Work

India is installing chargers faster than anyone is testing them. Guidelines mandate the OCPP protocol, but no Indian body verifies that a given charger actually implements it — so units are certified on paper and still fail real cars on real highways. ChargeMark is self-serve conformance testing delivered as software: connect a charge point, run a versioned test set, get a percentage-scored report and a numbered, firmware-bound certificate that anyone can verify against a public, append-only transparency ledger.

A charging network is only as good as the software behind it. The charger is hardware; sessions, tariffs, billing, roaming and uptime all live in the management system. Electra is a charge-point management system built API-first — a multi-version OCPP gateway on the charger side, OCPI roaming on the network side, and a deterministic billing engine at the core — designed for tens of thousands of concurrent chargers. It is the natural sibling of ChargeMark: one tests the ecosystem, the other runs it.

Hundreds of millions of Indians work in the informal and contract economy with almost no infrastructure of trust behind them: no verifiable record of attendance, of wages paid, or of statutory compliance. Shramik Setu is a system of record for that work — attendance captured offline and reconciled centrally, wages and compliance held in a tamper-evident ledger, with source and destination states as first-class roles so a migrant worker's record travels with them. A setu is a bridge, and that is the point.

I spent three days in hospital in August 2026 with chest pain. I had had surgery at the same hospital months earlier, and they still could not retrieve my blood group. That is an inconvenience for a conscious patient and a danger for an unconscious one — and India's national health-data stack has no emergency path at all: every retrieval route ends at the patient tapping approve on their own phone. Samputa is lifelong consented health records built around exactly that gap, tamper-evident, releasable under the medical-emergency basis the law already provides, and designed for how Indian hospitals actually work.

Private, invite-only, end-to-end-encrypted messaging, voice and video for people with a real reason to worry about targeted surveillance — built on the Signal protocol over our own server, with a device-hardening and periodic forensic programme around it. Two design decisions define it: we hold no keys, so there is nothing to surrender that we do not have; and no alert ever wipes a device automatically, because destroying the evidence of an attack destroys the most valuable thing the service produces.

A strictly 18+ social and dating product for Indian campuses, built around compatibility games and shared activities rather than endless swiping, with sexual-health and mental-health sections staffed properly. Most of the engineering went somewhere unglamorous: verified age rails per market, a hash-chained and encrypted message store that stays admissible as evidence, and a moderation and grievance pipeline that meets the deadlines Indian and European law actually set.

Point your camera at a plate and get a calorie estimate. No account, no identifiers, nothing to correlate: the photograph is analysed in memory and never written anywhere, and the estimate lives only on your phone. The discipline about what the system deliberately never sees and never keeps is the actual product.

Every business above a certain size has the same broken front door — a number that rings into hold music, or nothing at all. And every caller wants the same modest thing: to be answered promptly, in their own language, by something that resolves the problem. I am building voice agents that handle inbound customer calls, hand over to a human exactly when they should, and are measured against the only metric that matters: did the caller get what they called for.

Crowdfunding for big-ticket projects — films first, startups after. The interesting problem is not the front end; it is that the platform must never hold the money, every promise must be enforceable, and backers deserve to verify rather than trust. So the escrow itself enforces multi-signature releases and refunds only to the people who paid in, reconciliation halts disbursement on any break, and every receipt is independently verifiable against a published, tamper-evident log.

What began as pressing buy and sell buttons became a question: could I remove myself entirely? The answer, some years and many hard lessons later, is a set of trading systems that run unattended end to end — research, signal, execution, risk, recovery and reporting. It trades my own capital and nobody else's. This is a laboratory for the questions I write about — statistical rigour against overfitting, how much a system should adapt itself, what "reliable" means when no human is watching — not a service, a fund, or an offering of any kind.
