Kids video platform with curated stories, parental controls, and subscriptions. Multi-tier user system (9 tiers), Razorpay/LemonSqueezy payments, push notifications, and AI-generated content.

Vedic astrology matching platform — 6 match types with 4-level scoring (Guna + House + Dasha + Navamsa), AI chat, Muhurta finder, face reading, and palmistry.

Recipe manager with Ayurvedic health scoring — 8-factor compatibility analysis based on Charaka Samhita. Personalized recommendations using dosha, ritu, and agni.

Ayurvedic daily routine tracker with Dosha Kala time blocks, personalized guidance based on prakruti/vikriti/ritu, and AI coaching with 10 specialized tools.

Business intelligence from app store reviews — bulk scrape from App Store & Play Store, sentiment analysis, resumable pagination, and styled Excel export with color-coded scores.

Ayurvedic pregnancy guide (Garbhasanskar) app — daily activities, month-specific yoga videos, diet plans, raga-based music for fetal development, and expert-guided fetal communication audios. 4.9 rating, 3K+ downloads. Built from scratch as Co-founder & CTO at Prachet Lifetech (2020–2026).

Firestore-only shopping app with Razorpay one-time orders. HMAC signature verification, atomic stock decrement in Firestore transactions, and review gating that only lets verified buyers post. Server Components for public catalog, client pages for cart and checkout.

Daily planning ritual: log what shipped, plan the next two days, invite mentors to comment, and ask AI to synthesize next priorities. Owner/advisor access model via Firestore rules, plus an admin-only AI mentor with 5 tools (recent entries, pending plans, advisor comments) built on @repo/chat.

AI meeting recorder. Captures both microphone and system audio (Zoom/Meet participants) via Web Audio API into one MediaRecorder stream, transcribes with Deepgram Nova-2 speaker diarization, then generates a structured summary via Claude. Audio archived to Firebase Storage, metadata in Firestore.

Personal project/task tracker. Firestore-only with single-user data namespacing. Projects + nested tasks (subtasks via self-referencing parentTaskId), status and priority workflows, URL-safe nanoid IDs. Built to replace context-switching into Linear for solo work.

Toggl-style time tracker. One-click start/stop timer with a persistent bar, projects with hourly rates and color, clients, tags, and reports — time-by-day bar chart, project pie chart, CSV export, date range filters. Pricing page for 4 tiers already scaffolded.

Your browser's new homepage. Save any URL, press ⌘K, get fuzzy search across title, URL, domain, notes, and tags — ranked by click count plus a 7-day log-decay recency score. Paste-to-save, tag-grouped hub, optimistic mutations with rollback, Google favicon CDN. Multi-tenant from day one.

tldraw-powered infinite-canvas whiteboard. Each Firebase UID gets its own IndexedDB store, so state, undo/redo, and cross-tab sync come free — zero backend code. Phase-2 roadmap swaps persistence for a Firestore-backed TLStore for cross-device sync and multi-board support.

Zoom-like video meetings. Agora RTC for video/audio/screen-share, Agora RTM for signaling (reactions, raise hand, host broadcasts), server-signed tokens, Firestore for meeting and participant metadata. Multi-party gallery up to 9, waiting room, host controls (mute-all, remove, lock, transfer), in-browser recording to Firebase Storage.

Anonymous chat by shareable link. An owner signs in, generates /c/{chatId} links, and anyone with the link writes anonymously — no sign-up. Either side can escalate to a 1-on-1 Agora voice or video call. All writes go through rate-limited tRPC routes using the Admin SDK; client SDK cannot write messages.

In-browser Hare Krishna chanting tracker. Whisper (WebGPU when available, WASM fallback) transcribes rolling 5-second audio chunks entirely on-device, detects mantra boundaries, and grades each 0–100 (A/B/C/D) on five signals: clarity, completeness, rhythm, volume steadiness, and focus. Model cached in IndexedDB after first download.

Time-aware classical raga player. Every recommendation is traceable to shastra — prahar, dosha kala, ritu, and mahadasha drive the ranking; no LLM in the loop. Library ships with 17 raga docs and 32 audio tracks across bansuri, vocal, and instrumental variants. Admin-only seeding keeps the catalog curated.

On-device ergonomic posture monitor for developers. MediaPipe Pose Landmarker Full (33 landmarks with normalized Z) detects forward head, shoulder hunch, head tilt, and lateral lean. Calibrates to your own good posture in 3 seconds; alerts via browser Notifications after ~10s of poor posture. Aggregate stats only — never stores video or keypoint frames.

Romantic photo-art studio. Upload a photo, type a name, pick an effect, download the result — 9 canvas-based effects (Polaroid, Pop Art, Neon Dream, Halftone Heart, Golden Hour, Starlight, Watercolor, Graffiti, Lovestruck). 100% client-side, no uploads, no AI bill, no backend round-trip. Theme deliberately diverges from the Anthropic palette into Midnight Rose.

Template app for bootstrapping new products in the monorepo. Pre-wired with Firebase Auth (cookie sessions + RBAC), Prisma, 4 AI providers, Redis, Resend, Sentry, GA4, React Query, and shadcn/ui. Ships with a single-source-of-truth sign-in pattern forged from real production incidents.

This site. Static showcase of 21 apps in the monorepo plus resume, built as a Next.js Server Component for cacheable HTML and zero client JS on first paint. Shares the same Firebase Auth, Prisma, Sentry, and GA4 stack as the other apps — same seed, different surface.
