Experiences

Mar 2026 – Now

Primary engineer on a bank direct-debit product: built the Go partner API client, the GraphQL enrollment lifecycle, and a scheduled collection job with regulatory hours gating and row-level locking.
Owned a regulatory compliance project end-to-end, design through production: an event-driven stamping pipeline in Go on Kafka and GCS, with retry/DLQ handling for vendor downtime and audit records in BigQuery.
On-call for payment and card systems: triaged PagerDuty escalations to root cause via Grafana and Prometheus, then shipped five remediations across payment idempotency, error typing, and vendor-state recovery.

Jun 2025 – Dec 2025

Led design reviews for the partner extranet convergence initiative, presenting API and frontend architecture proposals to 10–30 cross-functional stakeholders — directors, engineering managers, product owners, system maintainers.
Migrated 5 high-traffic extranet pages (thousands of daily users) off the legacy monolith to microservices (React, C# .NET), including property-type-driven dynamic form configuration.
Built out the testing diamond: unit tests for utilities, contract tests against third-party microservices, and end-to-end acceptance tests in production-like environments.
Folded review feedback back into the designs, including migrating to newer API endpoints surfaced by stakeholders.

Apr 2024 – Feb 2025

Architected a Bitcoin wallet auth library: one adapter pattern covering 4 providers, giving several Web3 apps a single signature-based login path.
Built a Bitcoin NFT launch platform that sold out its first round (tens of thousands of dollars), using the Mempool API for transaction management and investor verification.
Shipped core DEX features — liquidity pool management and token swapping — for a Uniswap V2/V3 fork on Mantle.
Extended a smart-money tracking platform (20K+ users) from Ethereum to Solana, adding wallet analytics and transaction history views.
