I'm building API-driven backend products for fintech, transactions, webhooks, and operational reliability. My work spans Python/FastAPI and TypeScript/NestJS/Node.js, with PostgreSQL and Redis at the core.

At Product Studio HQ, I supported fintech workflows for authentication, SSO/JWT, OTP/2FA/TOTP, KYC/BVN verification, payments, and third-party integrations. I worked with TypeORM, MySQL, BullMQ queues, S3-backed file workflows, testing, debugging, and Git-based delivery.

In independent client engagements, I've delivered web development work across frontend, backend, and API-driven applications, including an InstaGrowth administrative dashboard and a shopping-cart checkout frontend. I also developed responsive interfaces at TechCertify Solutions and gained security operations experience through Splunk/SIEM alert triage and log analysis.

My recent projects include a webhook operations platform with persistent delivery state and retries, an autonomous options trading agent, a race-condition-resistant booking API, and a Redis-cached financial-data proxy. I focus on validation, concurrency control, testing, caching, rate limiting, and production-oriented debugging.
