Selected projects & impact
Unified Checkout Platform
Architected an event-driven checkout platform supporting any reference (cart, order, or point node), with plug-and-play payment, billing & shipping components, plus split and on-demand capture.
PCI-DSS Compliance & Payments Expansion
Led a global PCI-DSS transformation and expanded payment capabilities — Adyen, Braintree, PayPal, wallets, direct debit & Pay by Invoice — into 8-10 new markets.
8-10 new markets
Credit Risk & Fraud Automation
Built a fraud validation framework combining credit risk platforms with self-built logic across pre- and post-order journeys, plus self-serve microsites and agentic telephony channels.
~40% faster review, ~15% less fraud loss
CI/CD & Observability Overhaul
Redesigned org-wide CI/CD flow with parallelized build pipelines, automated quality gates (Sonar, Snyk, Orca), and a full observability stack (Sentry, New Relic, CloudWatch).
60% faster builds, 35% fewer incidents
Micro-Frontend Platform Migration
Modernized legacy checkout and payment applications into Node.js microservices on AWS and transformed the UI into an independently-owned micro-frontend platform.
32% scalability gain, 30% lower latency
GraphQL / Apollo API Modernization
Upgraded Fictiv's vendor/quote platform REST APIs to the Apollo GraphQL framework, and built reusable frontend components across the platform.
30% faster response, 15% better on-time delivery
