Leandro Nascimento Camargo

Full Stack Web Developer @ Lawmatics

I've gone through two different stages in the company so far: the first one was more product driven, where I developed new features (using Rails and React), services, fixed bugs and improved performance of existing features and services. I worked a lot with a variety of third party integrations we have and developed some of them from scratch, including the RingCentral one, handling real-time ingoing/outgoing phone calls and their multiple events.

The second stage happened when I moved into the Reliablity team (of which I'm still part), as soon as it was created in the company. There I did and still do many important performance optimizations related to PostgreSQL, Redis, Sidekiq, Elasticsearch and many thorough ActiveRecord analysis & optimizations in our Rails codebase. I really enjoy doing this kind of work: monitoring, analyzing and investigating metrics, doing important refactoring of code, planning data modeling and system architecture in general, planning a rework of parts of the system that are not performing well, like I'm currently doing with our CSV based importing system, which is a core feature to our business, but also contains several performance issues at the moment.
