What to expect

How we work with you

Source code, ML models, design files, infrastructure-as-code, documentation. Yours from day one, in your GitHub organization. No licensing strings, no per-seat surcharges.

UI/UX designers discussing a digital design

Domain depth

Engineers Who Know Finance

Most of our fintech engineers have spent years on banking, payments, or trading systems. You won't be paying for a generalist team to learn ISO 20022 or KYC workflows on your project.

Rectangle 1912

Scope Clarity

Honest Scope Conversations

If your timeline is tight or your budget doesn't match the scope, we say so before you sign anything. We'd rather pass on a project than agree to one we can't deliver well.

Rectangle 1912

Compliance

Compliance Considered Early

PCI DSS, PSD2, GDPR, SOC 2, and AML/KYC requirements are factored into the architecture from the first sprint. Compliance teams join our discovery sessions, not just our pre-launch reviews.

Demos Every Two Weeks

You see working software at the end of each sprint not slide decks describing what we plan to build. If something's not working, you find out early, while changes are still cheap.

Access to engineers

Direct Engineering Access

You talk to the engineers building your product. Not just account managers. Slack, email, or call whatever works for your team's rhythm and time zone.

What we focus on

Where we spend our engineering time

Six things fintech teams typically tell us they need help getting right. Where we focus our engineering hours, regardless of the specific project.

Vector (9) 01

Fraud signals that are useful

Tuning detection so analysts trust the alerts and customers don't get blocked for normal behavior. Quiet improvement, not flashy dashboards.

Vector (10) 02

Decisions that happen in time

Credit checks, onboarding, and risk scoring that complete while the customer is still on the page. Architecture and integration work that earns its keep.

Vector (11) 03

Costs that track with usage

Cloud bills, third-party fees, and AI inference costs that scale with the customers you're serving not ahead of them. We watch this carefully.

Vector 04

Compliance built into the workflow

Audit logs, transaction monitoring, and reporting that produce themselves as platform runs. So compliance teams aren't manually reconstructing things.

Vector (13) 05

Migrations that don't break things

Phased modernization where new and old run in parallel until you're confident. Cutovers happen on a Tuesday morning, not a tense Sunday at 2am.

  • » High-fidelity UX in Figma web, mobile, dashboard, and admin interfaces.
  • » System architecture covering data models, APIs, integrations, auth, and compliance.
  • » Agile sprints with weekly working demos and live client feedback loops.
vector icon img 14

UX, architecture, build, and ongoing review with working demos every two weeks.

Step 3

Deploy & evolve

  • Frame
  • » Deployment to AWS, GCP, or Vercel with CI/CD pipelines and zero-downtime releases.
  • » Observability with Datadog, Sentry, or Grafana live from day one tracing, errors, and performance.
  • » Security hardening, access controls, and compliance-ready audit logging.

Questions

Fintech development FAQs

Structured for AI search engines and Google rich results. Implement FAQPage JSON-LD.

Most fintech MVPs we ship run 12–20 weeks from kickoff. Larger platform builds run 9–24 months in phased rollouts. Integrations and AI features usually ship in 6–10 weeks. After a 30-minute discovery call we share a milestone-driven timeline, and you can decide from there.

Yes. We've integrated with Mambu, Temenos, Finacle, Avaloq, FIS, Fiserv, and a number of legacy mainframe cores. We rarely recommend rip-and-replace. Most of the modernizations we do build modern surfaces and AI layers on top of cores that are still doing their job.

Yes. We've built for crypto exchanges, custody platforms, on-chain analytics tools, stablecoin issuers, and tokenized RWA platforms. We bring MiCA, Travel Rule, and VASP compliance experience alongside Solidity, ethers.js, and Fireblocks integration depth.

You do fully, from day one. Source code, ML models, design files, infrastructure-as-code, and documentation. Full IP assignment is signed before sprint one. Your codebase lives in your GitHub organization, operable by your team after handoff.

Fixed-scope projects, dedicated teams, nearshore development centers, and time-and-materials. Most fintech engagements run as dedicated teams with fixed milestones. We'll recommend a model during discovery based on your scope, timeline, and how you prefer to manage risk.
