Adil M.

Ruby on Rails, Shopify and full stack development, from the database through to the storefront. I work US business hours, which means questions get answered the same day instead of waiting on a timezone gap. ✦ FULL STACK DEVELOPMENT 🔹 Build new products from scratch 🔹 Ruby on Rails, React, Next.js, JavaScript 🔹 PostgreSQL, Redis, background jobs and queues 🔹 REST APIs and third-party integrations 🔹 Performance tuning and production debugging 🔹 SaaS, ecommerce, internal tools and dashboards 🔹 Legacy codebase improvements and upgrades I’m comfortable starting from a blank repository and building the product from scratch, or joining an existing application and figuring out what needs to change without turning every problem into a rewrite. ✦ SHOPIFY 🔹 Shopify stores and Shopify apps 🔹 Shopify Plus and large product catalogues 🔹 Liquid, custom themes and storefront development 🔹 Shopify APIs and webhooks 🔹 App authentication, billing and background processing 🔹 Store migrations and custom business workflows 🔹 Storefront performance and conversion-focused improvements I’ve built public Shopify apps from scratch and worked on stores with 10,000+ products, so I’m comfortable with both the customer-facing storefront and the systems behind it. ✦ AI / LLM INTEGRATIONS 🔹 Claude API and OpenAI API 🔹 AI-assisted workflows and automation 🔹 RAG and embeddings 🔹 Structured outputs and validation 🔹 Retries, fallbacks and usage controls 🔹 Production AI features and monitoring The goal is not simply connecting an AI API. It is making the feature reliable enough to become part of the actual product. ✦ PROVEN WORK 🔹 Long-running Rails products and SaaS platforms 🔹 Enterprise SaaS used by 100,000+ users 🔹 Shopify stores and public Shopify apps 🔹 Complex API and webhook integrations 🔹 Product sync and data-heavy systems 🔹 Rails upgrades and legacy codebases 🔹 Production AI / LLM features I’ve worked on products where stability matters just as much as new development, including performance problems, migrations, integrations, and production issues. ✦ HOW I WORK ✓ Understand the existing system before changing it ✓ Build the core architecture properly from the start ✓ Work on staging or duplicate environments first ✓ Test changes before release ✓ Flag problems early rather than after production breaks ✓ Use Claude Code and Cursor to move faster, while reviewing and owning the code that ships 📩 Send me a short brief about what you’re building or what needs fixing, and I’ll come back with a practical technical approach.
