Professional Experience

50K+ orders/day 99.98% uptime $2M+/mo processed $1.2M/yr saved

Own end-to-end development of a multi-tenant shipping platform and led the monolith-to-microservices migration on Java/Spring. Cut average API latency from 1.2s to 450ms with Redis + async processing, re-engineered order tracking on Elasticsearch at 10K+ QPS, and integrated Moneris, Authnet, and PayPal with a 99.95% payment success rate. Right-sized AWS instances to unlock auto-scaling and drove team-wide AI dev-tool adoption for a ~25% sprint velocity lift.

6+ client projects 30% fewer defects 45% faster loads 20+ UI components

Delivered full-stack work across 6+ client projects using Java, Spring, and Angular — optimizing queries and schema to enable a tier-down on hosting without performance impact. Built a reusable UI component library that cut front-end effort 25% across subsequent projects, and deployed zero-downtime AWS infrastructure (EC2, S3, RDS) with auto-scaling groups across multiple client applications.

3 stakeholder orgs 1 working prototype

Prototyped a technically viable solution addressing TELUS's core business requirements, applying software design, database management, and OOP coursework. Coordinated across Lambton, TELUS, and the internal team to run kick-offs, track progress, and deliver the final prototype demo with technical documentation and tradeoff summaries.

100K+ end users 200+ tests written 150+ issues resolved 40% QA effort cut

Built and maintained Java/Spring backend modules for e-commerce applications, writing JUnit and integration suites that shortened release cycles by a full week per sprint. Ran root-cause analysis on production issues via JIRA, automated historical billing backfills to eliminate migration work on new projects, and authored API references for 10+ backend modules to speed developer handoff.

4 mainframe techs

Completed specialized training in Mainframes — COBOL, JCL, CICS, DB2 — then performed enhancements and internal support on legacy tooling. Contributed to work-product reviews and brainstorming sessions focused on reducing delivery defects.
