Web platforms, mobile apps and internal tools that fit how your company actually works — and keep working as it grows. Margins designs, builds and modernises production software around your operations — from product discovery and UX to backend systems, integrations and cloud infrastructure. - Talk to an engineer - [See our work](https://margins.agency/client-outcomes) Production software ## The interface is only one part of the product. Software that lasts needs more than screens. A product can look finished in a demo and still fail once real people depend on it. It needs a data model that reflects how the business works. It needs to connect to the systems already in place. It needs to be secure, fast and accessible. Releases need to be safe. Failures need to be visible before customers notice them. And the whole thing needs to stay maintainable as the team and the business change. That is the engineering problem we solve. 1. 01 **Experience** UX research · Design systems · Accessibility · Interfaces 2. 02 **Applications** Web · Mobile · Desktop · Internal tools 3. 03 **Backend** APIs · Services · Business logic · Data models 4. 04 **Integration** ERP · CRM · Internal systems · Third-party platforms 5. 05 **Infrastructure** Cloud · Private cloud · On-premises · Infrastructure as code 6. 06 **Operations** CI/CD · Testing · Observability · Security Software engineering capabilities ## The right build for the problem. 01 / 06 ### Web Platforms & Portals Customer-facing platforms, portals and marketplaces built to perform under real traffic. - Customer portals - Marketplaces - SaaS products - Self-service platforms - Headless commerce - Performance & SEO 02 / 06 ### Mobile Apps Native and cross-platform apps for customers, employees and field teams. - iOS & Android - React Native - Offline-first - Push & messaging - App Store releases - Device integrations 03 / 06 ### Internal Tools & Operations Software Software that replaces spreadsheets, email chains and manual handoffs inside the operation. - Back-office systems - Admin dashboards - Workflow tools - Role-based access - Reporting - Field service apps 04 / 06 ### APIs & Integrations Connect the systems the business already runs on, so data moves without re-keying. - REST & GraphQL APIs - ERP & CRM integrations - Payments - Event-driven systems - Third-party platforms - Data synchronisation [Explore Enterprise Integrations](https://margins.agency/technology/enterprise-integrations) 05 / 06 ### Legacy Modernisation Move ageing systems onto a modern stack without stopping the business that depends on them. - Re-platforming - Incremental migration - Monolith to services - Data migration - Cloud migration - Technical debt reduction 06 / 06 ### Cloud & DevOps Infrastructure, pipelines and monitoring that let teams release often and safely. - AWS · Azure · GCP - Infrastructure as code - CI/CD pipelines - Containers - Observability - Security & compliance Built around your business ## New software has to work with what’s already there. Very few products start on a blank slate. They need to read from and write to the ERP, the CRM, the billing system and the tools your teams already rely on. Margins engineers around your existing technology environment, so new software removes work instead of adding another system to keep in sync. ### ERP & core systems Build on the operational source of truth. ### CRM & customer platforms Keep customer data consistent across every touchpoint. ### Data infrastructure Design data models and pipelines that stay reliable at scale. ### Internal software Extend or replace proprietary systems without disruption. Production engineering ## Launch day proves it works. Year two proves it was built well. Production software has to survive things demos don’t. A demo asks Production asks Does the feature work? What happens when a dependency fails? Does it load fast here? Is it fast for every user, on every device? Can it store the data? Can we migrate it safely when the model changes? Can it call the API? What happens when that API is slow or down? Can we ship it? Can we ship again tomorrow without breaking it? Does it work today? Can a new engineer change it safely in two years? We make these questions part of the architecture — not problems left for after launch. How we engineer ## From product idea to production software. **Our engineering responsibility doesn’t end at deployment.** Margins can keep running, monitoring and improving the software after launch, or embed engineers with your team through Forward Deployed Engineering. - [Forward Deployed Engineering →](https://margins.agency/services/forward-deployed-engineering) - [Managed AI →](https://margins.agency/services/managed-ai) 1. 01 — Define success — Agree the business outcome, the users and what success looks like. 2. 02 — Architect — Define the data model, integrations, stack and infrastructure. 3. 03 — Validate — Prototype the riskiest flows and test them with real users. 4. 04 — Engineer — Build in short iterations with working software every sprint. 5. 05 — Integrate — Connect it to your systems, data and identity provider. 6. 06 — Launch — Release safely with automated tests, monitoring and rollback. 7. 07 — Iterate — Measure real usage and keep improving from there. Enterprise architecture ## Own the software that makes your business different. You own the code, the data and the infrastructure. We build on mainstream, well-supported technology and document it, so your team or any future partner can run it without us. ### Your cloud Deploy into the customer’s existing cloud environment and technology stack. ### Private infrastructure Build within isolated, customer-controlled environments. ### On-premises Deploy locally where operational, regulatory or data requirements demand it. The objective isn’t to lock your business into a vendor’s platform. It’s to give you software you control. Our technology ## When the software needs AI, it’s already in reach. More and more of the software we build includes AI somewhere — document handling, search, forecasting or automated workflows. Our engineers build both, so AI features can be added without bolting on a second vendor. **Rivermind is our operational layer for enterprise AI.** When a product needs AI in production, Margins uses it for orchestration, integration and operational control.

Software projects lose momentum when product, design and engineering are handed between disconnected teams. Margins keeps those disciplines in one team. 01 ### Product & UX Discovery, research and interfaces people want to use. 02 ### Frontend & Mobile Engineers Web and mobile applications built for speed and accessibility. 03 ### Backend Engineers APIs, services, data models and integrations. 04 ### Cloud & DevOps Engineers Deployment, infrastructure, observability and reliability. 05 ### QA Engineers Automated testing that keeps every release safe. **40+** Skilled professionals **60+** Projects delivered **$100M+** Measured client impact **#11** Deloitte Technology Fast 50 Central Europe Engineering is one part of the journey ## Need more than software? You don’t need to arrive with a technical specification. Margins can start before the solution has been defined and stay after it enters production.
