Hire the Best JavaScript Developers

If your Shopify, HubSpot CMS, or WordPress site is slow, hard to update, buggy, or too dependent on developers, I can help you fix the real problem without adding more technical mess. I work with agencies, ecommerce brands, and marketing teams that need reliable development beyond basic content edits: clean implementation, troubleshooting, performance improvements, reusable modules, flexible templates, and CMS/ecommerce structures their team can actually manage. I bring 13+ years of hands-on web development experience and 8,800+ hours on Upwork across Shopify, HubSpot CMS, WordPress, and WooCommerce projects for US-based agencies and ecommerce brands. Common projects I can help with: - Shopify theme improvements, custom sections, templates, product page updates, metafields/metaobjects, and product-related functionality - HubSpot CMS modules, HubL/HubDB components, landing pages, blog/resource templates, and dynamic front-end builds - WordPress and WooCommerce fixes, custom implementation, reusable content components, and theme/plugin adjustments - Performance improvements, Core Web Vitals cleanup, image/media optimization, and front-end technical fixes - Technical SEO implementation across templates, content structure, metadata, schema, and internal linking support - Debugging complex layout, responsive, UI, JavaScript, Liquid, HubL, PHP, and CSS issues - Ongoing support for launches, site updates, production fixes, and improvements inside existing codebases I’m used to working inside active client projects, existing codebases, and fast-moving environments where quality, clarity, and reliability matter. I can jump into a project, identify what needs to be fixed or improved, and move it forward efficiently. I also use AI-assisted workflows where appropriate to speed up research, troubleshooting, and implementation, while keeping quality control and technical decisions grounded in hands-on development experience. If you’re looking for a developer who can contribute quickly and solve real technical problems across Shopify, HubSpot, and WordPress, let’s talk.

I am a FULL STACK ENGINEER with strong experience in building scalable, cloud-based applications using ReactJs, NextJs, JavaScript, Python, Ruby, AWS, NodeJS, NestJS, MongoDB, Stripe, Twilio, OpenAI, iElevenLabs and more. Over the past few years, I have led the development of froentend & 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 the end to end development, set up reliable cloud infrastructure, and deliver robust and well-documented APIs — I’d love to help.
