Gateway design and modernization
Define service boundaries, transaction contracts, deployment paths, and staged migrations for payment gateways that must change while remaining in service.
Payments
Payment infrastructure that stays accountable.
A payment is more than an API call. It is a stateful operation across providers, internal systems, ledgers, and people who must explain what happened when the paths disagree.
Where we work
Own the transaction from request to reconciliation.
brimtech designs and modernizes payment infrastructure with authorized financial institutions and providers. We build the software and integration layer that makes transaction behavior visible, repeatable, and recoverable.
Provider integration
Connect banks, mobile money services, processors, and internal systems through explicit contracts, authentication, validation, callbacks, and recovery behavior.
Transaction lifecycle
Model initiation, pending states, authorization, completion, failure, reversal, expiry, and reconciliation without treating uncertain states as final.
Routing and orchestration
Route payment requests by provider capability and operating policy while keeping retries, idempotency, timeouts, and fallback behavior explicit.
Ledgers and reconciliation
Connect operational transaction records to obligations, provider reports, internal ledgers, and settlement evidence so differences enter a managed queue.
Production operations
Instrument APIs and workflows, expose failure states, support incident handling, and give operators the evidence needed to resolve unmatched transactions.
State and recovery
The response is not the transaction.
A timeout does not prove failure. A success callback does not by itself prove reconciliation. We keep the request, provider state, internal state, obligation, and reconciliation evidence separate enough to resolve disagreement.
