Full Stack Developer for the BIOST3 research group (Clinical Statistics, Data Science, and Bioinformatics). Specialized in architecting and building complex, highly scalable web platforms end-to-end. Proven experience constructing robust systems with Next.js, Python, and PostgreSQL, integrating advanced AI models (like RAG architectures), and managing the complete software lifecycle through full service dockerization and CI/CD automation.

Part-timeMay 2025 - Present
  • Architected and developed full-stack web platforms using Next.js and Python.
  • Implemented a RAG system for processing and linking data with scientific literature.
  • Led frontend development and engineered backend document chunking and ranking systems, improving information retrieval.
  • Migrated a video processing application from a local environment to a scalable AWS cloud architecture, leveraging EC2 instances (g4dn.xlarge with CUDA) for AI model execution.
  • Automated cloud processing workflows and deployments by configuring custom AMIs, orchestrated through AWS Lambda, S3, and IAM roles.
  • Implemented CI/CD pipelines with GitLab CI and Docker Compose for automated multi-application VPS server deployments.
  • Presented and defended software architectures and final products in strategic meetings with prestigious institutions and companies (SequentiaBiotech, VHIO, Harvard University, etc.), adapting technical communication for cross-functional teams.

InternshipDec 2024 - May 2025
  • Completely overhauled the architecture of a legacy desktop application (PyInstaller), drastically improving codebase maintainability in Python.
  • Developed a new native graphical user interface using PyQt5, creating a dynamic pipeline adaptable to varying user requirements.
  • Implemented interactive data visualizations with Matplotlib and Pandas for the analysis and extraction of complex physical parameters (viscoelasticity).
  • Integrated and optimized advanced Computer Vision models (SAM2 and CoTracker) to increase accuracy within the video tracking and analysis pipeline.
