Building the crypto banking layer the world actually needs
Eight years across every stack in fintech and crypto: wallet recovery, L2s, treasuries, crypto back offices, and retail apps that have processed over $2B. Founded Open Wallet — one platform for crypto, fiat, cards, and payments, used by 56,000 people. Self-custodial. No seed phrases. Consumer UX down to protocol.
Experience
Open Wallet
- Shipped one app for crypto, fiat, cards, and payments — so sending $20 does not mean five apps, 2–5 day wires, and a lost seed phrase. Multi-chain wallet, instant swaps, Bitcoin L2, payment cards, and a bank-like account without bank limitations. 56,000+ users.
- Keyless recovery: MPC, passkeys, and an encrypted recovery key (client-side; neither Open Wallet nor the encryption vendor can spend funds). Restore from any device with an OTP — full access in under 60 seconds. Helped recover wallets for 7,000 customers amounting to over $5 million. No seed phrases.
- Personal EUR/GBP/NGN named bank account: wire from any bank, receive USDC/USDT in self-custody. Freelancers get paid by clients who never touch crypto. Direct-to-Bank the other way across 16 corridors (INR, PKR, VND, NGN, KES, GHS, ARS, BRL, MXN, COP, PHP, IDR, TRY, EUR, GBP, CNY) — including 200+ Indian banks and 114 Vietnamese banks.
- Cross-chain by default (Bitcoin, EVM, Solana, TON, TRON, Litecoin), one-click dApps, DeFi. Wrote the first lines of code, then ran product and engineering across a small team in Estonia, India, and Romania.
- HodlFlow was the product thesis: earn on idle stables, borrow against BTC/ETH without selling, move to a bank — hold, earn, borrow, move, repeat — in self-custody.
- A customer who had lived outside India for 11 years put €20,000 down on property with no bank loan and no BTC sold: EUR in via personal IBAN → USDC on Ethereum → WBTC on the in-app DEX/CEX → Morpho borrow at 75% LTV via WalletConnect → INR via Direct to Bank in 90 seconds. European bank saw a wire; Indian bank received clean INR. Write-up.
Yolo Group
- Built Bombay Wallet for HNIs and family offices — spend fiat and crypto across land-based casinos, plus concierge ordering in-app. Processed over $800M with 400 customers. Product of the Year, Yolo Awards 2023.
- Integrated Luxon, open banking, and several on-ramp providers to pull money straight from a bank or card and convert it to stablecoins in one flow. Unique EUR IBAN per verified user (receive + SEPA send), custodial BTC/ETH/USDT wallets, Lightning via Lightning Labs, AMLD5 KYC through SumSub / Onfido.
- Helped ship the Sportsbet.io consumer app — a crypto sportsbook and casino for high-volume retail — and Hub88, the operator back office (real-time GGR, turnover, invoices).
- Built iStream, the first Bitcoin Lightning wallet we shipped — App Store approved and used by 2,500+ customers in public beta. We chose not to take it fully public: the Lightning UX was too complex for a mainstream audience at the time.
- Built pay.io to accept and track Bitcoin at land-based casinos and poker clubs — on-chain or Lightning, a quarter euro to €250k in under a second, with invoicing and bookkeeping.

Case studies
Morpho Midnight applied in two directions: idle FX float that can still earn (Ladder), and float that still has to fund every payout (Meridian).
