Fintech Software Development Company
PCI-compliant payment, trading, and banking infrastructure with AI risk, fraud, and personalization layered on top — built by engineers who have shipped production fintech.
PCI-compliant payment processing, wallet infrastructure, and checkout flow optimization.
Real-time trading systems with low-latency market data processing and order management.
Core banking integrations, mobile banking apps, and open banking API platforms.
AML, KYC, and regulatory compliance systems that reduce risk and operational overhead.
Custody, on-ramps, and trading infrastructure for regulated digital-asset products with clear separation of duties.
ML fraud detection, transaction monitoring, and credit models tuned for fintech risk profiles and regulator scrutiny.
Fintech software fails in the places users never see: a reconciliation job that drifts by a cent, a KYC flow that stalls at 80% completion, a ledger that can't prove its own balance during an audit. Codieshub builds fintech platforms where correctness, compliance, and uptime are designed in from the first commit — not bolted on after a regulator asks.
We've shipped digital banking, lending, payments, wealth, and crypto products for companies that move real money at scale: a flagship regional bank's core platform, an investor-discovery marketplace, a capital-markets workflow tool, and a hardware-wallet ecosystem. Senior nearshore engineers, U.S.-aligned hours, and a delivery process built for SOC 2 and audit trails — so your roadmap moves without your risk surface growing.
Most fintech teams don't lack ideas — they lack engineering capacity that understands money. Generalist dev shops ship features that demo well and then leak edge cases: double-spends under load, idempotency gaps in payment retries, PII sitting somewhere it shouldn't. Every one of those becomes a compliance finding or a customer-trust event.
We staff fintech engagements with engineers who've built ledgers, payment rails, and KYC/AML pipelines before. Week one is a data-flow and threat map — where money and PII move, where they're stored, who can touch them. We build the integration and compliance layer before the UI, deploy to your own cloud account by default for regulated data, and ship with audit logging, idempotency, and reconciliation as first-class concerns.
Platforms that are structured to pass technical due diligence and regulatory review, not just user testing. We build digital-banking and payments products with the architecture reviewers' checklist in mind from day one — fewer incidents after launch, faster audit cycles, and a codebase that compounds on itself instead of accruing compliance debt.
A senior fintech engineer scopes your build — compliance, integrations, and timeline — in one call.

Four ways to work with us — from surgical staff augmentation to fully managed delivery. All models share the same senior-first talent bench.
Full-time engineers embedded in your team for long-running engagements.
Explore Dedicated Teams↗Add senior specialists to an existing team — vetted, onboarded, and up to speed in weeks.
Explore Staff Augmentation↗Managed fixed-scope projects with a committed timeline and deliverables.
Explore Project Delivery↗Fractional senior technical leadership for architecture, hiring, and strategy.
Explore Virtual CTO↗Why Codieshub
The shortlist we get asked about on every call — what actually separates Codieshub from a dev shop.
SOC 2-aligned process, HIPAA where it overlaps health-fintech, audit logging and access controls in from day one — not a pre-audit scramble.
Ledgers, payment rails, KYC/AML, settlement, and reconciliation — patterns our team has shipped, not learned on your dime.
Regulated workloads deploy to your AWS/GCP account by default, with cross-border data-residency handled in week-one architecture.
Idempotent payment flows, exactly-once processing, and reconciliation jobs that prove their own balances — tested against the edge cases that cost real money.
Nearshore engineers on U.S. hours — incident response and code review happen live, which matters when the system moves funds.
Architecture diagrams, security posture, and engineering-risk docs that reviewers for seed, Series-A, and bank partnerships actually accept.

Process
Our engineers are not freelancers, and we are not a marketplace. Dedicated Codieshub seniors, seated with your team.
Before kickoff
Pre-kickoff technical and strategic review.
Before a single line of code, we sit with your team to align on stack, constraints, and what success looks like. Our VP Eng, CTO, and senior leads join — not a sales engineer.

Questions
The questions we get on every intro call — answered without the marketing gloss.
Yes. We default to SOC 2-aligned engineering — audit logging, least-privilege access, encrypted-at-rest data, and change-management trails. For card flows we build to PCI-DSS scope-minimization (tokenization, no raw PAN in your systems), and we've delivered against the technical questionnaires bank and BaaS partners send during onboarding.
