hi there, I'm
Hillori.

About me
I build for the people on the other side of the screen.
What I care about most is simple: whether what I build makes someone's day a little easier. I've built for learners, sales teams, IT teams and my own colleagues, and that question has guided all of it.
I work across the whole stack — AI, payments, mobile, growth — because users don't experience a product in layers. I'd rather own a problem end to end than hand it off halfway.
Beyond work, I'm an explorer — reading thought-provoking books, making videos for my YouTube channel, or finding new corners of the world.

where I've been
The mission, in practice.
Where that mission has turned into real products — and what changed for the people who use them.

Supernova is an AI spoken-English app — the #1 Education app on India's App Store. With a tech team of four engineers and a CTO serving 2 million learners a day, I own whole stretches of their journey.
- learners practising every day
- 2Mlearners practising every day
- payments that just went through
- 435Kpayments that just went through
- live experiments improving lessons
- 36live experiments improving lessons
- people heard out before leaving
- 15K+people heard out before leaving
A learner's journey — what I built at each step
- 1
Learn
Lessons that keep getting better
- Supernova app
Every learner moved to a new course system mid-journey — and nobody lost their place.
What I built: Architected CourseV2: the data model and progression algorithm, a staged rollout, and automatic migration of in-flight progress.
- Supernova app
Lessons improve week after week, because the content team can create, reorder and test courses on their own.
What I built: Designed CourseV2 for experimentation with no engineer in the loop — 36 live experiments across 123 variants.
- Supernova app
More real-life conversations to practise, in learners' own languages.
What I built: A GenAI scenario-generation pipeline, plus the Course and Activity translation APIs behind multi-language support.
- SuperPrep
Exam students can ask questions about their study material and get answers grounded in it.
What I built: Document-grounded Ask AI (RAG) for SuperPrep, our exam-preparation app.
- Supernova app
- 2
Speak
A tutor that's always there
- Nova AI
Learners can show their AI tutor a photo, a PDF or a file — not just type at it.
What I built: Redesigned Nova AI, the in-app tutor used by 2M people a day, with a new AI tab for image, PDF and file uploads.
- Supernova app
Conversations keep going even when a speech provider goes down.
What I built: Multi-provider text-to-speech and transcription failover with health tracking; every new provider validated with evals and manual audio review.
- Superflow
The names, companies and places each person actually says get spelled right.
What I built: A personalised transcription dictionary mined from each user's transcription logs, with the surface built in Expo UI and edit-in-preview in native Android.
- Superflow
The translation widget stopped vanishing — and now brings itself back if the phone shuts it down.
What I built: Traced a top complaint to the OS killing the background service, and restored it automatically with high-priority Firebase Cloud Messaging wake-ups.
- Nova AI

Pay
Paying that just works
- Supernova app
239K learners have paid smoothly through a gateway I integrated in my first month — 435K payments and counting.
What I built: Two-phase payment flows and idempotent webhook processing, so no payment is lost or counted twice.
- Supernova app
iPhone learners got a proper way to pay, with invoices — around 67K now learn on paid plans.
What I built: Launched iOS payments with gateway support and invoicing, where only in-app purchase existed before.
- Supernova app
Learners who were owed refunds got their money back.
What I built: Root-caused systemically missing refunds; designed the refunds and disputes model, webhooks and a historical backfill — shipped with zero follow-up fixes.
- Supernova app
Every purchase comes with a correct GST invoice.
What I built: GST-compliant invoicing across every payment path, delivered on a regulatory deadline without disrupting live checkout.
- Supernova app
- 4
Stay
Listening before someone leaves
- Supernova app
15K+ people thinking of leaving were asked why, instead of just being shown a cancel button.
What I built: A configurable cancellation and retention platform — new retention experiments ship as configuration, not code — instrumented from day one.
- Team tools
The people who look after learners — product, content and ops — get answers and tools without waiting on an engineer.
What I built: Metabase dashboards for funnel data, Retool for content operations, and Vibetool, which puts the latest translation models and prompts in the content team's hands.
- Supernova app
