Freelance work and Projects

Here is a project I've worked on, as a freelance gig majorly.

Chatterbugs - Web app to complement physical cards

Developed an end-to-end web application designed to seamlessly complement existing physical card decks sold by the client, enhancing user engagement and product experience.
Enabled secure, user-specific access by integrating a unique 6-digit code linked to each purchased physical deck, unlocking tailored digital content upon verification and payment.
Engineered direct content access through QR codes printed on each physical card, allowing users instant digital navigation to corresponding audio content within the web app.
Led full-stack development lifecycle, including technology stack selection, database architecture, data storage solutions, and infrastructure hosting.
Implemented frontend using Next.js, providing an intuitive, performant, and responsive user interface.
Designed a robust authentication solution with Firebase Authentication, enhanced through custom server-side blocking functions to append additional JWT claims via Firebase Cloud Functions.
Built a secure and scalable backend with PostgreSQL, exposing data through a GraphQL API powered by Hasura. Ensured secure access control by leveraging the custom JWT claims added while authentication.
Developed specialized backend services using Rust with Axum, strategically chosen for superior performance and memory efficiency on resource-constrained environments (hosted effectively on a 1GB RAM DigitalOcean droplet), significantly outperforming alternatives like TypeScript or Python.
Extended server functionalities by implementing Hasura Actions and Event triggers directly within the Rust-based Axum server, enhancing operational efficiency and responsiveness.
Automated deployment pipelines and database migrations using GitHub Actions, streamlining continuous integration and delivery processes for Hasura and Rust services.
