Description

We build and modernize the systems that move money and data, for fintechs, financial institutions and tech companies. Typical work includes core banking and payment platforms, middleware and last-mile integrations connecting legacy systems to modern APIs, migration of monoliths to cloud-native services, and dedicated squads embedded in a client's engineering team. We have been doing this since 2002. Our engineers are in-house rather than contracted per project, working from our delivery center in Brazil with an office in Miami, under ISO 27001 and ISO 27701 certification and AWS and Google Cloud partnerships.

Description

We build AI into systems that already carry real transaction volume, in regulated environments where a mistake has a cost. Our work covers AI agents running in production, document and invoice reading with computer vision, fraud detection and risk scoring, conversational support that resolves without escalating to a human, and AI-led modernization of legacy platforms. Recent work includes an agent stack that resolves 80% of support tickets with no human agent, a computer vision engine reading bills at 98.5% accuracy, and a credit engine that approves in under 3 seconds. We deliver with in-house senior engineers from our delivery center in Brazil and an office in Miami, under ISO 27001 and ISO 27701 certification.

Description

We design the interfaces people use to move money, file claims, approve credit and run operations, where a confusing screen becomes a support ticket. Our work covers user research and journey mapping, reusable design systems that survive the handoff to engineering, dashboard and back office design, and accessibility for regulated environments. Design does not stop at the prototype here. The same team carries it into production, which is why our redesigns ship instead of staying in Figma.

Description

We build the apps people trust with their money: wallets, remittance, lending, payments and digital banking, plus the field and retail apps that keep operations running offline. Our work covers native and React Native builds from a single codebase, onboarding and KYC flows, in-app payment and card issuance integrations, offline-first sync for teams working without signal, and release management on both stores. We have shipped apps carrying real transaction volume in regulated markets, under ISO 27001 and ISO 27701 certification.

Description

We build the web platforms that run a business from the inside: member and investor portals, back offices, operational dashboards, and the admin layers where support and compliance teams actually work. Our work covers single page applications in Angular and React, Java and Node back ends, API and system integration, progressive web apps, and the DevOps pipeline that keeps releases predictable. Most of what we build sits on top of systems that cannot stop, so we plan migrations and releases around uptime, under ISO 27001 and ISO 27701 certification.

Description

This is where a project starts before anyone commits to building it. We run discovery with the people who will use the system, map the current architecture and its constraints, and build a proof of concept against real data instead of a slide. The output is a decision: what to build, what it will cost, what it touches, and in what order. Most of our AI and modernization work starts here, as a short scoped engagement that ends with a plan the engineering team can execute.

Description

We put product people next to the engineering team, not above it. Our work covers discovery and roadmap definition with the client's stakeholders, writing and prioritizing the backlog, running delivery in short cycles with clear acceptance criteria, and keeping the product moving after launch through lifecycle and release planning. This is the layer that keeps a long engagement honest: what shipped, what changed because of it, and what comes next.

Description

We build the data layer underneath the product, not the dashboard on top of the marketing site. Our work covers ingestion and ETL pipelines that normalize data from systems that were never meant to talk to each other, data migration out of legacy databases, operational and executive dashboards, and the modeling that turns raw records into indicators a team can act on. This is usually the step before AI. A model is only as good as the pipeline feeding it, and most of the work lives there.
