Hi, I'm Melvin Jones Gallano Repol
Freelance Software Engineer | DevOps
I specialize in building robust, scalable software solutions that solve real-world problems. With a passion for technology and a commitment to excellence, I bring ideas to life through code.
Whether it's developing web applications, optimizing systems, or diving into data analytics, I'm here to help you achieve your goals. Let's create something amazing together!

I apply engineering principles to design, develop, test, and maintain reliable software systems. My focus is on creating efficient solutions that meet customer needs, using modern tools and technologies to ensure software quality and performance.
I build dynamic websites and web applications using technologies like HTML, CSS, JavaScript, PHP, MySQL, NodeJS, Firebase, and MongoDB. My experience covers both frontend and backend, enabling me to deliver complete, scalable web solutions.
I optimize websites to improve their visibility in search engine results. My SEO process includes refining content, structure, and technical elements to drive organic traffic and enhance digital marketing efforts.
I transform raw data into actionable insights to support decision-making. Using a range of tools and processes, I identify trends, solve problems, and deliver valuable information for business growth.
I design and program embedded systems using Arduino, integrating hardware and software for IoT, robotics, and automation. My expertise includes selecting components, optimizing code, and troubleshooting hardware-software interactions.
I assemble, configure, and repair computer systems, ensuring optimal performance and security. My skills include diagnosing issues, installing operating systems, and using software tools to maintain reliable hardware and software environments.
I take action. I embrace failure. I grow wiser.
Every build I undertake is guided by a few core principles:
- KISS — Keep It Simple, Stupid.
- YAGNI — You Aren't Gonna Need It.
- DRY — Don't Repeat Yourself.
If you are able to clearly write down your problem, then it is already half solved.

My Gaming Activities
I also enjoy gaming and often share my gaming activities. Check out my latest games and achievements.
I’m building Hall of Codes — an open-source playground for developers, creatives, and problem-solvers. It’s where ideas turn into projects, and projects turn into opportunities to learn and collaborate.
If you love building cool things, exploring new tech, or just geeking out over code, you’re welcome to join the journey.
