AI Infrastructure

View project ↗

ModelRail

A production AI gateway that gives developers one API for routing, failover, usage limits, and billing across multiple models — launching first for developers in Nigeria.

Built a two-tier routing system that picks the right model from static mapping plus lightweight heuristics, with no added latency from an extra LLM call.

Workload-alias system (auto, chat, reasoning, code, tools) so apps call a stable alias instead of a specific model.
Rate limits and monthly spend caps with clear error responses to prevent runaway usage and surprise bills.
Prepaid credit wallet built to remove payment friction for developers in Nigeria.

Payments Infrastructure

KrownPay

Backend services, cloud infrastructure, and transaction workflows for a production payments platform.

Led the move from a monolith to event-driven microservices, improving reliability and responsiveness for payment processing.

30% AWS infrastructure cost reduction from adding spot instances to EKS while improving scaling.
Real-time blockchain transaction monitoring across Solana, Ethereum, and Polygon.

AI & Data Systems

Resonance Holdings

AI-driven market intelligence products — data exploration, relationship mapping, and contextual insights.

Designed and tuned Neo4j graph models and Cypher queries for relationship-based search, filtering, and analytics.

Integrated proprietary and third-party AI models into the data pipeline to improve recommendations.
Set up AWS infrastructure (EKS, S3, Lambda, API Gateway) for secure, scalable deployments.

Engineering approach

How I work

Build reliable systems

Led the move from a monolith to event-driven microservices at KrownPay, improving reliability and responsiveness for live payment processing.

Design pragmatically

ModelRail's routing picks the right model from static mapping plus lightweight heuristics — accurate enough without the latency of an extra LLM call.

Own systems end-to-end

At Resonance Holdings, owned the stack from Neo4j data modeling and API design through to the AWS infrastructure serving it.

Optimize against real constraints

Rewrote database queries at Montra Interactive for a 30% gain in retrieval speed, and cut KrownPay's AWS costs 30% with right-sized, spot-backed infrastructure.
