Full Stack Development
I will build browser automation bots and full stack web apps with Python and React
PROJECT DETAILS
Project Description
I help businesses automate repetitive workflows and build full stack web applications using Python, JavaScript, and modern frameworks like FastAPI, Django, React, and Node.js.
With production experience building backend systems that process millions of records across multiple databases, I bring real engineering depth to automation and web development projects, not just surface level scripting.
What I can build for you:
Browser automation and web scraping: I build reliable automation using Playwright, including anti detection techniques and self healing selectors so your automation keeps working even when a target website changes its layout. I have built systems that automate scheduling, messaging, and data collection workflows across multiple platforms at once.
API integrations: I connect and automate workflows across third party platforms including YouTube, Instagram, Facebook, and TikTok, as well as custom REST and GraphQL APIs. If your business needs two systems talking to each other automatically, I can design and build that integration.
Full stack web applications: I build complete applications end to end, from database design through backend APIs to a React frontend. This includes user authentication, role based access control, and secure credential handling using industry standard encryption.
Data pipelines and scraping at scale: I have built ETL and ELT pipelines processing data across multiple databases, and I have built and maintained a leads database platform currently handling over 6 million records with optimized performance for fast search and bulk imports.
AI powered features: I integrate AI into real product features, not just development tools. This includes building AI powered content generation, resume and document scoring against custom criteria, and intelligent workflow automation using large language model APIs.
Why work with me:
I do not just write scripts. I design systems that are secure, reliable, and built to keep working over time. Every automation I build includes proper error handling, rate limiting where needed, and a structure that is easy to maintain and extend later.
I am comfortable working independently and taking full ownership of a project from initial architecture through deployment. I communicate clearly throughout the process and provide updates so you always know where your project stands.
Technologies I work with:
Python, Django, FastAPI, Flask, JavaScript, TypeScript, React, Node.js, Express, PostgreSQL, MongoDB, MySQL, Redis, Docker, Playwright, Celery, REST APIs, GraphQL, Azure
If you need a reliable automation built, a full stack application developed, or an existing workflow streamlined, send me a message with details about your project and I will let you know how I can help.
