At BMO Private Wealth, I led the development of secure, cloud-native applications that support investment management, estate planning, and tax strategy for high-net-worth clients. I built scalable backend services using Python, C#, and Node.js, deployed on AWS with EC2, Lambda, and Kubernetes. On the frontend, I developed advisor tools in React that deliver real-time portfolio analytics and streamline client workflows. I also integrated market data providers and internal systems, contributed to infrastructure automation through CI/CD pipelines, and enforced cloud security standards using Ansible and GitHub Advanced Security.

At Book4Time, a global SaaS provider for the spa and wellness industry, I helped architect and scale the company’s core booking platform, which handled over a billion API requests monthly and processed $20M+ in daily transactions. I built asynchronous APIs in C# with Redis caching and multithreaded background jobs. I led the design and launch of “Online Booking X,” a mobile-first React app with SSR and OAuth sync that allowed full UI customization. My work also included integrating six payment gateways, refactoring legacy services, and improving infrastructure through test-driven development and infrastructure-as-code.

At CIK Telecom, I modernized legacy customer systems using the .NET MVC stack and React, focusing on performance, usability, and automation. I built a self-serve payment portal integrating PayPal, which helped reduce missed payments by $200K/month. I also developed MQTT-driven warehouse automation tools in C#, which cut the shipping backlog by 60%. Additionally, I created customer-facing portals, AI chat interfaces, and internal dashboards, improving support workflows and enabling real-time service management.
