I help make complex systems easier to trust.

Andrew Bolaji smiling in a tan suit inside a greenhouse

Customer-facing engineer with nine years in production software. I turn ambiguous customer problems into verified improvements. At Vestmark, I helped reduce an hours-long financial file-delivery workflow to roughly 10 to 15 minutes. I also build and release products.

01 · Work

Selected work.

Customer delivery, released products, and technical systems, with their operating evidence and current limits stated plainly.

Custos access comparison for HR and standard users

Custos · Private AI demonstration

Access before retrieval.

A permission-scoped retrieval demonstration. A document outside the selected role's access is never a candidate for the answer. Production identity and permissions integration remain separate work.

Observed attack

Poisoned content induced a simulated email action addressed to an attacker. The action gate blocked it before execution.

Read technical note

61 deterministic security and retrieval evaluations cover eight documented threat classes and retrieval behavior. CI exercises three supported combinations of Qdrant or pgvector backends with native or LangGraph runtimes, without model calls. Per-session and per-IP spend caps bound model cost. The demo uses a role switcher and simulated side-effecting tools; real-world effects cannot execute through those simulated tools.

Telehealth client delivery

Patient intake, scheduling, payment collection, and transactional email delivered around existing practice software. The engagement was delivered through AIntellect, a part-time solutions practice I co-founded.

Vouch

A Houston restaurant app for choosing where to eat from recent recommendations. Newer vouches carry more weight, the whole Top 10 is free, and membership never adds voting power. I directed and verified its AI-assisted implementation across Flutter, Firebase, subscriptions and linked sign-in, and released it on iOS and Android.

Porter

A voice-intake demo on a real phone line, for collecting request details, classifying urgency and confirming what the caller said. Replay recordings bind to a hash of the prompt, so changed behavior cannot inherit a stale pass. Booking is simulated; a person handles fulfillment.

Roster

Production operations software deployed at a permitted transitional-housing facility, with authorization enforced beyond the interface and a per-facility retention date defaulting to five years.

Junta

A live home-improvement marketplace with a Houston roofing-first focus. I co-founded Junta with Davia Hudson, who leads business direction. I lead engineering, and we both work on the launch. Homeowners compare sealed bids on a shared project scope before choosing a contractor. Its payment-race correction prevents a losing request from cancelling a shared payment created by the winning request.

Sabi

A private football prediction beta, co-developed with independent approval on every merged web pull request. The work includes server-owned prediction boundaries, provider-data integrity, and collaborator-reviewed mobile changes.

Standsong

A football songbook app I am preparing for its first public release. The work includes offline matchday access, community Call-Ups, reviewed evidence labels, and native media tooling in Swift and Kotlin. Song popularity stays separate from proof of where a chant has been sung.

Reckon

Analytics with dependency-aware freshness, a read-only Postgres role scoped to the marts schema, and Prometheus, Grafana, and Loki observability. A read-only Model Context Protocol server exposes bounded queries over the reporting marts.

03 · About

My work often crosses teams.

Over nine years in production software, I have worked across code, data, infrastructure, support, and customer experience. At Vestmark, one investigation helped reduce an hours-long client file-delivery workflow to roughly 10 to 15 minutes. Since July 2025, I have also worked part-time through AIntellect, a solutions practice I co-founded with Ben Bolaji. Across that work and my product builds, I stay accountable for behavior through client constraints, real calls, live operations, collaborative review, and release decisions.

For my AI-assisted projects, I specify the behavior, review the implementation, test important failure paths, and approve delivery. I also maintain a shared engineering workflow for project memory, explicit handoffs, and independent review, so another agent can pick up the work without treating a recap as proof.

How I build with AI

SpecifyI write the behavior and limits first.

BuildAn AI agent implements it and keeps a record.

ChallengeA second model reviews it adversarially.

VerifyI test the failure paths and decide what ships.
