Pol Dotras Roca

Full Stack Developer & DevOps Engineer · Barcelona, Spain

Services

Custom web development (B2C / B2B)

Design and development of websites, landings, e-commerce and internal or inter-company management dashboards.

  • TypeScript
  • React
  • Vue.js
  • Next.js
  • Astro
  • Tailwind CSS
  • Laravel
  • Node.js
  • PostgreSQL

What we deliver

We cover the full cycle, from the frontend to the API and the database, delivering the product ready for production. Optionally including deployment, CI/CD and separate dev/prod environments from day one. Everything bundled in a single service, so you don't need to coordinate multiple profiles or vendors.

Custom software and microservices

Development of brand-new applications from scratch or extension of existing ones via custom code or standalone microservices that integrate without altering the current system's core.

  • PHP
  • Python
  • Java
  • Kotlin
  • C#
  • Node.js
  • Docker
  • REST

Our approach

We apply development best practices and separation of concerns adapted to the size and context of each project. The result is maintainable, testable code ready to grow: adding new modules or swapping parts in the future does not require rewriting the system.

ERP: modules, automation and integrations

New module development for existing ERPs, internal process automation (invoicing, stock, reporting, syncs) and integration between ERPs or with external platforms (CRMs, marketplaces, payment gateways, partner systems).

  • C#
  • .NET
  • SQL Server
  • REST
  • Webhooks
  • Cron

What sets us apart

Our experience includes building an ERP and working with multiple ERPs along the way. That means we don't tackle each task in isolation: we understand the real business needs and how every automation should fit within the operational flow.

Cloud, DevOps and CI/CD

Application migration to AWS, Azure or Google Cloud. CI/CD pipelines with GitHub Actions. Infrastructure as code with Terraform. Containerization with Docker and orchestration with ECS or Kubernetes.

  • AWS
  • ECS
  • S3
  • Terraform
  • Docker
  • GitHub Actions
  • CI/CD
  • Cloudflare

What we deliver

The cloud is more than virtual machines and file storage. We design architectures that leverage every service needed to get an infrastructure optimized both technically and economically, plus auto-scaling on demand. You pay for what you consume, not for what you keep running.

AI automations and advanced integrations

OCR pipelines for massive document digitization. Virtual assistants and AI receptionists integrated with telephony. Conversational enterprise bots (WhatsApp, web). Integrations with model APIs (Bedrock, Anthropic, OpenAI).

  • AWS Bedrock
  • Amazon Connect
  • Azure AI Documents
  • Anthropic
  • OpenAI
  • Python
  • OCR

What we deliver

We automate the repetitive, low-value tasks that drain your team's time so people can focus on what really matters: judgment, decisions and skilled work. The result is a more productive team and processes that scale without needing to grow headcount.

Data migration and refactoring

Data migration across platforms, formats or databases, including transformation, validation and schema refactoring when needed.

  • SQL Server
  • PostgreSQL
  • MySQL
  • Python
  • ETL
  • Validation

Our approach

We treat migrations as our own. We meticulously analyze every field, property and value to guarantee a migration with the best possible format without losing any data or property.

Enterprise SSO and 2FA integrations

Single Sign-On (SAML, OpenID Connect, OAuth2) and second-factor authentication (TOTP) integration in existing applications, with direct coordination with the end client's IT team when federation between organizations is involved.

  • SAML
  • OpenID Connect
  • OAuth2
  • JWT
  • 2FA TOTP
  • Active Directory
  • Federated AD

What sets us apart

It's a feature where the fear of breaking authentication holds many teams back, and rightly so — it carries a lot of responsibility. Thanks to our experience with these integrations, careful work and rigorous prior analysis and research, we guarantee a clean integration with no service interruptions and no impact on the authentication of other dependencies or services that rely on it.

Custom MCP servers

Development of MCP (Model Context Protocol) servers that connect your internal systems (ERP, CRM, databases, your own APIs, management tools) with AI assistants such as Claude, ChatGPT or Gemini.

  • MCP
  • TypeScript
  • Node.js
  • Anthropic
  • OpenAI
  • Bedrock

What we deliver

Your team will be able to ask an assistant to check stock, generate reports, update records or kick off processes talking directly to your systems, without relying on the model's training knowledge or outdated data.

Helpdesk and SysAdmin services

Technical support and systems administration. Server maintenance, user and domain management, workstation, POS and back-office setup, incident resolution and first- and second-level support.

  • Active Directory
  • DNS
  • SSL
  • Bash
  • Linux
  • Windows Server

What we deliver

The natural complement to the rest of the services. If we build your software, your cloud infrastructure or your automations, we can also keep them running. A single point of contact for everything related to your technology, without having to re-explain the context every time something breaks.

Custom scripts for FiveM

Development of scripts and custom resources for FiveM roleplay servers. Game mechanics, economy systems, framework integrations (ESX, QBCore), admin panels, custom commands and connection to databases or external services.

  • Lua
  • JavaScript
  • ESX
  • QBCore
  • MySQL

What sets us apart

We know the ecosystem from the inside. We have experience building successful servers and we know what makes a server actually work.
