About Me

Hello! I'm a software engineer specializing in infrastructure as code, distributed systems, reliability, and secure identity. My work spans large-scale platform engineering at Microsoft and founding-CTO roles building products from the ground up.

Currently, I'm a Software Engineer II at Microsoft, where I'm the lead engineer for Microsoft Graph Bicep — taking it to public preview, tripling supported resource types, and growing usage 40%. I also drive identity and security work across MSAL, Azure Identity, Entra, and M365. Outside Microsoft, I'm founding CTO of Open Health Initiative and co-founder/CTO of Mingla.

I hold graduate degrees in Advanced Computing and Electrical & Computer Engineering from Morgan State University.

Here are a few technologies I've been working with recently:

• C#
• TypeScript
• PowerShell
• Bicep
• Azure
• React Native
• Next.js
• KQL

Experience

1. March 2026 - Present

   Chief Technology Officer at Open Health Initiative

   Nigeria

   • Own architecture, engineering, security, and compliance for a healthcare payments and data infrastructure company serving Nigerian hospitals, HMOs, and government agencies
   • Designed a payments model in which card, bank transfer, WhatsApp, POS, installment, and HMO payments all reconcile into one healthcare record with a single audit trail, including offline POS reconciliation for clinics with intermittent connectivity
   • Built FHIR/HL7-based data interoperability and operational analytics; the platform is live at 6 public healthcare facilities, with 33 signed and an HMO partnership
   • Set the multi-year technical roadmap across identity, logistics, clinical AI, and a healthcare compute platform

2. September 2025 - Present

   Co-founder & Chief Technology Officer at Mingla

   Remote

   • Co-founded and lead all engineering for a two-sided experience marketplace: the Mingla consumer app and the Mingla Host app for venues and organizers, both live on the App Store and Google Play since the spring 2026 launch, with users in Nigeria, Europe, and the US
   • Architected a monorepo spanning two React Native (Expo) apps, a React admin dashboard, a Next.js marketing site, and a Supabase backend; built organizer commerce with Stripe Connect payments, orders, QR check-in, and guest lists
   • Built the growth and marketing stack — ad attribution across Meta, TikTok, Reddit, and Snap, AppsFlyer smart links, search-indexing lifecycle, transactional email, and outbound calling — plus an admin dashboard and venue-prospecting pipeline for supply acquisition
   • Set engineering governance for a team working alongside AI coding agents: a 14-rule architecture constitution, architecture decision records, CI-gated tests, and guards that block destructive agent commands

3. June 2021 - Present

   Software Engineer II at Microsoft

   Redmond, WA

   • Lead engineer and subject-matter expert for Microsoft Graph Bicep (Microsoft Graph’s Azure Resource Manager integration). Took it to public preview in September 2025, about a month after taking it on, then tripled supported resource types and grew usage 40% with full API compatibility; guide a team of two engineers
   • Set the platform’s technical direction — typed relationship modeling, singleton and stream properties, polymorphic resources, automatic type injection, and Agent Identity Blueprint support — and replaced code-change-per-resource onboarding with a configuration-driven model and end-to-end CI/CD, cutting partner onboarding from 3 weeks to 1 week and onboarding 6+ partner teams; added Copilot coding agents that automate schema generation, code, docs, validation, and pull requests
   • Separated Graph Bicep into an independent, self-hosted platform with its own repository, pipelines, and publishing workflows, speeding builds and releases and removing cross-team blockers; led its threat modeling and security-architecture review
   • Led a redesign of GraphLogs, Microsoft’s company-wide internal tool for debugging Graph requests: incident-system deep links, HTTP/TLS diagnostics, throttling fixes, sovereign-cloud support, ~20% faster query and results load time, and routing that separates customer-reported incidents from other requests — then handed it off in a stable state
   • Recurring on-call engineer for Microsoft Graph and DRI for Graph Bicep; built observability for self-hosted Graph services and Synapse-based usage and lifecycle analytics for Graph extensibility teams
   • Drove Access Token Proof-of-Possession and Web Account Manager (WAM) integration for the Microsoft Graph PowerShell SDK (220M+ downloads), aligning MSAL, Azure Identity, Entra, and M365 teams to close a token-replay attack vector
   • Led migration of the AzureAD, AzureADPreview, and MSOnline PowerShell modules from ADAL to MSAL, moving every customer off ADAL before its full retirement with zero escalations; built compatibility tooling that kept legacy scripts running through the transition

4. May 2020 - May 2021

   DevOps Engineer at Data Engineering and Predictive Analytics Laboratory

   Baltimore, MD

   • Cut data-segmentation processing time by 50% by developing a Python application that automated segmentation of API-sourced data in preparation for machine-learning models
   • Achieved 95% uptime for a cloud database by maintaining a CI/CD pipeline that autonomously consolidated social-media data on a daily basis
   • Disambiguated user identities and demonstrated a network graph of relationships between users with 90% accuracy

5. Feb 2018 - Dec 2020

   Research Assistant at Morgan State University · Johns Hopkins · U.S. Army DEVCOM

   Baltimore, MD

   • Co-authored a research paper on experimental evaluation of armor materials for the U.S. Army and presented findings to key Army stakeholders
   • Designed software in MATLAB and CAD to analyze and assess the performance of tested materials against predefined criteria
   • Developed a cross-platform mobile application backed by a MATLAB algorithm, expanding the analysis tool's functionality by 60%
