Senior engineers with 12–15 years of enterprise experience building platforms that handle sensitive financial data at scale. Client portals, dashboards, payment processing, open banking, and fintech MVPs — built with security and compliance as first-class requirements.
Discuss Your Project →Financial software demands a higher standard of engineering — in security, accuracy, auditability, and reliability. We build to that standard from the first line of code.
Secure, role-based portals for financial advisors, wealth managers, and accountants — document vault, portfolio views, messaging, goal tracking, and meeting scheduling.
Real-time and near-real-time dashboards for transaction monitoring, P&L, cash flow, KPI tracking, and executive reporting — with drill-down and export.
Stripe, Adyen, GoCardless, and open banking integrations. Split payouts, recurring billing, refund management, and reconciliation — PCI scope-reduced by design.
Automated invoice generation, approval workflows, payment collection, overdue chasing, and integration with accounting software like Xero or QuickBooks.
Bank feed aggregation via TrueLayer or Yapily, transaction categorisation, cash flow forecasting, and account verification for onboarding.
Audit logging, logical access controls, encryption at rest and in transit, vulnerability management documentation, and security event monitoring.
End-to-end fintech product builds — from architecture and compliance design through to App Store submission or production deployment. Built to survive due diligence.
Risk profiling questionnaires, suitability assessment tools, scenario modelling, projection calculators, and report generation for regulated advisory workflows.
Generic fintech platforms give you speed at the cost of control. You are locked into their data model, their pricing per user, their API limits, and their compliance posture. When regulators ask questions, you are dependent on a vendor's answers. Custom software means you own the architecture, you own the data, and you control the compliance narrative.
Enterprise consultancies bring large teams, long timelines, and significant overhead costs. Financial software often does not need an army — it needs a small number of very experienced engineers who understand security, financial data modelling, and regulatory risk. That is what we are. You get senior hands, not a team of fresh graduates supervised by a partner.
Financial software security is not a one-person job. Access control, encryption, audit logging, payment integration, and frontend all need to be designed together by people who understand the full threat model. A freelancer optimising their module without seeing the whole system is a security risk. We design and build the whole thing.
Fintech projects often begin as an MVP build and evolve through product scaling engagements as compliance and audit needs grow. See our full set of capabilities, read about how we work, or learn more about the team behind The Yellow Labs.
We bill hourly from $40/hr. A client portal or financial dashboard typically runs 100–300 hours. A full fintech MVP with payment processing, user management, and reporting generally falls between 300–700 hours. Compliance-specific architecture work (SOC2 controls, audit trails, encryption) adds 50–150 hours depending on scope. We provide detailed weekly hour reports.
Yes. We design systems with SOC2 Trust Service Criteria in mind: logical access controls, audit logging, encryption at rest and in transit, vulnerability management processes, and change management documentation. We do not run your SOC2 audit, but we build the technical infrastructure your auditors will evaluate. We can also produce the system description documentation that assessors require.
We integrate Stripe (including Stripe Connect for marketplaces and Stripe Treasury for embedded finance), Braintree, Adyen, Worldpay, GoCardless for direct debit, and open banking APIs via providers like TrueLayer or Yapily. We follow PCI DSS scope-reduction principles — raw card data never touches your servers. Payment reconciliation, split payouts, and refund management are all areas we handle.
Yes. Financial advisory portals are a core area for us — secure document vault, portfolio summary views, risk questionnaires, goal tracking, meeting scheduling, and secure messaging between advisor and client. We build these with role-based access so advisors, compliance officers, and clients all see only what they are permitted to see, with a full audit trail.
Yes. We have built dashboards with WebSocket-based live updates, real-time trade or transaction feeds, and high-frequency metric panels. We also build async dashboards where near-real-time (seconds to minutes) is sufficient and more cost-effective. The right approach depends on your data volume and latency requirements — we help you make that call.
A focused fintech MVP — for example, a client portal with document management, a basic dashboard, and Stripe payment integration — typically takes 10–20 weeks. A more complete product with open banking, complex reporting, multi-tenant access, and compliance infrastructure runs 20–40 weeks. We always recommend building a tight MVP first and expanding based on real user feedback.
