Full-stack engineer building AI-native systems for the web.

I'm Mukesh Kumar Thakur — building AI systems for healthcare revenue cycle at RapidClaims. I design architecture, wrangle data pipelines, and make interfaces feel lightweight — recently cutting a front-end from 2 GB → 400 MB.

01 / About

Engineer by craft. Architect by instinct.

I care about the seam between infrastructure and interface — where performance meets polish. Over the last two years I've designed AI enrichment pipelines, rebuilt memory-leaking dashboards, and shaped the architecture for whole product modules from first commit to production.

Outside of shipping at RapidClaims I'm building an MCP marketplace — a natural-language control layer over Gmail, Calendar, Tasks, and Slack.

Where I've shipped lately.

Software Engineer

RapidClaims Aug 2026 — Present
  • AI-powered revenue cycle automation for healthcare — software that improves medical coding accuracy and reduces claim denials.
  • Full-stack across the product: Python/Django services, Temporal workflows, MongoDB, and a React/Next.js front end.
  • Own features end to end — from the plan and data model through UI, tests, and review.

Full Stack Developer

Richpanel Sep 2023 — Aug 2026
  • −80% memory footprint. Reduced front-end consumption from 2 GB+ to 400 MB.
  • Real-time AI enrichment pipeline labelling every customer–agent conversation with intent & sentiment.
  • Gmail → Richpanel sync pipeline — scale-agnostic ingestion of any mailbox into Richpanel as tickets; backfill + live stream, deduped and threaded.
  • Returns platform — end-to-end architecture with automated label generation and workflow orchestration.
  • Owned multi-module system design across Nest.js, Vue.js, MongoDB, DynamoDB, PostgreSQL, and Neo4j.

Things I've built & what I learned.

/ai-assistant 2025

AI Personal Assistant

MCP marketplace + chatbot that speaks natural language to Gmail, Google Calendar, Tasks, and Slack. Multiple MCP servers, secure auth, automated workflows.

/gmail-sync Richpanel

Gmail → Richpanel Sync Pipeline

Scale-agnostic sync that ingests every message from any Gmail mailbox into Richpanel as a ticket — backfills decade-old inboxes and streams new mail in real time, fully deduped and threaded. Mailbox size is no longer a ceiling.

/ai-enrichment Richpanel

Real-time AI Enrichment Pipeline

Streams every customer–agent conversation, classifies intent & sentiment, writes back to the product surface in near-real-time.

Extensions, packages & apps anyone can use.

/html-to-markdown Chrome Web Store

HTML to Markdown Clipper

A visual element picker for any webpage — hover, click, and the element lands in your clipboard as clean Markdown. A full HTML parser runs locally: headings, inline styles, links, images, fenced code with language detection, tables, nested lists, blockquotes. No servers, no API keys, zero data collected.

Chrome ExtensionManifest V3JavaScriptZero-config
/quick-shortcuts npm

Quick Shortcuts

A Vue 3 + TypeScript component that drops a command palette into any app — keyboard-first search across the actions that matter, so users reach them without hunting through menus. Published to npm with full docs.

Vue 3TypeScriptnpmUI Package
/password-vault 2026

Password Vault

A password manager that never leaves the machine. Shortcut autofill, save-on-login, and Touch ID unlock via the WebAuthn PRF extension — the Secure Enclave returns a secret that wraps the vault's AES key, so the wrapped key on disk is useless without the authenticator. No account, no sync, no servers, no dependencies.

Chrome ExtensionManifest V3WebAuthn PRFAES-GCMZero-dep
/react-if-directive npm

React If Directive

Conditional rendering as attributes — r-if, r-else-if and r-else sit on the element itself instead of nesting ternaries inside JSX. A Vite plugin rewrites them to standard React at build time, so nothing ships at runtime, with an ESLint plugin that flags broken chains in the editor and TypeScript types for autocomplete.

/radar radar.kryl.dev

Radar

A tech-signal reader with a bar for entry. Every night it sweeps ~50 hand-picked engineering sources, has an LLM score every item against a curated interests profile, and serves only what clears the bar — each item with a two-sentence tldr. Multi-user accounts, topic filters, and votes that teach the ranking.

React 19ConvexTypeScriptLLM RankingNetlify
/rawlens rawlens.kryl.dev

Rawlens

Raw files, readable at last — Markdown, JSON from any API response, and CSV open as clean documents instead of walls of text. A collapsible JSON tree that keeps 64-bit ids exact, search that finds matches inside collapsed nodes and shows each record whole, sortable CSV tables, twelve themes. Hand-written parsers, no dependencies, not a single network request.
