Systems integration and legacy modernisation
We connect the systems you already rely on — payments, banks, messaging, identity and older applications — so data moves on its own and reconciles, and we modernise legacy systems in phases instead of risky switch-overs.
Sound familiar?
- 01Staff re-type the same data into two or three systems.
- 02Payments arrive by mobile money or bank and are matched to records by hand.
- 03An old system is too risky to change and too important to switch off.
- 04Data moves between systems overnight in spreadsheets, and errors surface weeks later.
What we do
API design and development
Well-documented, versioned APIs that let your systems and partners exchange data safely.
Payment integrations
Mobile-money and bank integrations — including M-Pesa collections, confirmations and payouts — with automatic reconciliation.
Messaging integrations
SMS, email and push notifications sent reliably, with delivery tracked and retried when providers fail.
Event-driven integration
Systems that react to each other in real time through a reliable message backbone, rather than nightly batches.
Phased legacy modernisation
The old and new systems run side by side while records, workflows and users move across in stages — so operations never stop.
Data migration
Migration with reconciliation reports, so you can prove nothing was lost or silently changed.
What you get
- Integration architecture
- Documented APIs and connectors
- Reconciliation and monitoring
- Migration plan and cut-over runbook
Every engagement runs in short increments: you see working software regularly, scope changes are agreed before they are made, and handover includes documentation and training. How we work.
Tools we use in production
- REST & OpenAPI
- Safaricom Daraja (M-Pesa)
- RabbitMQ / Celery
- Transactional outbox pattern
- OpenTelemetry
The technology serves the problem. We recommend tools based on your needs and the team who will maintain them.
Questions we often hear
Can you integrate M-Pesa into our existing system?
Yes. We build M-Pesa collections, confirmations and payouts on the official Daraja API, including automatic matching of payments to records.
Do we have to replace our legacy system?
Not necessarily. Sometimes integrating around it is the right first step. When replacement is right, we plan a phased migration so the old system keeps running until the new one is proven.
How do you make sure a migration is complete?
Every migration produces reconciliation reports comparing source and destination, and we agree acceptance criteria before cut-over.
