I build agent-native systems, production-ready APIs, and distributed infrastructure. Currently shipping autonomous QA agents at VettedAI using Gemini, NVIDIA NIM, and Playwright. If it runs in prod, it's my responsibility.
// about
The engineer who owns the outcome.
I'm an AI and backend engineer who builds agent-native systems, production-ready APIs, and distributed infrastructure using Node.js, TypeScript, and Python. Currently building autonomous QA agents at VettedAI using Playwright, Gemini multimodal, and NVIDIA NIM.
My work spans semantic search platforms with multilingual voice input, multi-stage reconciliation pipelines, logistics APIs with real-time WebSocket tracking, and Kubernetes platforms running 8+ microservices. I hold the Azure AI Engineer Associate (2026) and apply that knowledge in real systems, not just exams.
Before software, I spent two years at Sterling Bank processing 100+ daily transactions, which gave me something no bootcamp teaches: obsession with data integrity and zero tolerance for system failure.

AI Engineer
VettedAI (VFAxAPP) · Remote
- →Built autonomous QA agent system using Playwright, Gemini multimodal, and NVIDIA NIM to run end-to-end UI tests on any web product without manual scripting.
- →Engineered dual-pipeline architecture: a code-generation QA pipeline that writes and runs tests from product specs, and a UI/UX agent pipeline that evaluates visual and interaction quality.
- →Implemented 6 named browser sessions with a golden replay harness for regression detection by replaying recorded baselines against live builds.
- →Deployed event-driven testing via Render webhooks and GitHub Actions, triggering the QA agent on every pull request and surfacing failures as structured AI-generated reports.
Software Developer
- →Engineered the Recon Engine — a Python and Pandas multi-stage reconciliation pipeline (Load, Validate, Netting, Matching, Review, Write) with a distributable desktop GUI for internal finance teams.
- →Developed Greenwich.Meetings in .NET Blazor Server with clean architecture, outbox-pattern event notifications, and EPPlus-powered Excel report generation.
- →Built GRDS E-Learn, an ASP.NET Core MVC platform with SQL Server for tracking module completions, audit logging, and cookie-based authentication.
- →Engineered the Demat Memo System as a three-layer solution (WPF desktop, REST API, web portal tracker) integrating NGX/NASD market data APIs and a 60-minute in-memory price cache via ADO.NET and Dapper.
Backend Engineer
ArchSaint Nexus · Remote
- →Built production-ready logistics API with shipment lifecycle management, real-time tracking via WebSocket, and event-driven architecture using Node EventEmitter.
- →Implemented JWT authentication, role-based access control (customer, business, admin, driver), and OTP verification backed by Redis.
- →Designed async email queue with BullMQ and a dedicated worker process, decoupling notifications from the main request flow to improve API resilience.
- →TypeScript strict mode throughout; Jest + MongoDB Memory Server for business logic; GitHub Actions for CI/CD.
Channel Associate
Sterling Bank · Lagos, Nigeria
- →Processed 100+ daily transactions in core banking systems, developing a strong grounding in data integrity, auditability, and financial business logic.
- →Liaised with IT and backend engineering teams to diagnose system issues, gaining direct exposure to production incident workflows and backend system behaviour under load.
