Hi, I'm Harold Eustaquio, a software developer with a long-standing passion for technology. I started programming at 13 years old, experimenting with command-line tools and small scripts, and that early curiosity eventually grew into a professional career by the age of 17. Since then, I’ve focused on building systems that emphasize scalability, performance, and long-term maintainability.

My technical expertise spans several categories:

  • Programming Languages: TypeScript, JavaScript, Python C, C++, PHP, Rust
  • Frameworks: NestJS, Fastify, ExpressJS, Laravel, Flask, Django, VueJS, NuxtJS, ElectronJS, LernaJS, Tauri, Astro
  • Databases: PostgreSQL, MySQL, MongoDB, Firestore, OracleDB
  • ORM: Sequelize, Prisma, Eloquent, Mongoose, TypeORM
  • Container: Docker, Docker Swarm
  • Cloud Computing: AWS, Linode, Heroku, Vercel, Render, DigitalOcean
  • Infrastructure: Prometheus, Loki, Grafana, Wazuh, Portainer, Seafile, Nextcloud
  • CMS: Drupal, WordPress
  • Blockchain & Smart Contracts: Rust-based smart contract development

I'm currently developing Aegisr, an ultra-fast key–value database (KVD) built entirely with Rust, designed to leverage in-memory storage for maximum performance and minimal latency. The project focuses on providing developers with a high-performance data storage solution that can handle large-scale workloads efficiently while remaining highly reliable and easy to integrate into modern applications.

I’m particularly drawn to designing scalable, modular architectures that anticipate future growth and change. I strive to write clean, maintainable, and future-proof code that reduces the need for frequent refactoring, making it easier for teams to extend and improve systems over time without introducing complexity or instability.

In my free time, I love to explore new technologies and experiment with different programming languages to improve my skills. My passion for coding drives me to deliver high-quality software solutions that meet my clients' requirements and exceed their expectations.

If you're looking for someone who values performance-oriented engineering and thoughtful systems design, I’d be excited to collaborate with you.
