Software Engineer at Halma plc
Full-Stack · LLM Systems · MERN · MEAN · Flutter · Python
I build web platforms, cross-platform apps and LLM systems — from the database to production release.
I'm a full-stack engineer at Halma plc, building the whole path: PostgreSQL schemas and NestJS services at the back, Kafka and Redis in the middle, Angular and Next.js dashboards at the front, and Docker and Kubernetes underneath.
The half I'm most interested in right now is AI in the engineering loop — I've built a custom LLM agent harness and n8n automation my team uses daily, and I work with RAG, vector search and agentic frameworks like BMAD and GSD. Not models: systems. The other half of my work is hardware-facing. I'm the primary developer on SyncIT, the platform that manages Sensit's gas-detection instruments over BLE, Wi-Fi, LAN and serial, on Android, iOS and Windows from one Flutter codebase.

Everything public lives on github.com/Dhairya-007. Live demos are linked where they're deployed.
A typed agent harness for Claude. The loop is the easy part — this is the rest: tool inputs validated before they run, approval gates over parsed arguments, a context budget that clears old tool output, and a verification pass that can send the model back.

Grounded document Q&A. Hybrid BM25 and dense retrieval fused by rank, a NestJS API and a Next.js UI. Retrieval is a tool the model calls repeatedly, not a prompt prefix — and an answer that cites nothing is rejected and sent back.
52 tests
A Python pipeline that compiles a Formula 1 race into a shareable 3D browser replay — real engine sound, team radio, and the race story found automatically. Cut false overtake detections at the 2025 Monaco GP from 72 down to 12.
false passes 72 → 12
Split shared expenses in three taps. No account, no server, works offline. Integer-only money logic, balances simplified into the shortest list of who pays whom, and sharing through a read-only link with the group packed inside it.
offline-first
A free, self-hostable multiplayer drawing-and-guessing party game: an authoritative real-time game server with per-player information hiding, a drawing protocol that stays in sync, and three game modes. One Node process and a static bundle.
3 game modes
A premium digital agency platform — marketing site plus a full admin panel, with dual light/dark theming throughout and a typed Prisma data layer behind a NestJS API.
full admin panel
A browser puzzle game: 50 hand-built levels, instruction-driven gameplay, a timer system, scoring and level progression — all client-side, no backend.
50 levels
Four colours, sixteen ghoda, one argument. Classic ludo in the browser with computer opponents that actually hunt you — they count the squares behind them before stepping into your range. Pure SVG board, no assets to download.
scoring AI
Snakes and ladders the way it is actually played, with hand-drawn SVG snakes and a 3D dice that rolls instead of flashing a number.
A desi Ahmedabad property board game — buy, trade and bankrupt your friends across the city. Frontend only.
A business site for an investment firm: 10+ content sections, tuned for load performance and cross-browser support.
The site you are on. A single-page portfolio built as a Formula 1 pit wall — a hand-built Three.js car you can drag to rotate, live telemetry panels, and server-side rendering so it still loads without WebGL.

Where the data structures and algorithms practice lives — the fundamentals, kept sharp.

Happy to talk about full-stack architecture, event-driven backends, cross-platform apps, or putting LLM agents somewhere they actually earn their keep.
