Ballerina is a programming language designed for network distributed application development. Ballerina developer tooling provides a numerous set of tools including CLI tools, compiler extensions, language plugins, IDL extensions, etc. As an associate technical lead, I have been playing the following primary roles.
1) Role of lead engineer - Responsible for developing the Ballerina debugger and semantic versioning validator tool.
- Mentor an intern project to introduce the semantic versioning validator CLI tool for Ballerina language, which prevents pushing packages to Ballerina central with Semver incompatible changes.
2) Role of Ballerina Dev tooling team lead - Responsible for overall output of a 6-member team.
- Provide technical leadership for the design and the implementation of Ballerina OpenAPI converter tools
- Conduct architectural and code reviews for the components that resides under Ballerina tooling
3) Role of Engineering Manager - Responsible for quality of work, deliverables of a 8-member team
- Identify bottlenecks in the process and roadblocks to success of my team and clear the roadblocks

Ballerina is a programming language designed for network distributed application development. Ballerina developer tooling provides a numerous set of tools including CLI tools, compiler extensions, language plugins, IDL extensions, etc. As a senior software engineer, I have contributed to the Ballerina compiler and developer tooling with the below contributions.
- Design and implement a LSP(Language Server Protocol) client library called 'LSP4IntelliJ' for Jetbrain IDEs, which received a massive community attraction and currently being continued as a community-driven open source project under the official Ballerina Platform GitHub Organization.
- Design and implement the debugger tool for the Ballerina language from scratch, with the support for conditional Breakpoints, logpoints, stepping (in/out/over), stacktrace view, variable view, watch window, expression evaluation support, etc.
- Optimize Ballerina compiler to reduce the jar creating time by 10x using Ballerina JAR compression + creation related optimisations.
- Initiate the effort to create custom JREs for Ballerina runtime.

Semantic Versioning Validator tool for Ballerina packages
Jan 2022 - Present
Semantic versioning is a well-known and widely adopted concept in the software world, mainly to overcome the problem of dependency hell. Currently the Ballerina package/library versioning strategy is also based on the semantic versioning specification.
However, Ballerina library developers are able to change the version of their Ballerina packages at will, because the Ballerina platform itself currently does not provide any validation/enforcing mechanism to ensure the semantic versioning compliance between consecutive package releases. This may result in releasing new versions of packages that are not semver compatible. As a solution to the above problem, I've contributed to the Ballerina eco-system with the below contributions.
- introduce a specification which defines the semver compliance for Ballerina APIs.
- implemente a utility tool which will inform the user if the API changes conform to the new package version that the user is trying to build.

Debug server for Ballerina Language
Mar 2020 - Present
Ballerina is a statically typed, compiled programming language designed for network distributed application development. Ballerina debug server provides the debugging capabilities to the Ballerina language via its language extensions, i.e. VSCode and Intellij plugins.
LSP4IntelliJ: The most comprehensive language client library for IntelliJ plugins
Jan 2020 - Present
Lsp4IntelliJ is a client library, which provides language server support for IntelliJ IDEA and other IntelliJ-based IDEs. I initiated this project as a requirement for the Ballerina Intellij plugin and then moved as a standalone language client library for all the IntelliJ IDEs.
Due to the massive community attraction, its currently being continued as a community-driven open source project under the official Ballerina Platform GitHub Organization.
