Backend Engineer | Javascript, Python, RoR, AWS, Node, MongoDB, Stripe

I am a BACKEND ENGINEER with strong experience in building scalable, cloud-based applications using JavaScript, Python, Ruby, AWS, NodeJS, MongoDB, Stripe, Twilio, OpenAI, iElevenLabs and more. Over the past few years, I have led the development of backend systems for web and mobile apps, including a social media platform MVP where I designed and implemented serverless architecture using AWS Lambda, API Gateway, S3, and DynamoDB. This allowed the platform to scale smoothly and stay cost-effective. My core strength lies in designing RESTful APIs, setting up database structures, and writing clean, efficient code that performs well even under high traffic. I regularly work with MongoDB and have a solid understanding of database design, indexing, and query optimization. I also have hands-on experience in authentication systems, role-based access control, and integrating third-party APIs. I enjoy solving complex problems and making backend systems faster, more secure, and easier to maintain. I’m comfortable working independently or with cross-functional teams, and I often collaborate with frontend developers to ensure the entire application works smoothly from end to end. While my main focus is backend, I also have experience with React, which helps me understand how backend and frontend connect. If you're looking for someone who can take ownership of backend development, set up reliable cloud infrastructure, and deliver robust and well-documented APIs — I’d love to help.
