MercivenWe build, ship and manage custom data solutions.
Pipelines, lakehouses, and the apps and AI agents that run on them. We prove the numbers are right, then keep it all running in production.
Open any project and use the app.
Each case study starts with the running product, with its numbers beside it.
Offline-first inventory for TT Global
Store staff scan QR codes and record stock on a phone, even when the network drops.
Pharmacy data feed migration
A 165-column patient status and dispense feed moved from SQL Server stored procedures to Databricks, and proved row for row against the legacy output before cut-over.

Four practices, one team accountable for each delivery.
Full-stack products
Web applications with payments, authentication and real users, from database to interface.
02Applied AI
LLM features that are grounded and tested: the model drafts, typed rules and computed results decide.
03Data engineering
Pipelines, lakehouses and dbt models on Databricks, Snowflake and Azure, including healthcare data.
04Automation, QA & immersive
Test suites for money-moving systems, operations automation, and data from XR experiences.
The model drafts. Typed rules and computed results decide.
AI that can't invent numbers
Language models propose; code checks. Figures come from calculations, and any AI sentence that cites something that doesn't exist is rejected.
Proven against what you have
New pipelines are compared with the old system column by column before anyone switches over.
Money handled like money
Verified webhooks, idempotent ingestion, row locks and integer kobo. Retries and concurrent payments are tested, not hoped about.
You talk to the people who build it
No hand-offs. Based in Lagos (UTC+1): a full day shared with the UK and Europe, and your morning in the US.
