Senior Frontend Engineer specializing in FinTech and distributed systems

El Salvador, El Salvador8y exp

“Senior frontend/product engineer with uncommon depth in both decentralized peer-to-peer messaging and high-frequency crypto trading interfaces. Has owned product surfaces end-to-end at Holepunch and Bitfinex, including protocol-aware architecture, cross-platform TypeScript/React systems, and measurable performance wins like 40% responsiveness improvement and 66% faster media uploads.”

“Software engineer/QA automation leader with Lowe’s experience owning automation quality strategy for a customer-facing platform supporting large contractor orders. Built TypeScript/React dashboards backed by Spring Boot microservices (MongoDB) and RabbitMQ async messaging, with strong CI/CD test automation and production monitoring (Prometheus/Grafana). Also created an internal automated test reporting dashboard that improved QA workflow through training-led adoption and iterative refinement.”

“Engineering leader focused on developer platforms and open-source frameworks/SDKs, with strong community and release-engineering chops. Drove major reliability and DX improvements (30–50% faster release cycles; 2–3x repeat contributors; ~50% faster onboarding) and led an incremental Python monolith to TypeScript event-driven migration using Protobuf contracts, feature flags, and a plugin architecture to preserve backward compatibility.”

“QA automation engineer with Silicon Valley Bank experience owning end-to-end test automation for customer onboarding and payments. Built a hybrid framework (Playwright UI, REST Assured API, Python + SQL backend validation) integrated into Azure DevOps CI/CD with PR gating and nightly regressions, catching high-risk issues like silent API contract breaks and missing payment ledger entries before release.”

“Backend engineer with banking-domain experience building production microservices and Kafka-based transaction processing systems. While they have not yet shipped a full LLM agent, they bring relevant distributed-systems expertise in reliability, observability, idempotency, and event-driven workflow design, including a reported 15-20% performance improvement.”
