I have designed and built 86+ web apps and websites in my career for satisfied clients and businesses, as a senior solutions architect and software developer with over 12 years of experience. I focus on 2 things only when building solutions: 1. Saving costs by optimizing wherever I can to offer the most cost-efficient solutions 2. Focus on user needs and only building out features that are needed with lean methodologies I have deep experience in product design, frontend and backend development, cloud development, serverless and MVP design. My 2 biggest recent accomplishments: - I built a business onboarding application that was able to support over 40K users per month, making it scalable, performant and fast - I built an invoicing app for a startup that had a stellar UI and UX based on their needs and was able to scale it seamlessly. My Tech Stack: - React JS - AWS (DynamoDB, Lambda, EC2, S3, API Gateway, etc) - Next JS - Node JS - JavaScript - MongoDB - Firebase - Java - Python - SQL - NoSQL - React Native
