Deep Dives
The full story behind each build — the problem, the approach, and what changed.
Indian retail investors had no screener combining fundamental, technical, and risk analysis with explainable ML.
Three-service architecture — FastAPI quant, NestJS API, Next.js frontend.
Screener ranking ~200 NSE stocks with combined scores. Paper trading + portfolio. PWA installable.
Devotional art business needed to scale wholesale→D2C without losing reverence. Platforms couldn't handle 50K+ bilingual SKUs.
Bilingual Next.js storefront, Cloudinary media, Supabase/PostgreSQL catalog, custom gallery honoring artwork.
Live at enterprise scale. SBI, Bikaji, Zee News for corporate gifting. Wholesale→direct revenue.
Indian classical musicians had no digital tool understanding raag/taal/theka/rasa. Western apps force 4/4.
Custom browser DSP with Tone.js + Web Audio API. Precise tanpura synthesis, interactive taal chakra.
Daily use by musicians. Taal chakra cited in music education. 44.1kHz/48kHz with sub-millisecond jitter.
Digital sacred texts were cluttered with ads, missing texts, or generic e-readers. Practitioners needed silence.
UI stripped to nothing. Offline-first PWA. Typography tuned for Devanagari. No analytics, no tracking.
Daily use across India/diaspora. Zero bounce on text pages. Offline works in temples, flights, remote areas.
Judiciary aspirants had no tool matching actual exam conditions with new criminal laws (BNS/BNSS/BSA).
Two platforms sharing Django backend — Next.js web + React Native mobile. Ingestion scripts map 10yr PYQs.
Primary prep for aspirants. BNS/BNSS/BSA mapping live before coaching centers. DAU growing via word-of-mouth.
Engineer's portfolio was a marketing page, not proof of craft. Work deserved a system demonstrating architecture.
Turborepo monorepo. Micro-frontends. GitHub Actions CI/CD. Sentry error tracking. The portfolio is the reference impl.
Portfolio is a teaching tool. Preview deployments = every PR is live demo. Zero-downtime deploys.
