Senior Python Backend Engineer | GenAI & AWS Cloud Solutions Architect
About Me
I am a senior software engineer and cloud solutions architect with more than 14 years of experience building backend systems, microservices, and production-grade APIs. My work has focused heavily on Python, AWS, and scalable architecture, with a strong emphasis on clean code, testing, and reliability.
I have designed and deployed event-driven and serverless solutions, including REST APIs and microservices that support high-demand business operations. I enjoy turning complex technical requirements into stable, maintainable products that perform well in production environments.
In recent roles, I have applied generative AI to real business problems. I engineered a Google Gemini-powered AI agent that achieved 100% structured data extraction and automated 90% of a critical approval workflow, significantly reducing manual effort and turnaround time.
My background also includes experience in banking, travel, real estate, invoicing, accounting, and internal business systems. I have worked across Python, .NET, SQL Server, PostgreSQL, Oracle, FastAPI, Flask, and AWS services, adapting quickly to different stacks and business domains.
I am highly autonomous and comfortable leading technical initiatives, documenting best practices, and helping teams adopt new tools and workflows. I value collaboration, but I am equally effective working independently on complex backend and cloud challenges.
I am based in Bogotá, Colombia, and I communicate professionally in Spanish and English. I am looking for opportunities where I can continue building intelligent, scalable backend solutions and contribute to impactful software products.
