Custom Flask Solutions: Flexible, Fast, & Scalable Web Apps
Need a bespoke web solution without the bloat of heavy frameworks? I specialize in building custom applications and microservices using Flask. From rapid MVPs to specialized REST APIs, I deliver clean, modular Python code designed for stability and growth.
Why Choose This Project?
I don't just write scripts; I build architectures. My Flask projects focus on:
Total Flexibility: I build exactly what your business requires—ensuring a lightweight and high-speed application.
Modular Design: I use a "Blueprint" structure, meaning your app stays organized and easy to scale as you add features.
Pro Security: Secure implementation of JWT/Session authentication, password hashing, and protection against CSRF and SQLi.
Database Expertise: Robust integration with PostgreSQL, MySQL, or SQLite using SQLAlchemy for reliable data management.
DevOps Ready: Every project is fully Dockerized, making deployment to AWS, DigitalOcean, or Heroku seamless.
I strictly follow PEP 8 standards to ensure your codebase is professional and maintainable. Let’s turn your vision into a production-ready application.

Python or PHP developer with API and AWS Lambda - MUST WORK EST WORK HOURS!
Terrible communication, you don't know when he is working or when he is not working. I'm pretty sure I was overcharged and didn't catch it in-time. Didn't stick to the specifications as he only built a database and I had to tell him to go back and actually create the api connection, poor code definitely wouldn't hire for anything.

Steps for completing your project
After purchasing the project, send requirements so Raj can start the project.
Delivery time starts when Raj receives requirements from you.
Raj works on your project following the steps below.
Revisions may occur after the delivery date.
Architecture & Logic Mapping
We start by defining your app's structure. I will map out the database schema, core business logic, and specific Flask Blueprints to ensure the application is modular, organized, and easy to scale from day one.
Environment Setup & Backend Development
I’ll configure the Flask environment, initialize the database (SQLAlchemy), and build the core functionality. This includes setting up secure authentication, RESTful routes, and any complex background logic required for your project.
