I am a backend engineer with 9+ years of experience building and improving complex systems. Throughout my career, I have focused on understanding messy codebases end to end, reducing technical debt, and introducing stronger engineering practices that make products more maintainable and scalable.
I am comfortable working across both backend and frontend when needed, and I have spent much of my career in .NET, ASP.NET Core, SQL Server, PostgreSQL, Redis, and Angular. I also have experience with Python, Flask, React, Hono, Supabase, Docker, and Cloudflare Workers, along with identity and SSO integrations such as Okta, Cognito, Google Identity, SAML, and OAuth.
In my recent roles, I have taken ownership of production systems, led architecture decisions, and delivered improvements that had measurable impact. I have reduced load times on data-heavy modules, introduced repository pattern and DDD-based structures, built testing strategies from scratch, and helped teams modernize legacy systems without disrupting operations.
I have also worked closely with domain experts to translate business workflows into reliable software behavior. In one role, I reverse-engineered undocumented SSO flows and created technical specifications that became the reference standard for the engineering team. In another, I co-founded a clinical workflow platform and owned technical decisions from stack selection through deployment strategy.
My background includes full-stack development for enterprise logistics tools, speech-to-text document generation platforms, aviation operations systems, and IoT-connected enterprise APIs. I have repeatedly been trusted to stabilize systems, improve code quality, and deliver maintainable solutions in remote and contract environments.
I am based in Guadalajara, Mexico, and I speak Spanish natively, English professionally, and Korean at a basic level. I am looking for opportunities where I can continue building robust backend and full-stack systems, modernizing legacy platforms, and contributing strong engineering leadership.
Co-founded a clinical workflow platform from scratch, owning technical decisions from stack selection and schema design to deployment strategy. Worked directly with domain experts to translate clinical workflows into structured system behavior. Chose Supabase for rapid MVP delivery, then migrated business logic into a dedicated Hono API layer on Cloudflare Workers as the product grew.
Reverse-engineered undocumented SSO integration flows across Okta, Amazon Cognito, and Google Identity. Produced technical specifications adopted as the reference standard for a 10-person engineering team and owned the migration into a DDD-based architecture.
Served as sole technical owner of a large production platform. Reduced module load times by over 50%, introduced repository pattern and SOLID principles, built test coverage from scratch, designed a 4-environment deployment pipeline, built a Hangfire-based notification system, and led the Angular 11 to 17+ upgrade.
Extended the document processing pipeline to support new document types and custom output configurations. Refactored messy modules into maintainable code and helped resolve production instability caused by dependency injection misconfiguration.
Built internal operational tools for logistics and parking management workflows using React and Node.js REST APIs. Diagnosed and fixed defects in a parallel .NET legacy system and contributed to a frontend migration to Vue and Tailwind CSS.
Built and maintained REST APIs consumed by IoT devices and led the migration from .NET Framework to .NET Core while coordinating with junior team members and dependent systems.
Contributed to internal development tooling.
Contributed to enterprise-scale global web platforms.
