On the...I’m a Full Stack Web Developer with 4+ years of hands-on experience building scalable, production-ready web applications from scratch and improving existing systems. My core strength is JavaScript and TypeScript, and I work comfortably across both frontend and backend, delivering complete end-to-end solutions. On the backend, I mainly work with Node.js and Nest.js, building clean, structured APIs using REST and sometimes GraphQL. I focus a lot on writing maintainable code, structuring business logic properly, and making sure the system can scale without turning into a mess later. I’ve also worked with Express when lightweight setups were needed. On the frontend, I build modern, responsive interfaces using React and Angular. With React, I’ve worked with Redux, Saga, and other state management tools, and on Angular projects I’ve used RxJS, NgRx, and Angular Material. I care about performance, clean UI structure, and making sure everything feels smooth for the end user. For databases, I’ve worked with MongoDB, PostgreSQL, and MySQL, handling everything from schema design to query optimization and maintenance. I understand how to structure data depending on the business case, whether it’s relational or NoSQL. I also have solid experience working with cloud platforms, mainly AWS (Lambda, EC2, S3, RDS), and some exposure to Google Cloud and Azure. I’ve handled deployments, basic DevOps tasks, and setting up environments for production systems. Integration work is another strong area for me — I’ve built and maintained integrations with third-party services like Stripe, Google APIs, Facebook, Salesforce, and others. I understand how to deal with external APIs, authentication flows, and edge cases that usually come with them. Beyond coding, I pay attention to communication and understanding the business side. I try to not just implement features, but actually understand what problem we’re solving and suggest better approaches when needed. I’m used to working independently as a freelancer, managing tasks, and delivering results on time. I’ve worked on different types of projects including SaaS platforms, CMS systems, eCommerce (Shopify, WordPress), and custom business tools. I’m comfortable jumping into existing codebases, fixing issues, refactoring, or building new features from scratch. If you’re looking for someone who can take ownership, write clean code, and consistently deliver solid results without overcomplicating things — I’m ready to help. less -
