Hi, my name is

Wilfred Almeida.

LFX'23 Mentee @ CNCF Harbor | NodeJS-Golang Backend + DevOps | Web3 Enthusiast | Learning Rust

I am a NodeJS-Golang Backend Developer with experience in Flutter & Cloud as well as, Solana.

I'm looking for full-time Remote Jobs.

I like finance and can go on talking for hours about Investment, Personal Finance, Stock Market, Global Economies etc.

About Me

As a full-stack mobile app developer with over a year of practical experience in Flutter and Node.js, I have a passion for building and improving projects. My applications have been downloaded over 10,000 times on the Google Play Store.

In addition to my expertise in REST APIs and deployment using NGINX, Docker, CPanel, and CyberPanel, I have recently gained experience working with Kubernetes, and implementing CI/CD pipeline on a Debian 11 VPS server.

Throughout my career as a freelancer and intern, I have always prioritized upskilling myself while providing value to my clients. I am currently learning about System Design and striving to improve my skills in this area.

I recently open-sourced unkey-go to further its development.

I enjoy helping people and communities, and I am active in various communities online. With over 500+ reputation points on StackOverflow, I am dedicated to providing helpful and reliable solutions to others.

My strong understanding of Computer Networks, gained through years of internet usage, has equipped me with the knowledge necessary to succeed as an Internet Service Provider ISP

Here are a few technologies I’ve been working with recently:

  • Mobile: Flutter
  • Backend: Golang, NodeJS
  • Cloud: Linux, NGINX
  • DevOps: ArgoCD, Docker, Harbor, Kubernetes
  • Databases: Firebase, MongoDB, PostgresSQL
  • Platforms: Cloudflare, GitHub Actions
