Zenni Optical - ecommerce for eyewear

Performed tasks such as rate limiting and distributed locking via Redis and migrated the entire Redis Cache to cluster mode.

Joined as a senior software developer and worked on their core payment infra. I was later assigned to lead a team for a new product called Smart Routing.

Migrated a massive monolith codebase to a distributed microservice architecture. The main challenge was to migrate from the old system to the new one and develop this new product and integrate it progressively.

Started building the team even without an engineering manager. Handled the hiring, set up SOPs with the PM, and created a plan.
