Teztamam - Infrastructure Modernization & Full-Stack Development

Revamping the OTP authentication flow for the Teztamam web app, developing a custom Python-based Google Form microservice, migrating the .NET 6 main project to Contabo VPS with an Nginx reverse proxy, and establishing CI/CD pipelines.

Project Overview

The Teztamam project was comprehensively restructured end-to-end to modernize the system's performance, security, and deployment processes. By improving backend services and integrating DevOps practices (Docker, CI/CD, Reverse Proxy), the application's scalability and stability were maximized.

🛠️ Key Improvements

1. Authentication and Security Infrastructure

The existing login and signup logic was completely overhauled.
To enhance user security, the OTP (One-Time Password) authentication flow was redesigned from scratch and cleared of critical bugs.

2. Custom Microservice Development with Python

A Google Form Parser was built from the ground up using Python to ensure seamless integration with external data sources.
This service was isolated using Docker and deployed on the Google Cloud Platform (GCP).
A CI/CD pipeline was established to automate the deployment processes of the service.

3. Server and Deployment Architecture (DevOps)

The hosting infrastructure for the main project (developed with .NET 6) and the database was migrated to a Contabo VPS environment.
An Nginx server was configured to establish a Reverse Proxy architecture. This securely and optimally routed incoming traffic to the main project and the database.

4. User Interface (UI) Optimizations

Alongside robust backend architectural changes, visual and functional improvements were made to the user interface (UI) to elevate the overall user experience.
