Boris Aghajanyan

I’m a senior full-stack engineer with 10+ years of experience designing and delivering high-scale web applications across the full stack. I specialize in backend architecture, microservices migration, and API design, with a track record of building systems that improve performance, reliability, and business outcomes. I’ve worked in agile, cross-functional teams as both an individual contributor and a domain expert, and I leverage AI tooling throughout the development cycle to accelerate delivery without compromising quality.

At Wayfair, I led the redesign and migration of fulfillment-domain services from a PHP monolith to 10+ decoupled microservices (Java Spring Boot), improving scalability, deployment independence, and long-term maintainability. I rebuilt core fulfillment systems, contributed to initiatives driving millions of dollars in additional annual revenue, and reduced critical fulfillment pipeline response times from several minutes to 100–300ms. I also migrated front-end services to TypeScript, served as a primary point of contact across engineering, product, and operations, and onboarded and mentored new teams through multiple reorganisations.
