About Traian
Does your business rely on fragile backend processes, or do you need a highly scalable platform built by an engineer who doesn't need to be micromanaged ?
I am a Senior Software Engineer specializing in enterprise cloud architecture, backend process automation, and full-stack development. By day, I am the sole architect managing a 3-service Azure platform that processes over 2.2 million transactions for 17,000 enterprise users. I bring that exact same level of reliability, speed, and architectural rigor to your startup or scaling business.
1. Full-Stack Product: Building responsive, role-based web applications (React, Node.js, TypeScript).
2. Cloud Backend: Architecting decoupled, event-driven pipelines (Azure Functions, Storage Queues) to automate legacy manual tasks.
3. Data Integration: Engineering high-volume data syncing (BigQuery to Azure SQL) and integrating deeply into the Microsoft 365 ecosystem (Graph API, Entra ID SSO).
⚡ How I can help your team:
• Architecting and building REST APIs (Node.js/Express/.NET) with idempotent logic.
• Modernizing fragile workflows (like Power Automate) into robust Azure queue-based pipelines.
• Integrating custom enterprise applications into Microsoft Teams and SharePoint.
• Providing Senior-level code review, CI/CD configuration (Azure DevOps), and architectural planning.
I write clean, documented code and build systems that don't crash. I am based in Barcelona (CET) and am available for fractional engagements to help you scale your technology without the overhead of a full-time hire.
