Senior Full Stack Engineer specializing in retention marketing, performant frontends, and resilient server-side systems.
What I'm looking for
I’m a Senior Full Stack Engineer with 7 years of end-to-end web and mobile application development experience. I focus on building performant frontends, engineering resilient server-side solutions, and managing robust data layers that help teams ship with confidence.
In recent work, I’ve owned development and deployment of full-stack applications at Plan A Technologies, driving doubled user engagement and tripled sales revenue. I established automated workflows, segmentation, and list logic with Klaviyo and Shopify, and built scalable, secure backend APIs with Node.js, Express, and NestJS—handling high traffic with reduced latency.
I also bring a strong retention marketing and customer journey optimization angle, using data-driven strategies to increase conversion rates and reduce churn. Across my roles, I’ve optimized database performance with PostgreSQL/MySQL/Redis, implemented testing and QA strategies, led code reviews, and mentored junior engineers to promote continuous improvement.
