I build small, well-documented systems end to end — data, model, API, UI, deployment — and contribute fixes to the open-source tools I use. Analyst at Accenture; previously a computer vision intern and open-source contributor. I care about honest evaluation, reproducible fixes and maintainable tooling.

• MCP security & AI infrastructure — Vexar-MCP (static analysis, SARIF, policy gates for CI) and vexar-autofix
• Agentic payments — Grace: judging an agent's spend against the business's own PayPal payment history instead of a static ceiling
• Machine learning & computer vision — object detection, auto-labelling, model cards and honest evaluation
• Research & systems code — maintenance fixes in large, unfamiliar codebases (ML research, shader transpilers, developer tools)
• Building in public — every project below ships with docs, tests or a live demo, and states its limits clearly

For research and notebook projects, read their data and evaluation limitations before interpreting metrics. Contribution status below distinguishes merged work from PRs still in review; an open PR is not an endorsement by its upstream organisation.

• Reproduce first, patch second — every fix starts from the failing case, not a guess
• Smallest defensible change — focused PRs a maintainer can actually review, with tests/conformance runs where the project has a harness
• Review-friendly — I stay on the PR thread until it's merged or closed; the fastest way to reach me is right there

Core: Python (pandas, NumPy, scikit-learn, PyTorch, TensorFlow/Keras, OpenCV, FastAPI) · JavaScript/TypeScript (React, three.js, Vite) · C++ · SQL

MLOps & infra: Docker · Git & GitHub Actions · MCP (Model Context Protocol) · Kubeflow · Jupyter / Google Colab · Linux

AI security & agents: static analysis (AST-based scanners, SARIF, policy-as-code CI gates) · LLM agents on NVIDIA Nemotron via Nebius Token Factory · PayPal Orders API sandbox

Via open source I also read and patch code in Go, Java, Rust and shader languages (GLSL / HLSL / Slang / WGSL) when the project calls for it.

_{Top languages counts only my own repositories — the updater automatically excludes my forks of large upstreams (VS Code, Ghidra, Google Research, …) so the chart can't be skewed by other people's code.}

Ranjith Rosan maintains the original projects linked on this profile and contributes to other open-source projects. Each repository documents its purpose, setup and limitations; upstream contribution status is shown separately from project ownership.

LinkedIn · open an issue on any repository above — I reply. If you're a maintainer reviewing one of my PRs: thank you, and the fastest way to reach me is right there.

_{Curious how this page maintains itself? docs/AUTOMATION.md explains the 2-hourly updater, its honesty rules, and how to reuse it.}
