La major part del que construeixo es mou entre pagaments amb stablecoins, sistemes d'agents i el tooling que hi ha a sota. Alguns projectes em van portar un cap de setmana i d'altres anys, i el codi és públic sempre que pot ser-ho. A cada visita es mostra una rotació diferent.
A gateway that routes AI calls across providers and keeps track of usage.
Problem — Routing and metering LLM calls by hand works for one project, then falls apart.
Built — A gateway built with Bun and Hono that routes, meters, and logs calls across providers, backed by Postgres.
A suite of tools for running a DAO on Aragon: projects, budgets, voting, bounties.
Problem — Aragon let you vote, but running a DAO day to day needed more than that.
Built — Founding team at Autark; shipped this suite to Ethereum mainnet, funded by three Aragon grants.
Group funds onchain: create a pool, share a QR, spend together in USDC.
Problem — Splitting and pooling money at events still runs on spreadsheets and trust.
Built — Joined very early as founding partner and tech lead; two-plus years on escrow contracts, the PWA and event deployments.
An agent OS you navigate in four dimensions, with an AI living inside it.
Problem — Running several agents at once needs a home that isn't just a chat window or a dashboard.
Built — A SolidJS shell with 4D navigation, a color system built on OKLCH, and a command palette. Phase 1 is done.
Swipe to donate crypto: the swap and the gift happen in one step.
Problem — Donating crypto usually takes several steps, and people drop off at each one.
Built — A swipe-to-donate flow where the swap and the donation settle as one transaction. Live on MiniPay and as a Farcaster Frame.
Essential-service payments in LATAM, settled in stablecoins.
Problem — Underbanked users in LATAM can't reliably pay essential services with the rails they have access to.
Built — A stablecoin-settled (USDC/cUSD) payment PWA with AI-agent-guided onboarding.
Sovereign input and clipboard continuity across hosts: a self-hosted Universal Control.
Problem — Universal Control-style continuity shouldn't require an Apple ecosystem or a cloud relay.
Built — A cross-host continuity daemon, migrating from a Python prototype to Rust (quinn QUIC, mdns-sd) with a Tauri + Svelte front end.
The first testing framework for Aleo, a zero-knowledge blockchain.
Problem — Aleo/Leo had no dedicated test framework: every ZK program was verified by hand.
Built — Co-built the framework in Rust at Istanbul DevConnect; later applied it to an Aleo Blueprint grant.
My entire homelab as declarative NixOS code. Multi-host, reproducible.
Problem — Homelab servers drift from each other and from any record of how they got that way.
Built — A multi-host NixOS flake (flake-parts, import-tree, custom modules) plus a Hyprland desktop: every host reproducible from source.
DeFi observe-decide-execute tooling: account-abstraction wallets, multi-protocol yield routing.
Hi segueixo tornant perquè construir alguna cosa en un cap de setmana amb gent que acabes de conèixer continua sent la manera més ràpida que conec d'aprendre. Al registre hi és tot, les victòries i també els projectes que es van quedar en res després del cap de setmana.
Trustless poker on Aleo using SRA encryption and zero-knowledge proofs.
Pay essential services with stablecoins from MiniPay.
Swipe-to-donate on MiniPay: the swap and the gift settle as one transaction.
Leology, a testing framework for Aleo. Built with a team of five.
M'importa el codi obert, i gairebé tot el que faig acaba sent públic. Bitcoin va ser la meva porta d'entrada, i l'enginyeria és el que m'ha mantingut aquí. Vaig fer classe en un màster de blockchain durant set anys i vaig formar part de l'equip fundador d'Autark, on construíem una suite empresarial oberta per a DAOs a la mainnet d'Ethereum. Els hackathons continuen sent part de la meva rutina (a sota hi ha el registre complet), i a casa munto la meva pròpia infraestructura, perquè m'agrada saber què estan fent els meus sistemes.
La major part del meu temps se l'emporten SwipePad i DigiPaga, dues apps de pagaments amb stablecoins que van començar com a prototips de hackathon a Celo i ara són productes en producció. La resta la dedico a sistemes d'agents, una petita flota d'assistents autoallotjats que corren al meu homelab. Aquesta part encara és verda i es trenca més del que m'agradaria.
Si tens curiositat per alguna cosa del que hi ha aquí, o vols construir alguna cosa junts, escriu-me (soc @ottodevs gairebé a tot arreu).
