At Altaspec, I built a 43-endpoint FastAPI backend for a state government ID issuance platform, with a nine-state workflow across 13 roles. I implemented payment confirmation safeguards so concurrent Paystack confirmations apply only once.
At Stagepanda, I authored API contracts for the automation platform and built workflow validation that blocks invalid publishes. I also built payment-return handling for Stripe and Flutterwave and cross-timezone booking availability.
I built Aloe World, a commerce platform, as its sole author. Its 36-model API includes Redis caching and Paystack checkout with verified webhooks and idempotent payment state; I also reduced storefront payloads by about 90%.
