Services

Four things, in the order people usually ask for them.

Financial systems

Ledgers, multi-currency accounting, settlement and reconciliation, escrow and payment flows. Includes the parts that are easy to skip and expensive to add later: an audit trail that can answer a dispute, and balances that reconcile to the cent.

Distributed systems

Designing and repairing services that span machines — queues, replication, consensus, retries and the failure modes that only appear under load. Often this starts as “it works, but we do not trust it”.

Applications

Cross-platform apps from a single codebase — Android, iOS, web, desktop — including push notifications, real-time calling, end-to-end encryption and behaviour when the network is not there.

Architecture review

A short, bounded engagement: read the system, talk to the people running it, and hand back what will break first and what it would take to fix. Useful before a funding round, an audit, or a rewrite you are not sure you need.

Engagements

Review

One to two weeks, fixed price, written findings.

Project

Scoped and quoted up front, delivered in working increments.

Ongoing

Retained time each month for systems that need a hand on the tiller.
