My passion is making ideas come to life, be it working solo, as part of a team or leading a team of fellow developers. Throughout my 5 years of development experience, I worked everywhere from startups to big companies, building products from the ground up or implementing new features. Also relevant to my set of skills is that - previously to becoming a developer - I worked as product manager for some of the biggest tech companies in the world, which still helps me to have a more holistic view of the whole work that goes into making a successful product. My go-to technologies are React and Node.js, and I have completed a wide range of projects using them. Those are not the only two libraries/frameworks I'm familiar with though, and I'm always happy to discuss my client's needs and find the best solutions for them. I consider myself creative and hardworking, as my stats show. If you liked my profile so far, drop me a message and we'll discuss how I can be useful to your project.

Want to work with a SERIOUS Shopify Developer capable of understanding your needs as an e-commerce company? Don’t look further! With +5 YEARS of experience in this industry, I had time to understand what e-commerces are looking for: CONVERSION. Here’s what my clients say about me: ✅ ”The most effective freelancer we have hired in the last 5 years” ✅ ”Jeremy is really precise in his work, goes into details to find the right solution for an issue, and even provides several alternatives and previews to make sure you see the full picture.” ✅ ”He is easy to communicate with and definitely loves what he's doing. 5/5 service overall” I always make sure that my clients are 100% satisfied, only after that I could be satisfied myself. We may be a great fit if you are looking for: ➡️ A FULLY CUSTOMIZED website from a Figma/Sketch/PSD design ➡️ Improving your Website Speed ➡️ Implementing a New Feature in your Shopify Theme ➡️ A 100% PERSONALIZED Shopify THEME ➡️ Integration of Shopify Apps ➡️ Fixing bugs and finding a solution for your business Working with me you will: ⭐️ STOP STRUGGLING with developers unexperimented in the E-commerce Industry ⭐️ NOT HAVE to constantly have to follow up to see how the work is progressing ⭐️ Have a daily report on the work done, the problem faced, and the next step for the following day ⭐️ Get a precise plan and realistic estimation of the time needed to accomplish your task ⭐️ Get exactly what you asked for. I know how frustrating it can be to work with a freelancer for days, even weeks, to finally search for another freelancer to correct all the work of the first one. You WON’T HAVE to do that if we work together. Unfortunately, I can’t be the perfect fit for every business - Some of them include: ❌ E-commerce on a different CMS than Shopify (WordPress, Prestashop, Magento, etc..) ❌ Communication is not one of the core values of your company Here is a list of my skills you might be interested in: ⚡️ Front-end development: HTML/XHTML - CSS/SCSS (Tailwindcss) - Javascript (Vanilla, Jquery, Alpine.js, React.js, Next.js, Typescript) - GSAP ⚡️ Back-end development: NodeJs - ExpressJs - Python (Django) - Mongoose - GraphQL ⚡️ Database: MongoDB, PostgreSQL ⚡️ Versioning: Git - Github - GitKraken - GitLense ⚡️ Deployment: Vercel ⚡️ Shopify Specific: SEO Optimization, Speed Improvement, UX Improvement, CRO, Bug Fixes ⚡️ Shopify App Integration & Suggestion (Upsell/Cross-sell, Email Marketing, Langage-Currency-Redirection, Affiliation, Bulk Edit, etc..) ⚡️ Communication: Slack, Discord, Zoom, Google Meet ⚡️ Task Management: Trello, Jira, Notion, Asana I can adapt and learn new skills according to your needs.
