Description

Senior full-stack architect with 20+ years designing complex ERPs and CRMs for industry.

End-to-end development of SaaS solutions: analysis, architecture, code, Azure deployment, and support.

Seekinghighly complexprojects where I can be the sole technical-business interface.

Specialist in demanding business logic, ERP/CRM integrations, and optimized performance.

**Primarily Microsoft stack**: .NET Core/10, C#, Blazor, WPF, Azure, CosmosDB, Entity Framework, etc., although I use modern front-end frameworks if the project requires it (Angular/Vue).

Computer engineer with extensive experience designing and developing custom high-complexity solutions for SMEs and industrial companies. Over the last 10 years, I have designed, developed, and operated several key business applications: advanced CRMs with complex offers in multiple currencies and languages, multi-tenant SaaS platforms on Azure, internal applications connected to external ERPs and CRMs, and a complete custom ERP for a group of three companies with very specific processes. Also integration with **VeriFactu**.

In most projects, I simultaneously act as software architect, functional analyst, senior full-stack developer, and deployment manager, taking on the complete lifecycle: from user analysis to production deployment and ongoing support.

My natural domain is projects that are “difficult to fit into a standard product”: complex business logic, flexible rules, demanding data models, integrations with existing systems, and high requirements for quality, robustness, and performance.

Currently exploring AI: Integrating LLMs into real workflows to automate repetitive processes without sacrificing control.

I am looking for projects where I can provide high value: solid architecture, clean and maintainable code, and a very direct relationship with the business to turn vague requirements into software that is actually used.
