## Services

Each service has its own page: typical needs, what you receive, how the work runs, technologies and questions.

- [Custom software & SaaS](https://www.deusengineering.com/en/services/custom-software-saas): Internal platforms, client portals and multi-tenant SaaS products, designed around the workflow and data you actually have.
- [Product & UX/UI design](https://www.deusengineering.com/en/services/product-ux-ui-design): Product definition, user flows and interface design for web applications — drafted in code with realistic data, so development starts from the screens you approved.
- [React, Next.js & TypeScript front ends](https://www.deusengineering.com/en/services/react-nextjs-frontend): Fast, accessible application interfaces in React and Next.js with strict TypeScript — rendered on the server where it matters, typed against the API behind them.
- [Websites & technical SEO](https://www.deusengineering.com/en/services/websites-technical-seo): Company and product websites in Next.js or prerendered React, with the technical SEO built into the code, so search engines and AI assistants can read them correctly.
- [APIs, backend architecture & PostgreSQL](https://www.deusengineering.com/en/services/api-backend-postgresql): Data models, APIs and server-side logic that keep business rules in one place — with PostgreSQL doing the work it is good at.
- [Applied AI & business automation](https://www.deusengineering.com/en/services/applied-ai-automation): Language models and automation inside defined workflows — drafting, checking, extracting and routing — with a person approving what matters.
- [ML & AI R&D prototypes](https://www.deusengineering.com/en/services/ml-ai-prototypes): Prototypes and experiments that test whether a machine learning or reinforcement learning idea works — in simulation or on offline data, with results you can rerun.
- [Cloud infrastructure & integrations](https://www.deusengineering.com/en/services/cloud-infrastructure-integrations): Deployments, CI/CD, email, storage and third-party APIs wired together so releases are routine and integrations fail loudly, not silently.
- [Security-aware architecture](https://www.deusengineering.com/en/services/security-architecture): Access control, data isolation and secure defaults designed into the architecture — in the data model, the file storage and the server, not added after launch.
- [Technical audit & architecture consulting](https://www.deusengineering.com/en/services/technical-audit-consulting): A written review of a system you run or a decision ahead — architecture, data model, code, dependencies, security and operations — with findings in priority order.
- [Software modernisation & maintenance](https://www.deusengineering.com/en/services/software-modernisation-maintenance): Taking over and maintaining software you already run — framework, dependency and database upgrades done step by step, while the system stays in use.
- [Remote engineering partnership (B2B)](https://www.deusengineering.com/en/services/remote-engineering-partnership): Full-stack engineering capacity for your product under a B2B contract with a registered Serbian company — in your repositories and your working hours.

## Selected work

- [Pametni Advokat](https://www.deusengineering.com/en/work/pametni-advokat): A production web platform for Serbian law offices: cases, clients, hearings and deadlines, private documents, fees under the bar tariff and invoicing in one system — with an AI assistant that prepares and checks while the lawyer decides. Status: In production at pametniadvokat.rs. DEUS Engineering’s own product — defined, designed, engineered and maintained in-house. Product site: https://www.pametniadvokat.rs
- [Ariaska RL](https://www.deusengineering.com/en/work/ariaska-rl): An experimental research platform by founder Filip Volf: five agents with distinct roles learn through reinforcement learning in isolated, simulated environments, with a language model as an optional mentor that can be switched off. Status: Experimental · core recovery merged 17 Oct 2026 · partial research readiness. The founder’s research project, published as source-available under a non-commercial licence. Not a DEUS client product. Repository: https://github.com/Reckless98/Ariaska_RL. It is research in simulated environments, not a production system.
