Professional Experience
Ignite / AtomOne / All in Bits
Senior Blockchain Engineer, Go
- Maintained and extended Ignite CLI, an all-in-one platform for building, launching, and maintaining Cosmos SDK blockchains; contributed 300+ public merged PRs across protoanalysis, AST-driven code generation, scaffold migrations, CLI UX, and developer ergonomics.
- Shipped protocol and module work for AtomOne / Cosmos SDK fork efforts, including distribution-module implementation, ADR-004 Nakamoto Bonus mechanics, governance-migration fixes, and validator-commission update logic.
- Implemented and reviewed code around IBC, validator infrastructure, consumer-chain lifecycle handling, misbehaviour validation, parameter cleanup, and Validator-as-a-Service workflows.
- Contributed to Gno / allinbits/gno-realms with IBC core and transfer realm functionality, including MsgCall helpers for IBC voucher tokens and restrictions on relayed IBC operations.
- Contributed upstream fixes and helpers to Cosmos SDK and IBC-Go, including gogoproto registry resolver handling and capability-keeper helper functionality.
- Improved developer experience through CLI scaffolding, protobuf analysis, nested RPC message resolution, custom typed arrays, daemon-mode behavior, and CI / Sentry noise reduction; integrated Claude Code and Codex into review and refactor loops as a productivity multiplier across Go and Cosmos SDK codebases.
Interchain / Cosmos Hub
Blockchain Engineer, Go
- Contributed Go code and supporting tooling for Cosmos Hub / ATOM chain development alongside the Interchain core ecosystem.
- Built module-composition and IBC-related functionality for downstream Cosmos SDK chains, including capability-keeper improvements in IBC-Go.
Polygon Hermez
Blockchain / Layer-2 Engineer, Go
- Built backend and protocol-adjacent Go services for Hermez, an Ethereum Layer-2 system based on zk-SNARKs.
- Integrated Go services with Ethereum tooling and the prover / coordinator pipeline used by the rollup operator stack.
Energi
Backend Engineer / Architecture
- Built Go backend services for the Energi DeFi stack and custodial wallet systems handling private-key custody flows.
- Owned Kubernetes deployment architecture using Helm and GitHub Actions CI/CD for blockchain services and chain-node operations.
- Implemented observability with Prometheus and Grafana for service and node monitoring across production environments.
Trust Wallet / Binance
Backend Lead, Go
- Led backend work on Trust Wallet's multi-chain indexing and integration platform, blockatlas, with 200+ public merged PRs across chain integrations, indexers, market-data routes, and full-node tooling.
- Migrated legacy Node.js services to Go, standardizing worker pools, fan-out processing, context cancellation, and production-grade concurrency patterns.
- Operated and monitored production full nodes across multiple chains, supporting wallet backend infrastructure used by a large-scale crypto wallet user base.
- Built and maintained blockchain data routes, asset metadata flows, transaction parsing, validator logic, RPC batching, and chain-specific integration logic.
Mercado Bitcoin
Tech Lead — Backend & Mobile
- Built Go and Python services for multi-chain transaction tracking and payload signing at one of LATAM's largest crypto exchanges.
- Maintained hot / warm / cold wallet scripts and key-management procedures integrated with exchange ledger and matching systems.
- Led backend, mobile, and web product engineering for customer-facing exchange workflows across iOS, Android, and web.
