Current Tech Stack

We are fully cloud-native, leveraging AWS and adopting a Lean, API-first product development approach driven by modern cloud technologies and thoughtful design practices.

Our backend applications are built using Python, FastAPI, Pydantic, and SQLAlchemy (MySQL). On the front end, we predominantly develop with Angular and also utilize Headless Wagtail and WordPress for select products. To ensure code quality and a consistent release pipeline, we employ GitHub Actions for CI/CD along with tools like Renovate, ruff, Poetry, and pre-commit.

We containerize our applications using Docker and Docker Compose. Currently, we are transitioning from AWS Lambda-based deployments to Kubernetes-managed services, and moving from AWS CloudFormation to Terraform for infrastructure as code. We continue to expand our capabilities in knowledge graphs (Neo4j) and database technologies (MySQL, DynamoDB).

Additionally, we are innovating in the healthcare domain through human-in-the-loop Machine Learning, including the development of LLM-based solutions and other AI techniques.
