🏢 Contenda 2022-04 - 2024-04

Engineering Lead leading Contenda's engineering efforts building out both our platform and our team

Led the company's engineering efforts with a holistic approach, working in parallel on both the team and its output: improving overall architectural and code quality decisions, holding regular engineering 1-1 meetings with other engineers, introducing better logging / monitoring capabilities, improving our documentation and more.

Architected a scalable media processing and ML pipeline on AWS, using Batch, Lambda, RDS, S3, DynamoDB and other services; including some early spike versions and experiments with other AWS technologies to work around current limitations of AWS offerings.

Implemented significant parts of our backend stack in python, using a SQLModel, Alembic, FastAPI stack, and worked on the integration of various LLMs, e.g. GPT and Claude.

Collaborated with 3rd party DevOps contractors to help our small team realize its vision, patching out holes in our overall experience with the required technologies.

Spearheaded building out our authentication stack, from the start of choosing a provider to the end of finishing the integration. A process more complicated than usual, as our stack had to support both 1st and 3rd party clients with API access.
