Acerca de Aleix
Freelance Backend & Integration Engineer based in Barcelona, available for remote EU contracts.
Current stack from strongest specialization → secondary: .NET / WinForms · SQL Server · Scripting (PowerShell, VB) · Integration & Orchestration (ActiveMQ, Apache Camel, JavaSpring Boot) · Python · Power Platform · Dynamics 365 CE
I specialise in enterprise production systems, working mainly with .NET / WinForms, SQL Server, and integration & orchestration using ActiveMQ and Java Spring Boot + Apache Camel. I’m most effective in environments where reliability, automation, and performance really matter.
What I bring to projects:
- Creation, maintenance and evolution of .NET / WinForms applications: bug fixing, new features, refactoring, and production stability.
- SQL Server: stored procedures, schema changes, execution state modelling, and data flow design.
- Integration & orchestration: ActiveMQ with worker/orchestrator patterns, improving robustness and execution flows.
- Performance optimisation: improved a Java Spring Boot + Apache Camel middleware by introducing parallelism, reducing execution time from ~24h to ~9h (≈62% faster).
- Automation & tooling: custom C# tools built from scratch (multi-threaded folder watcher with email alerts, XML log analyser with alerts), scripting improvements (VB / PowerShell), and process automation with Power Automate.
Available for short to mid-term contracts (3–6 months). Happy to discuss how I can support your project. You can check my portfolio in aperezvidal.dev
