I've delivered production systems that reduce costs, automate workflows, and measurably improve performance. From a Shopify to MedusaJS platform migration to a containerized LMS and headless storefronts serving 200+ products. I combine production engineering with first-hand business operations experience. Co-managing a restaurant has given me real-world insight into customer retention, loyalty incentives, and the operational constraints that software has to actually solve for. I thrive in Agile product teams, communicate clearly across disciplines, and care about shipping work I'm genuinely proud of. Whether you need a scalable e-commerce platform, an internal tooling system, or a content-driven application, I'd love to help bring your vision to life. ## Experience ### Senior Software Engineer, Aira Publishing Period: June 2024 — Present Technologies and areas: Next.js, TypeScript, React, GraphQL, MedusaJS, Docker, Nginx, Redis, Django, Django REST Framework, GitHub Actions - Spearheading platform migration from Shopify to Next.js + MedusaJS, eliminating vendor lock-in and gaining full control over the deployment pipeline, codebase, and payment processing workflows - Architecting and deploying a containerized application stack using Docker, Nginx reverse proxy, and Redis caching, enabling zero-configuration environment parity across development, staging, and production - Designing and building a full-featured learning management system (LMS) with Django and Django REST Framework, featuring course management, enrolment workflows, lesson progress tracking, and role-based access control - Engineered a headless e-commerce storefront with React, TypeScript, and GraphQL, integrating REST APIs with reusable UI components to support 200+ products with server-side rendering that improved Largest Contentful Paint - Collaborating with cross-functional product and content teams to translate complex business requirements into scalable data models and reusable component libraries, accelerating time to market ### Software Engineer, Scholarly Elite Tutoring Period: June 2020 — June 2024 Technologies and areas: Ruby on Rails, PostgreSQL, JavaScript, REST APIs, RSpec, Sidekiq, Active Storage - Designed and shipped an API-driven content platform in Ruby on Rails that automated personalized tutoring packet generation, replacing a manual workflow and reducing document assembly time from hours to seconds - Developed educator-facing admin tools for managing hierarchical curriculum structures (Closure Tree) and file attachments (Active Storage), enabling personalized learning materials at scale - Refactored monolithic controller logic into a testable service layer with versioned RESTful APIs, improving code maintainability, test coverage (RSpec), and onboarding speed for new developers - Implemented asynchronous PDF compilation using Sidekiq background jobs with real-time progress feedback via Server-Sent Events (SSE), cutting export wait times for large document batches - Mentored junior developers through pair-programming sessions and code reviews, establishing coding standards that improved team velocity and code quality ### Co-Managing Partner, Danny’s Fish & Chips Period: May 2019 — Present Technologies and areas: Operations, Customer Engagement, Digital Marketing - Co-managed daily operations of a high-volume restaurant with a long-standing repeat customer base - Built first-hand understanding of customer retention, promotions, loyalty incentives, and real-world operational constraints - Evaluated and adopted digital tools for marketing, operations, and customer engagement with strict focus on ROI, reliability, and staff usability ### Business Development Manager, Scholarly Elite Tutoring Period: Mar 2018 — May 2024 Technologies and areas: CRM, Data Analysis, Strategic Planning, Marketing - Leveraged data-driven strategies to optimize the client conversion process, resulting in a 14.7% increase in conversion rates - Designed and executed a strategic brand extension plan for the company's educational publishing division - Conducted in-depth research and led the implementation of CRM software to strengthen data collection; collaborated with the marketing team to refine client acquisition strategies in alignment with the company's long-term vision ## Project details ### Drenova Group Real Estate Platform Built a real-estate platform for GTA/York Region with Sanity CMS, AMPRE/MLS listing sync, Redis-backed listing cache, lead capture workflows, listing inquiry forms, ISR revalidation, and compliance-aware address suppression.
