Loubby AI
Context
Loubby is DivVerse’s AI-powered talent, hiring, payroll, and remittances platform. I joined as a senior full-stack engineer and owned work across product surfaces, AI workflows, identity, and the services that keep payroll correct.
Problem
Hiring, assessment, onboarding, and payroll are usually separate products. For companies operating across Africa, that fragmentation becomes operational cost - and AI bolted on afterward rarely survives production.
What I owned
- AI assessments and candidate matching
- Hiring pipelines, onboarding, PIPs and KPIs
- Payroll, deductions, taxes, timesheets
- LLM-generated job descriptions and scoring
- 3MTT national AI job marketplace
- OAuth 2.0 / JWT and .NET Core microservices
Engineering challenge
Ship AI-assisted hiring and evaluation that holds up at hundreds of thousands of users, while payroll and identity remain correct, auditable, and operationally boring.

Context
Loubby is DivVerse’s AI-powered talent, hiring, payroll, and remittances platform. I joined as a senior full-stack engineer and owned work across product surfaces, AI workflows, identity, and the services that keep payroll correct.
What I owned
Hiring pipelines, AI assessments, candidate matching, onboarding, PIPs and KPIs, LLM-generated job descriptions and scoring, payroll and timesheets, and the 3MTT national AI job marketplace. Auth is OAuth 2.0 / JWT. Services include .NET Core microservices alongside Node.
Scale
The platform serves 200,000+ active users and 2,500+ companies. Performance work on the React surfaces - memoization and render discipline - reduced CPU by around 35%. That is the kind of work that only shows up when the product is already in production.
Outcome
A production talent and payroll platform used by 200,000+ people and 2,500+ companies, including the 3MTT national marketplace - with measurable frontend performance work (~35% CPU reduction).
