Challenges
Financial institutions face a specific set of technology problems — regulatory compliance, legacy infrastructure, security at scale, and the pressure to move faster than competitors without taking on unacceptable risk. We understand these constraints because we've built in this environment.
We take pride in this:
Core banking systems built on decades-old architecture that can't support modern APIs, real-time processing, or the integration requirements of a digital-first product strategy.
Operating across the US and EU means navigating PCI-DSS, GDPR, PSD2, MiFID II, and sector-specific compliance requirements simultaneously — with consequences for getting it wrong.
Financial data is the highest-value target for attackers. Every layer of the stack — authentication, data storage, API design, third-party integrations — needs to be built with security as a design constraint, not an afterthought.
Neobanks and fintech challengers move fast. Traditional institutions and mid-market financial companies need to accelerate digital delivery without sacrificing the stability and compliance their clients depend on.
Solutions
We build across the full financial technology stack — from core platform modernization and regulatory compliance architecture through to AI-powered products and customer-facing digital experiences.
Custom core banking platforms and platform modernization — built on modern, API-first architecture that supports real-time processing, third-party integrations, and the scale your institution requires.
End-to-end payment platform development — card processing, digital wallets, open banking payment flows, and payment gateway integrations built to PCI-DSS standards and designed for high-volume reliability.
Credit scoring models, fraud detection systems, algorithmic trading tools, and AI-powered customer service — practical AI built into financial products where it creates measurable business value.
We design and build systems that are compliant by architecture — not by bolt-on. GDPR data handling, PSD2 open banking APIs, AML transaction monitoring, and audit logging built into the foundation.
Real-time dashboards, regulatory reporting systems, and financial data pipelines that give your leadership team and your regulators the visibility they need — accurate, on time, and auditable.
Mobile banking applications, customer onboarding flows, and digital banking interfaces that match the experience customers expect from modern financial services — secure, fast, and frictionless.
Obsessed with delivery. Every project, every time.
Case studies
We delivered end-to-end development for DISH by Metro's Dish Pay platform — a digital payment and ordering system processing high volumes across the US restaurant market, built for compliance, reliability, and scale.
We partnered with Banca Transilvania — one of Romania's leading banks — to deliver engineering teams and digital platform development, supporting their digital transformation at the pace and quality a major financial institution demands.
Why Mejix for Finance & Banking?
From early-stage fintech startups building their first product to established banks modernizing legacy infrastructure — we deliver the same standard of engineering, compliance awareness, and delivery accountability to every engagement.
We take pride in this:
We design systems with regulatory requirements as a constraint from the architecture phase — not as a review step at the end. PCI-DSS, GDPR, PSD2, and AML requirements are part of the technical blueprint from the first sprint.
Authentication, encryption at rest and in transit, role-based access controls, audit logging, and penetration testing are standard on every financial platform we build — not premium add-ons.
Every project has a US-based project manager who owns the client relationship, delivery timeline, and escalation path. You have a single point of contact who is accountable — not a team in another timezone you have to chase.
Banca Transilvania, Dish by Metro, Dine Market — active financial sector clients who trust Mejix with platforms that process real money, real transactions, and real customer data. Not case studies. Live systems.
