration infrastructure. As a maintainer and release manager of this repository, I had the opportunity to contribute to its development and maintenance. However, the product is now deprecated.

Java4BPEL Extension

java4bpel

Java4BPEL is an extension for Apache ODE and WSO2 BPS that I developed. It introduces a new BEPL extension activity that allows Java libraries to be invoked using BEPL. This extension activity enables the integration of Java code within the BPEL process flow, providing greater flexibility and customizability. I’m proud to have developed this extension and hope that it has proven useful for those using Apache ODE and WSO2 BPS.

metcat

The MetCat project was aimed at developing a metadata catalog that could be integrated with the Apache Airavata project. The project’s primary focus was on capturing metadata from workflows and assisting in scalable metadata management and user-defined queries. While the project is now deprecated, it was a valuable learning experience and an opportunity to contribute to the development of an important tool in the scientific community.
