About Me
I’m a software engineer who enjoys building things end-to-end. Most of my work sits at the intersection of software engineering, distributed systems, and data.
I like learning out loud by experimenting and building from first principles, whether it’s a freelance website, a code-flow visualizer, a performance-testing framework, or even my own mini-database.
I work on Watsonx.data at IBM, where I’ve built CLI platforms, backend services, performance tooling, and internal PoCs across the stack. I studied Computer Science at IIIT Kottayam, where my curiosity for systems and engineering really took off.
Outside work, I love exploring half-baked ideas, turning them into real personal projects, and writing about what I learn along the way hoping the pain points I solve resonate with other developers and users.
Experience
- Led migration of a legacy Docker CLI to a modern plugin-based CLI platform while integrating V3 APIs across multiple internal services and preserving backward compatibility, reducing average setup time by 50%
- Added automated execution of table maintenance and Spark job commands using PySpark, collapsing a 6-step manual workflow into a single command reducing execution time by 70%
- Designed an automated performance testing framework for the access-control layer using PyMilvus, PyIceberg, and Presto Python client, enabling unattended 10–12 hour benchmark runs and eliminating manual query execution and result collection
- Improved logging and diagnostics for the central metadata service, reducing log noise by 20%
- Delivered PoCs including Text-to-Milvus Query using RAG workflows (LangChain + Watsonx AI), Postgres Arrow Flight Extension setup, and S3 authentication testing for internal services
- Collaborated with 10+ internal teams across Watsonx.data along with delivering various knowledge transfer sessions, technical demos, and release presentations
- Took complete ownership of end-to-end CLI development in Golang, including setup, documentation, testing, troubleshooting, bug fixes, backend enhancements and developer support
- Took ownership for resolving all Translation related issues in Watsonx.data UI spanning across 7 languages eventually improving the cross-language consistency.
- Spearheaded the UI enhancements to support Google Cloud Storage in Watsonx.data with cross-team collaboration efforts
- Shipped 10+ UI features and various bug fixes across the product contributing to monthly releases using ReactJS, Carbon, IBM Cloud, Google Cloud Storage and internal Watsonx.data tools
- Spearheaded the Frontend redesign of the TradeCops Website with complete ownership and end-to-end implementation of multiple new features and enhancements
- Developed various reusable UI components using ReactJS while maintaining responsiveness across all devices
- Implemented smooth animations using the GSAP Animation Library
- The website achieved a 100 SEO score on Lighthouse
Projects
- Developed a tool that generates interactive call-graph visualizations to identify entry points in a codebase and trace function flows
- Uses DFS based Graph Analysis to detect entry points in a codebase reducing the manual code navigation effort by 30%
- Employs modular AST Parsing to breakdown the function flow and Tree Sitter Library for supporting codebases of multiple languages
- Contains a single-run quick-setup bash/shell script along with Github API support for fetching code files directly from Github
- Added various tests using Python Pytest library
