At Qwikwire Billing Systems Inc., I owned the integration and operational data layer of a regulated payments platform, covering payment gateway webhooks, accounting system calls, and the PostgreSQL model behind transactions, invoices, and merchant records. I also built Redis-backed retry handling for failed enrolment payments.
I drove the design of multi-merchant transactions and multi-party settlement on the Access API. I resolved four slow production queries through indexing and query restructuring, cutting response times by an average of 40%.
At Qwikwire, I designed and built 30+ REST API endpoints across backend services in Python and Go, and shipped a customer-facing dashboard for 100+ merchants. I led an eleven-person engineering team and mentored three junior developers.
At DXC Technology, I built and migrated 200+ ETL jobs into Microsoft Azure Delta Lake, then ran 60 ETL jobs and converted five legacy UNIX shell scripts into Python on Databricks. I also architected a reusable, white-labelled airline dashboard and am certified in Azure Fundamentals (AZ-900).
