Professional profile
Systems Engineering student and Junior Software Developer with practical experience building software from idea to production: architecture decisions, backend implementation, secure integrations, and delivery. I have worked on microservices with hexagonal/clean architecture, deterministic build pipelines, ETL/data workflows, and web products with Next.js + TypeScript. My background in technical support strengthened incident resolution, KPI ownership, and communication with technical and non-technical stakeholders.

Software Developer (Project-Based)
EduSinapsis | Remote
Jan 2026 - Present
Designed and implemented ai-assets-api in a microservices monorepo using Hexagonal/Clean Architecture (application, domain, infrastructure). Built use cases with Repository and Dependency Injection patterns, versioned asset flows (`v000N`), and rollback-safe persistence. Implemented a deterministic build pipeline (esbuild + Tailwind) for AI-generated ZIP assets with strict validations (path traversal, blocked files, allowed extensions), CSP injection, and secure bridge communication (`postMessage`) for sandboxed iframe execution. Integrated GCS/local storage adapters, MongoDB metadata, and gateway access patterns.
