WebSocket-based messaging for 10K+ concurrent users
AWS infrastructure: EC2, S3, X-Ray, CloudWatch
Comprehensive Swagger API docs — cut third-party integration time by 50%

Recently worked on BES Vinyl - a large-scale ecommerce infrastructure project built around Shopify, FileMaker Server, and AWS to support a rapidly growing online vinyl record business.
The project involved restoring and stabilizing a mission-critical FileMaker PIM system, rebuilding backend workflows, and implementing automated API-driven synchronization between Shopify and the internal product database for inventory, pricing, metadata, supplier imports, and catalog management.
Beyond the storefront experience, the real focus was operational scalability - reducing manual processes, improving data reliability, and creating a centralized commerce ecosystem capable of handling large product volumes efficiently.
Projects like this are where ecommerce, automation, and systems architecture come together to create measurable business impact. 🚀
Everything feels balanced, refined, and professionally designed 💯
CRM & Online Appointment Booking Platform
Appointer is a CRM and online appointment booking platform for service-based businesses such as beauty salons, clinics, massage studios, tanning salons, dental offices, service stations, and other appointment-driven companies.
The platform helps businesses manage client bookings, employee schedules, customer records, reminders, sales, and daily operations from one centralized system. It provides online booking for customers, a visual calendar for administrators, client history tracking, SMS visit reminders, and tools to reduce manual work for business staff.
I worked on this project as a Full Stack Developer, contributing to both frontend and backend development. My work focused on building a reliable, responsive, and easy-to-use web platform for appointment management, CRM workflows, scheduling, and customer communication.
The project required strong attention to usability because business owners and administrators needed to manage appointments quickly throughout the day. I helped create smooth flows for booking, calendar management, customer tracking, employee schedules, and business analytics.
