Alexei Hernandez

I’m a Senior Full Stack Developer with 6+ years of experience building end-to-end solutions in the JavaScript/TypeScript ecosystem, including React, Node.js, and NestJS. I focus on reactive interfaces, scalable backend architectures, and disciplined best practices shaped by agile methodologies.

At my current role, I translate complex business needs into functional software, improving frontend performance by optimizing component lifecycle and state management to reduce unnecessary re-renders across high-data ERP modules. I also design reusable, modular interface architecture using Clean Architecture principles to keep visual consistency as the product grows.

Previously, I led frontend work for a CRM tool and delivered dynamic real-estate inventory visualization by integrating complex RESTful services. I’ve contributed to backend scalability through maintenance and enhancement of the system core, building and optimizing endpoints, and integrating with SQL and NoSQL databases using Express and NestJS.
