Financial Software DevelopmentWhere Every Cent Must Reconcile.
We build fintech products and financial tooling — payment integrations, lending workflows, KYC onboarding, dashboards and reconciliation systems — with the correctness-first engineering money demands.
Money software is correctness software.
Financial software has no "mostly works": amounts are integers, every mutation is idempotent, every state change leaves an audit trail, and reconciliation catches what tests miss. That discipline - typed code, double-entry thinking, deterministic retries - is the core of how we build for fintech startups and finance teams, from payment flows to the back-office tools nobody sees but everybody depends on.
Fintech work we take on.
From customer-facing flows to the operational tooling behind them.
Stripe and payment-gateway integrations, subscription billing, payouts, webhooks handled idempotently — money movement that survives retries and race conditions.
Application journeys, KYC/identity-verification integrations, decision workflows and document handling with full traceability.
Transaction dashboards, ledger views and reconciliation tooling — see our data analytics services.
Document extraction, support assistants and analyst copilots built on retrieval-grounded AI — cited answers, never improvised numbers.
Security posture matters doubly in fintech: encryption everywhere, least-privilege access, your infrastructure, and security testing as part of delivery — with honest language about which compliance obligations (PCI DSS scope, licensing) sit with your organization rather than the codebase.
Common questions.
Anything not covered here, ask us directly — we answer within 24 hours.
Do you handle PCI DSS compliance?
We architect to minimise your PCI scope - card data stays with the payment provider (Stripe, Adyen) through tokenisation, so your systems never store card numbers. Where PCI obligations do apply to your organization, we build and document the technical controls; the certification process itself is organisational.
How do you prevent money bugs?
Integer arithmetic for amounts, idempotent mutations, double-entry style ledgers where movements matter, exhaustive typed state machines, and reconciliation jobs that independently verify totals. Plus boring, reviewed code - excitement belongs in the product, not the ledger.
Can you work with our bank or payment-provider APIs?
Yes - gateway and banking-API integrations are scoped in discovery, where we confirm sandbox access and feasibility before quoting. Webhook reliability and failure handling get designed up front, not patched later.
Who owns the code and where does financial data live?
You own all code and IP in writing from day one, and data lives in your cloud accounts in your chosen regions. We operate under NDA with least-privilege access that you can revoke at any time.
