# Doers DF

> Doers DF is a software engineering partner for product organizations. We integrate senior engineering teams — dedicated teams, team extension and end-to-end product delivery — into enterprises, software companies and international organizations that need to increase delivery capacity without lowering their quality, security or architectural standards.

Doers DF is an independent software engineering company based in Madrid, Spain, building enterprise software since 2002. We are ISO 9001 and ISO 27001 certified, EU-based, and we work as a long-term engineering partner rather than a project vendor: our teams operate inside the client's roadmap, with our own delivery discipline and accountability.

Organizations typically bring us in for one of three reasons: their roadmap is larger than the team that has to deliver it (capacity), the work sits outside their current expertise — legacy platforms, AI systems, complex integrations — (complexity), or a critical platform needs an engineering team accountable for it over years, not a project team that hands over documentation and leaves (continuity).

## How we engage

- Dedicated Engineering Teams — a complete, cross-functional team that operates as a unit inside your organization. We handle recruitment, retention, technical leadership and continuity; you hold the priorities.
- Team Extension — senior engineers embedded in your existing teams, under your process and your definition of done. EU-based, full working-day overlap with European teams.
- End-to-End Product Delivery — full ownership of scope, delivery and outcome, from discovery to production and run. We stay after launch: we are structured to operate and evolve what we build.
- Technology Consulting & Discovery — architecture reviews, technical due diligence and delivery roadmaps. Short, senior, time-boxed engagements whose deliverable is a decision document, not a sales proposal.

## What we build

- Product Engineering — frontend, backend, mobile, APIs, QA and test automation, performance and security engineering.
- AI & Intelligent Automation — enterprise RAG, AI agents, copilots, intelligent document processing, LLM integration, evaluation and observability, MCP integrations.
- Enterprise Platforms & Modernization — legacy modernization, enterprise and headless CMS, commerce and B2B platforms, systems integration, data engineering, multi-market platforms, long-term maintenance.
- Experience Design — UX research, UI design, design systems, WCAG accessibility, prototyping, high-performance interactive and 3D experiences (WebGL, Three.js).
- Cloud & DevOps — AWS, Docker, Kubernetes, CI/CD, observability, site reliability.

## Certifications

Doers DF operates under internationally recognized, externally audited standards:

- ISO 9001 — Quality Management
- ISO 27001 — Information Security Management

Every engagement runs under these controls regardless of team size. Client code, credentials and data are handled inside a certified system, in the EU, under GDPR.

## Why organizations choose Doers DF

- IP belongs to the client from the moment the code is written
- Exit readiness from day one: documentation and infrastructure-as-code maintained throughout, with a supported transition if the client takes the system in-house

- Systems still in production after a decade or more
