I build production backends and integrations—REST APIs, payment flows, and device bridges—that keep revenue systems running, not throwaway demos. 6+ years across senior Java roles and Android/integration delivery, plus a 5.0-rated Upwork delivery on a Jakarta EE API project. I’ve shipped high-volume Java services, Laravel + Vue products, and POS/payment work (Moneris, Clover, Pax, Verifone) with local HTTP APIs on Android (Ktor) so terminals, printers, and web POS stay aligned. You hire me when you need: A Spring Boot or Laravel API designed for real traffic (auth, validation, clear errors) Third-party integrations that don’t fail silently (payments, webhooks, Exchange/EWS, hardware SDKs) Production fixes—slow endpoints, broken deploys, “works in dev” payment bugs Optional: AI/automation wired through your API (one workflow at a time, with fallbacks) How I work: Direct updates, realistic estimates, documented handoff (OpenAPI/Postman, Docker notes, staging checklist). Available 30+ hrs/week, open to contract-to-hire. Stack: Java · Spring Boot · Laravel · Vue.js · Kotlin/Android · AWS · Docker · Kubernetes · MySQL · REST · Kafka (where needed) Based in Canada (EST) · English (native). GitHub since 2017. Send your API spec, repo, or integration error logs—I’ll reply with approach, risks, and a phased estimate.
