What to expect

How we work with you

Six things that show up consistently across our fintech engagements. Not promises — just how we tend to work.

Industries Cover

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.

Industries Cover

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.

Industries Cover

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.

Industries Cover

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.

Industries Cover

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.

Industries Cover

You Own What We Build

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.

Our services

What we build for you

Nine areas where fintech teams hire us. Each can be a single engagement or part of a larger build.

Discovery & Architecture
Stakeholder workshops, regulatory mapping, technical feasibility, and a reference architecture. You leave with a fixed-scope proposal, a roadmap, and a realistic timeline.
Custom Platform Engineering
Frontend, backend, data, and DevOps for new fintech products. Cloud-native on AWS, Azure, or GCP — with infrastructure-as-code and observability from sprint one.
AI & Data Engineering
Fraud scoring, credit decisioning, document processing, and customer copilots. Includes feature stores, model deployment, drift monitoring, and human-in-the-loop review.
Core Modernization
Phased migration off mainframe, AS/400, or aging T24 cores. Strangler-fig patterns let new and old systems run in parallel until you're ready to decommission components.
Digital Wallet Engineering
Stored value, P2P transfers, bill pay, multi-currency support, and tokenization. Apple Pay, Google Pay, and regional wallet integrations included where relevant.
API Integration Layer
Open banking (PSD2, FAPI), ISO 20022 messaging, payment rail integrations, KYC providers, and partner APIs — built once, documented properly, reused across products.
Legacy System Optimization
Performance tuning, technical debt reduction, observability for systems you can't yet replace. Buy yourself time and stability while planning a longer migration.
IoT & Hardware Integration
ATM firmware, POS terminals, biometric readers, smart card devices, and self-service kiosks. Secure provisioning, OTA updates, and field-telemetry dashboards.
Crypto & Web3 Engineering
Exchange infrastructure, custody integration, stablecoin payment rails, on-chain analytics, and Travel Rule compliance. For VASPs and fintechs adding digital-asset capabilities.

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.

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.

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.

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.

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.

04

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.

Not sure which path fits your project?

Tell us where you are and we'll recommend the right approach — honestly.

Work

Real Software Projects We've Shipped

Real scenarios where founders, operators, and enterprise teams brought us in to build software that shipped to production:

Where we go deep

Fintech Sub-Sectors We Know Well

Six fintech sub-sectors where most of our recent work has happened. If your project sits inside one of these, we can usually start with shipped-product context, not a learning curve.

Retail & Commercial Banking
Mobile and online banking, account servicing, treasury management, and SME banking portals. Comfortable on Mambu, Temenos, or building fully custom — depending on what fits your business.
Capital Markets & Trading
OMS/EMS, FIX gateways, market surveillance, and post-trade automation. Built for institutional desks, brokers, and trading platforms with low-latency requirements.
Payments & Cards
Issuing, acquiring, real-time settlement (FedNow, SEPA Instant, UPI), 3DS, tokenization, and cross-border FX. PCI DSS-aligned design across the payment perimeter.
Wealth & Asset Management
Robo-advisory, model portfolios, performance attribution, ESG analytics, and investor reporting. For RIAs, family offices, and institutional asset managers.
Crypto, Web3 & Digital Assets
Exchange and custody infrastructure, on-chain analytics, MiCA-aligned compliance, Travel Rule, stablecoin issuance, and tokenized real-world asset platforms.
RegTech & Compliance
AML, KYC, sanctions screening, transaction monitoring, regulatory reporting (FINREP, COREP, CCAR, MiFID II), and audit trail systems with cryptographic integrity.

Process

How Our Custom Software Development Process Works

Every software project follows a clear three-phase lifecycle, broken into execution sprints underneath. Full builds typically run 8 to 16 weeks. Internal tools and bounded projects often ship in 4 to 8 weeks.

Phase 1

Consult and Align

Discovery, regulatory mapping, and scope. You leave with a fixed-scope proposal.

Phase 2

Design and Engineer

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

Phase 3

Deploy & Evolve

Cloud deployment, observability, and ongoing iteration as the platform earns traffic.

What Our Clients Say

Questions

Custom Software Development FAQs

Structured for AI search engines (ChatGPT, Gemini, Perplexity, Claude) and Google rich results. Implement FAQPage JSON-LD for every question.

How long does a typical fintech project take?

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.

Compliance is part of the architecture, not bolted on at the end. Every engagement starts with a regulatory mapping for your jurisdictions. We work under ISO 9001:2015, run security scans on every commit, and align our operations to SOC 2. Compliance specialists from our team join your discovery sessions where it makes sense.
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.
