Andrei Kniazev

I am a Full-Stack Developer with over six years of experience designing, developing, and optimizing scalable applications for B2B and B2C products. I specialize in delivering low-latency, high-performance solutions across frontend and backend stacks.

My work spans React, MobX, Node.js, Express, PostgreSQL and related technologies, and I have deep domain experience in e-prescribing, fintech, e-commerce and high-growth environments. I focus on measurable improvements such as latency reduction, cost optimization, and enhanced user experience.

In recent roles I developed opt-in notification webhooks, implemented a prescription capture system that sped prescribing fourfold, reduced query latency by 10x, and managed e-commerce applications serving millions of users while introducing monitoring and logging to cut debugging time significantly.

I collaborate effectively with cross-functional teams using Agile practices, deliver secure role-based access controls, integrate third-party APIs to boost sales and logistics performance, and continuously improve product usability and adoption through thoughtful front-end and backend engineering.
