About

•Frontend-leaning full stack engineer, 2 years in. Build production web and mobile products: Angular and React at enterprise scale, plus the services behind them when a product needs both.

•Built the housekeeping app a hotel chain runs daily across its properties, Taj Dubai and Emirates Palace among them. It is a multi-org Progressive Web App with a custom service worker for offline use and deep-linked push notifications, and Web Workers that keep heavy parsing off the main thread. Proposed the 12-library V2 rewrite and led it, shipped in 1 month. Delivered the NHRI Dubai government website alone in 7 days, shipped a multi-role SaaS as the only developer, and won $1000 at a hackathon.

•Day to day: TypeScript, React, Next.js, Angular, SignalStore, Tailwind CSS, Framer Motion, Service Workers, Web Workers, Progressive Web Apps. Behind the interface: Node.js, Rust, Kafka, PostgreSQL and Kubernetes. Care how a product feels to use, and like owning one all the way through.

Currently available for remote frontend roles. Based in India (IST / UTC+5:30). Can overlap with US or EU hours. Reach out at vaibhavzope18@gmail.com

OpenBot is an open-source product with 4.9k stars, where every AI coworker gets its own computer. Landed 35+ pull requests upstream, and rebuilt the interface alongside that. The revamp only runs locally, so a walkthrough is how you see it.

Shipped

Merged upstream35+ pull requests merged into the main repository, across product, correctness, browser, state, storage, networking, tooling, reliability and safety. They name a conversation and draw it where the last message was, follow a popup sign-in window so a person can finish signing in, anchor the transcript on the first token, and tell a channel that was running that it stopped.
Interface revampRebuilt the product's interface locally: 45+ components over 7 surfaces, covering channels, agents, routines, skills, admin, settings and new chat. It has a resizable sidebar, a composer shared across entry points, generated coworker avatars and a flat dark palette.
Review and triageRead other contributors' pull requests and the issue backlog, then picked work maintainers care about instead of whatever patches fastest.

Built a live wellness platform from a client-supplied design, as the only developer. It has customer, mentor and admin interfaces, calendar booking against real mentor availability, auto-provisioned Zoom sessions and Razorpay checkout.

Shipped

Design to productionTurned the client's design into a responsive Next.js interface for 3 roles: customer, mentor and admin. The booking flow reads live mentor availability and holds a slot until payment finishes.
Companion mobile appShipped a React Native (Expo) companion app sharing the same booking flow, so a session can be booked and joined from a phone.
Admin CMSBuilt an admin content interface covering 4 content types over 14+ Prisma entities on Neon PostgreSQL behind NextAuth v5, so the client edits the site without a developer.

Owned the frontend across enterprise hospitality products: a government website delivered alone in 7 days, a multi-org Progressive Web App running daily for a hotel chain across Taj Dubai and Emirates Palace, and a 12-library rewrite of the client layer.

Shipped

NHRI Dubai public websiteDelivered the National Human Rights Institute of Dubai's public website alone in 7 days. It is an Angular front end with GSAP scroll and reveal motion, fully bilingual across right-to-left and left-to-right layouts. The Umbraco back office lets the institute's own team manage content, media and the enquiry records that reach their CRM. They kept me on as product owner after launch.
Housekeeping Progressive Web AppBuilt a multi-org, multi-property Progressive Web App across 5 modules for a hotel chain, used daily by housekeeping teams across its properties including Taj Dubai and Emirates Palace. A custom Firebase service worker delivers deep-linked push notifications that open the exact room task, and caches the shell so a housekeeper on weak in-building Wi-Fi keeps working; heavy task and roster processing runs in Web Workers so the list never blocks the main thread, and gRPC-web binary transport keeps payloads small on hotel networks.
V2 architectural rewriteProposed a complete V2 rewrite of the client layer and led it: an Nx monorepo of 12 shared libraries on SignalStore, shipped in 1 month. It retired a year-old bottleneck, and new developers could then onboard without causing regressions.
Grevon AI embeddable widgetBuilt a framework-agnostic embeddable trip-planning chat widget in Stencil.js. Shadow DOM isolation keeps it rendering the same on any host site. It carries a custom gRPC-web client, real-time Firebase chat, Mapbox rendering and Stripe payments.
Booking AppRescued a stalled 3-platform room-booking product (Ionic mobile, web, tablet) with no architecture or CI/CD; established the structure and Firebase SSO, and configured GitLab CI/CD with multi-stage Docker builds and Kubernetes deploys with rollback tagging.

Lovable for Anchor smart contracts. Hackathon winner

An AI platform that cuts Solana smart contract development time by 80%. You write a prompt in plain language and get a deployed Anchor contract in under 5 minutes. It runs a multi-stage LLM pipeline, shows the reasoning live, and compiles inside isolated Kubernetes environments. It processed 1000+ contract requests during testing.

Built

•Shipped 6+ AI-assisted features: contract generation, code analysis, security suggestions, and IDL and client SDK generation.
•Built end-to-end platform: Next.js 15 frontend with Monaco Editor (Rust syntax highlighting), LangChain multi-stage LLM pipeline (planner → coder → finalizer), and real-time streaming via SSE.
•Built a containerized Anchor build, deploy and test environment on Docker and Kubernetes. Each compile runs in its own container, so one person's broken code can't affect anyone else's.

Challenging (but overcame)

•Designed a 4-service system with one-click deployment and live monitoring. It scales to 100+ concurrent compilation jobs on Kubernetes with a BullMQ queue. Concurrency limits, job timeouts and graceful failure keep it responsive under parallel load.
•Won $1000 USD at a competitive hackathon against teams with larger engineering groups.

Orderbook

full-stack application

github.com/zopeVaibhav/orderbook

A trading platform: live order book, matching and settlement

A trading platform where you place an order, watch it rest on a live book, and see it fill. A price-time priority matching engine runs behind a Next.js trading client, split into 3 services over Kafka: matching, API and settlement. It handles limit and market orders, partial fills, indexed cancellation, and double-entry settlement with exact decimal precision.

Built

•Decoupled the system into 3 services over Kafka, with bincode snapshot persistence so the in-memory book recovers after restart.
•Shipped a Next.js client with JWT and Google OAuth on top of the API service, in a Turborepo monorepo.

Challenging (but overcame)

•Built the matching engine with price-time priority, using BTreeMap price levels over FIFO queues. It supports limit and market orders, partial fills, and indexed order cancellation.
•Wrote a double-entry settlement service posting balanced ledger entries per trade with idempotent trade references and exact decimal precision, so no trade can be applied twice or drift on rounding.

AI workspace assistant: a stateful LangGraph agent over Gmail, Drive and GitHub

A workspace assistant built on a stateful LangGraph agent over Gemini. It plans a request, calls tools in a loop across your connected workspace accounts, and self-reviews its answer with a critic node before returning it.

Built

•Shipped as a Bun and Turborepo monorepo: a Next.js 16 chat client, an Express 5 API with JWT auth, and chat persistence on Prisma and PostgreSQL.
•Containerized the whole stack with Docker Compose for one-command deploys.

Challenging (but overcame)

•Built the LangGraph agent across 4 node types: router, synthesizer, tool executor and critic. The graph plans, loops through tool calls, and critiques its own output before answering.
•Integrated 3 OAuth-scoped workspace clients (Gmail, Google Drive, GitHub) so the agent searches mail, reads documents, and queries repositories on the user's behalf without over-scoping access.

Live quiz platform, co-created with a small team. I did interface and interaction work across the web app

A live quiz platform I co-created with a small team. A host runs a session, and participants and spectators join in real time. The product belongs to the team, not to me alone. My work was mostly the web app: the quiz library surfaces, the live participant screens, and the interaction hooks under them. I also fixed the token refresh path when sessions were dropping mid-quiz.

Built

•Built and restyled the quiz library surfaces: grid view, options and trash panels, recently-viewed cards, the upper section and the quiz action navbar.
•Shipped a gooey toaster, an upload-PDF control and the pricing component on the revamped marketing surface.

Challenging (but overcame)

•Wrote the interaction hooks the live quiz depends on: draggable quiz cards, key-press handling, and page-visibility tracking that warns a participant or spectator as soon as they leave a live session.
•Fixed the refresh-token path end to end (server controller and auth middleware) so a session no longer expires out from under someone mid-quiz.
