Hi, I'm Murilo Kendjy — Software Developer (Go & JS/TS)

Backend focused, I build reliable applications and systems end-to-end, from requisites to deploy.

Strong focus on clean code, testing, scalability, and maintainability.

About me

I'm a backend-focused developer with 3+ years of experience building production-grade systems in a small but high-demand environment, where I’m responsible for the entire web stack: backend development, frontend implementations, infrastructure, CI/CD, monitoring, and deployments.

Working mostly alone taught me how to own a system end-to-end — from database design to cloud architecture, from code quality to production stability. I enjoy designing clear APIs, writing maintainable services, and improving reliability through good engineering practices.

Recently I’ve been focusing on Go, distributed architectures, testing strategies, and backend scalability

Techs I work with

Backend: Go, JavaScript/TypeScript, Node.js (NestJS, Express, Fastify)

Data: PostgreSQL, MySQL, Redis, DynamoDB

Cloud & Infra: Docker, Docker Compose, Nginx, MinIO, VPS deployment, AWS (CDK, EC2, S3, Lambda, API Gateway)

Architecture: REST APIs, Clean Architecture, Domain-Driven mindset

Observability: Grafana, Prometheus, Loki

Frontend: Angular, React, Next.js

Other: WebSockets, queueing (RabbitMQ), third-party API integrations, payment gateways (PSP), Google Maps

API Testing: Unit & integration tests (Go / Jest / Vitest)
