I build the app on your phone and the server behind it.

• Turns a recorded consult into a structured clinical note in about 30 seconds. Every section shows the words in the transcript it came from.
• Client Chats: the clinic’s WhatsApp and SMS in one shared inbox, with an assistant that answers from the clinic’s own profile and hands anything about a pet’s health to the vet.
• Audited 37 screens and 198 issues, then redesigned the whole web app around a calmer, faster layout.
• A Chrome extension that pastes finished notes into ezyVet, and a practice-management system built on OpenVPM.
• Built the new website, its animated hero and both films. The motion scenes are written in HTML and CSS, then rendered to video.

Built with React, TypeScript, Node, PostgreSQL, Twilio, Google Cloud, AWS, Astro

• Built the Android and iOS app, the website, the staff console, the API and the background services: five repos, about 1,500 commits since 10 September.
• Live webinars on LiveKit with co-hosts, screen sharing from a phone, and joining from up to three devices.
• Every webinar is recorded twice, by LiveKit and by a recorder I built on AWS Fargate. Recording stops only when the last person leaves.
• Push to Android and iOS, phone sign-in, chat with voice notes and reactions, scheduled broadcasts and a forced-update gate.
• About 1,500 backend tests. One feature per release, behind a flag.

Built with Expo and React Native, NestJS with Fastify, Next.js, PostgreSQL, AWS

• WhatsApp across five providers behind one inbox, with failover, a daily limit per number and opt-out handling.
• A browser dialer and a call center for cold callers: a line per agent, recordings, transcripts and call outcomes.
• Every Facebook ad traced to the lead it brought in, across three repos, and reported back through the Conversions API.
• Video consultations on LiveKit with multi-part recording, so 100-minute sessions are kept whole. Calls become Hinglish transcripts, client dossiers and PDF reports.
• An event-driven task engine with 29 tasks, and an MCP server that lets AI agents work with the CRM.

Built with Node, TypeScript, Express, Supabase and PostgreSQL, React, LiveKit, Capacitor

• An MCP server with 34 tools. Screenshots go back to the model as images, and its taps are mapped back to the real screen.
• Safe on someone’s own phone: a guard that fails closed, and it never uninstalls an app.
• Scenarios with several actors, say a host in Chrome and a viewer on a phone, with a report and a video of every run.
• It started when an agent caught a rotation-only bug in a live-video feature that unit tests had missed. 87 tests.

npm install -g duet-qa

Built with TypeScript, Node, adb, Puppeteer, MCP

• A console and a browser page over every live session: files changed, test runs, issues, commits, tokens and subagents.
• Press r for an AI review that checks a session’s claims against what actually ran.
• Its router sends each delegated task to the cheapest model that can do it, and retries a tier up when it fails.
• No server and no open port. Two adversarial audits and 45 tests.

/plugin install agent-watch --marketplace AdityaSingh-byte/agent-watch

Built with Claude Code plugin, Node

• Reads bank and UPI messages on the phone and remembers which message every amount came from.
• Teach it one message it missed and it learns the pattern for that sender.
• Finds duplicates, transfers between your own accounts, and bills.
• Encrypted backups, and a website with no JavaScript at all.

Built with Kotlin, Jetpack Compose, SQLite

• Every level is checked by an expectimax solver before it ships.
• A headless simulator runs about 88,000 checks on the game rules.
• A closed test with 14 testers came back 100% crash-free.

Built with Java, Android, AdMob, Firebase
