About Yunior César

I am a Scientific Software Engineer specialized in building web tools for research, data-processing workflows and technical teams.

I help research groups, biotech companies and engineering teams turn scripts, pipelines and analysis outputs into usable web applications: dashboards, metadata browsers, internal APIs, workflow launchers, task monitoring interfaces and automated reporting tools.

My main stack includes Python, FastAPI, Celery, Redis, React, TypeScript, PostgreSQL and Docker. I can work across the full stack, from backend architecture and background task execution to clean user interfaces and data visualization.

I am especially useful in projects where the challenge is not only to build a web app, but also to understand complex workflows, scientific data, metadata, images, logs, processing steps and user-facing result exploration.

Typical projects I can help with:
- Scientific dashboards and internal tools
- Python pipeline to web application/API
- Metadata and result viewers
- Workflow monitoring, logs and reporting
- FastAPI backend development
- React/TypeScript frontend development
- Data visualization and exploration tools
- Docker-based deployment and technical documentation

I like working on practical, well-scoped projects where software can make complex technical processes easier to use, monitor and understand.
