Principal engineer who still loves shipping—Rails, React, and AI that actually ships.
I've spent years on high-traffic monoliths and fintech rails (literally)—now I care most about boring reliability + sharp AI tooling. If you want someone who reads diffs and docs with equal enthusiasm, we'll get along.
What I'm exploring
I believe the most interesting engineering today happens where mature Rails systems meet LLMs—not as a rewrite, but as careful augmentation: retrieval, guardrails, and tools that fit how teams already ship. Right now I'm deep on RAG patterns, vision APIs for structured extraction, and developer-facing extensions that make AI feel boringly reliable.
I'm a principal engineer based in Noida, Uttar Pradesh. The résumé bullets live in Experience—here's the short version: I like hard problems on mature stacks, clear ownership, and teams that still care about tests when nobody is watching.
Lately that means RAG and LLM integrations alongside Rails and React, cutting AWS spend without drama, and mentoring so code review stays kind and useful. I ship side projects and OSS when an idea won't leave me alone—see Projects for the ones I'm proudest of.
Outside tickets and PRs: I read release notes, tinker with extensions, and write notes when a pattern feels worth writing down—even if it's just a few paragraphs.
Formal employment—roles, scope, and outcomes. For independent builds and OSS, jump to Projects.

Things I build on my own time—tools, experiments, and small products. For day-job impact and timelines, see Experience.
Featured work below; the rest lives on GitHub with the same care for READMEs and reproducible setup.
RAG chatbot with LangChain, Chroma, and Gradio—semantic retrieval and Q&A over domain documents. A playground for grounded answers and vector search patterns I reuse in production tooling.
Full-stack receipt parsing: NestJS API, BullMQ workers, React/Vite UI, and OpenRouter vision models. Upload an image, get structured vendor, line items, and totals—real-world LLM extraction with queues and storage.
Chrome extension that brings GPT-powered review to Bitbucket pull requests—fast feedback on diffs without leaving the host. Built for teams that live in Bitbucket, not GitHub.
Grok in the browser—Chrome extension for Grok API access across the web.
Decode sourcemaps and map minified stack locations back to original source.
VS Code extension: Procfile-style processes, one terminal, Foreman-style prefixed logs.
Short write-ups—things I've learned building with AI and shipping serious money paths. Full long-form posts may follow; for now, here's how I think in public.
Start with the question your coworkers actually ask, not the embedding model leaderboard. Chunking, metadata, and a boring evaluation loop beat clever prompts. At work we paired OpenAI embeddings with Chroma and tight feedback from editors—semantic search only matters if humans trust the first page of results.
Money teaches you that “it works on my machine” is never enough. Idempotency keys, audit trails, and treating third-party APIs as flaky by default matter more than framework debates. The win was boring: exhaustive tests, clear ownership on incidents, and never shipping a payment path you couldn’t explain to compliance.
Monoliths that already handle auth, billing, and domain rules are an asset. I’d rather wire an LLM behind a small service boundary—with Zod-shaped outputs and human review—than chase a greenfield rewrite. The intersection I care about is product velocity with safety rails, not replacing Ruby with buzzwords.
I'm always open to discussing new projects, creative ideas, or opportunities to be part of your visions.
