Senior Full-Stack Engineer · React/TypeScript · Bitcoin
I’ve been building web applications with React and TypeScript since 2015. For the past two years I’ve focused on Bitcoin and DeFi.
What I’ve done
- Lead Frontend Architect at CSWAP, a Cardano DEX and Bitcoin staking platform, since February 2025 (promoted from Senior React Developer).
- Built the frontend for BTC Karma, a non-custodial Bitcoin staking platform: dashboard, wallet integration, and connecting the UI to Bitcoin and Cardano smart contracts.
- Debug smart contract integrations across both the Bitcoin and Cardano ecosystems.
- Design in Figma and own UI/UX decisions alongside development.
- 2 years of production data pipeline work with Azure, Databricks, and DBT.
- Currently learning Rust by building a Bitcoin timelock vault CLI.
What I’m looking for
Remote, full-time or contract roles at Bitcoin companies, especially wallets, staking, self-custody, and Lightning. I’m interested in frontend or full-stack positions where I can own the user-facing side of Bitcoin products.
Based in the Philippines (UTC+8). Comfortable with async teams and overlapping with APAC, EU, and US hours.

Experience
Lead Frontend Architect
CSWAP 2025 - 2026
- Led frontend architecture for two production DeFi products: CSWAP, a Cardano decentralized exchange, and BTC Karma, a non-custodial Bitcoin staking platform (promoted from Senior React Developer). - Built and maintained a shared React/Next.js/TypeScript component system and frontend standards used across both products. - Built trading interfaces including candlestick and line price charts, and the BTC Karma staking dashboard (positions, rewards, wallet snapshot). - Integrated Bitcoin and Cardano wallets, including Ledger and Keystone hardware wallets, with PSBT-based transaction flows. - Diagnosed a production issue blocking Ledger users from unstaking and led the fix toward miniscript-based wallet policies. - Rewrote Cardano batch reward-withdrawal logic (Lucid Evolution, PlutusV3) to report failed and skipped positions instead of failing silently. - Turned Figma designs into responsive, performant UIs and worked closely with the CTO and founders on product direction.
