✅ Top Rated FullStack expert Why Work With Me? 🔹 Top-Rated Focus: I dedicate 100% attention to one project at a time, ensuring quality, timely delivery, and clear communication. 🔹 10+ Years of Impact: Built apps serving 1M+ users, optimized performance by 70% for Fortune 500 companies, and led cross-functional teams. 🔹 Client-Centric Approach: I translate ideas into intuitive, scalable solutions—whether it’s a startup MVP or enterprise-level system. I build the backend infrastructure that AI products run on. Over the past 12 years I have shipped production systems across fintech, insurtech, energy, and AI — from a mobile app with 500K+ downloads in Southeast Asia to a custom RAG pipeline currently running in production at a Stockholm-based AI startup where I serve as Lead Developer. My core work right now sits at the intersection of cloud infrastructure and AI systems — specifically FastAPI backends, custom retrieval-augmented generation pipelines, AWS architecture, and Kubernetes. I have built RAG systems both with LangChain and completely from scratch without any framework, depending on what the project actually needs. On the infrastructure side I work across the full AWS stack — ECS, Lambda, RDS, VPC, IAM, CloudFront — and I am currently leading a Kubernetes migration with zero-downtime deployment strategy at my company. What I do not do is take on five projects at once and disappear. I work with one or two clients at a time, communicate daily, and treat your codebase like my own. If you are building an AI product, a data-intensive backend, or need someone to take ownership of your cloud infrastructure — I am straightforward to work with and I know this stack deeply.

I am a Senior Web Developer with over 19 years of experience in creating highly custom Magento websites. As a result, I have become an expert in Magento Commerce (Enterprise), Commerce Cloud, and Open Source (Community). I have customized nearly every aspect of Magento and debugged some of it's deepest layers to determine how to implement the one line of code that solves the root issue rather than the 100 lines of code that treat the symptom. I have also completed several Magento 1 to Magento 2 upgrades. My primary strengths are in understanding business requirements, writing solid code that solves the right problem and driving results for my clients. I also have experience in rapid prototyping to create quick low-cost solutions that can be tested. If it's determined that the solution gets the results that my client wants, I can expand on the solution so that it's solid. This way if the solution doesn't get the results my clients want, it can be found out before a large amount of money is spent. A Few Recent Projects The Packaging Group: Created a Magento Commerce Cloud website that provides bulk product pricing for both B2B and B2C customers. Developed a complex grid system to allow displaying large numbers of products with different product attributes in a way that is compelling for customers. Connected with Akeneo's PIM solution and customized the integration to allow seamless product syncing that also updated things that aren't typically integrated like custom UOMs. Dozens of other customizations, but those mentioned are the major pieces. Invisible Fence Brand: Built the Invisible Fence site from scratch and connected it with Invisible Fence's internal custom ERP system. This site includes a lot of complexity as they have nearly 300 dealers, which are each tied to one of 12 distributors. Each dealer can have their own website, online store, pricing, promotions, products, payment gateways, schedulers, content management system, etc. Created a portal for dealers, so they could manage both their subdomain sites as well as their dealer stores. Set up dozens of goal trackers to help them optimize conversion rate as the site generates nearly all of their new customer acquisition across all dealers. PetSafe & SportDOG: Created an integration between the Magento and Oracle E-Business Suite's ERP. This included syncing customers, orders, payments, shipments, etc. so that an order in one system exactly mirrored the orders in the other system regardless of whether the order was placed in Magento or by the Customer Service department in Oracle. Created a custom subscription system that processed orders through both systems. Head Covers: Helped to upgrade them from Magento 1 to Magento 2. Completed upgrade and handle continuous site maintenance. For example, I helped them to fix a bug in Magento core related to massive numbers of custom options on pages, their site was loading some product pages in 35s or more. Resolved several issues like this. Texas Precious Metals: Texas Precious Metals needed help building a solution for orders that were greater than $10K so they could take direct payment instead of paying high credit card fees. I built a custom integration with Dwolla to allow customers to create a profile, connect their banking accounts, verify microtransactions to confirm their banking accounts, and ultimately use this payment method during checkout. In addition they have a unique offering due to their sale of precious metals where the price changes constantly and the average order value is high. Built a solution that updates pricing every minute but allows a customer to "lock in" pricing for 10 minutes once they add to cart. Created a fully custom checkout solution that includes a price timer, custom shipping to multiple depositories (Cayman Islands, etc), custom pricing discounts if the customer doesn't choose credit card payment, down payment for non-credit card payments (e.g. cash, check, etc), and several other modifications.
