About Me
I'm Prinze Mikhail Sadsad, a Systems Engineer with deep Systems Administration experience. I build and operate end-to-end production systems — from architecting full-stack applications and designing databases, to provisioning Linux servers, managing CI/CD pipelines (Jenkins, GitHub Actions), working with Docker and Nginx, and keeping production running reliably. My work spans both sides of the software delivery lifecycle: development and operations.
My engineering foundation is rooted in computer science and hands-on experience shipping production software. I also incorporate AI-assisted development tools into my workflow — they accelerate prototyping, debugging, and iteration, letting me focus on higher-level design and architecture decisions. Whether I'm designing system architecture, optimizing database queries, debugging a deployment pipeline, or troubleshooting server hardware, the approach is the same: build it right, keep it running, and make it better over time.
Professional Summary
Systems Engineer with deep Systems Administration experience — designing, building, deploying, and operating production business systems across the full software and infrastructure stack. I bridge development and operations, delivering end-to-end solutions that are architecturally sound, operationally reliable, and built for real-world use. My dual competency covers full-stack application development, database design, CI/CD pipelines, server provisioning, and production support.

Frequently Asked Questions
Find quick answers about my services, tech stack, process, and how I collaborate with startups and teams. These FAQs keep everything transparent so you know exactly what to expect before we start working together.
I offer full-stack software development, infrastructure setup and administration, database design, and deployment pipeline configuration. My services range from building complete business applications to setting up self-hosted infrastructure, CI/CD pipelines, and production support. I focus on clean, maintainable code, reliable infrastructure, and solutions that are built to run in real-world operations.
I work across two tracks. In my enterprise work, I primarily use PHP (Vanilla & Laravel), C# .NET, and SQL for building production business systems. In my personal projects, I work with Flutter/Dart, PostgreSQL/Supabase, and modern full-stack tooling. Across both, I handle deployment pipelines, server infrastructure, and production operations — so I'm equally comfortable with application code and the infrastructure that runs it.
Absolutely! As the Founder of The Heedful, I have firsthand experience building a startup from the ground up. I understand the unique challenges startups face: tight budgets, fast iteration, and the need for scalable solutions. I can help you build MVPs, compelling landing pages, and web architectures that grow alongside your product without requiring a complete rebuild later.
I use a "Rapid Prototyping" approach that gets you a working version fast. I build a live, interactive skeleton early in the process so you can see and interact with the layout on real devices before we dive into final details. This way, you can provide feedback early, and we can iterate quickly. Once the structure is solid, I polish every interaction, animation, and detail to make it production-ready.
Yes — I handle the full deployment lifecycle. I manage self-hosted infrastructure (Coolify, Docker), configure CI/CD pipelines, set up domains with SSL, and maintain production servers. I'm experienced with both modern platforms (Netlify, Vercel) and traditional hosting for PHP/.NET applications. I can take your application from development to a fully deployed, production-ready state — including ongoing infrastructure maintenance.
You can contact me directly through this website's contact form or reach out via email. I'm always open to discussing new projects, whether it's a quick landing page, a full web application, or a long-term collaboration. For larger projects, we can schedule a discovery call to align on goals, timeline, and expectations.
Timelines depend on scope, but small landing pages usually take around one to two weeks, while more complex web applications can take several weeks or more. I focus on keeping communication open, sharing progress as I go, and aiming to give you something you can click through and test as early as possible.
The Heedful is a startup digital platform I founded that empowers students and professionals through skill development, mentorship, and community support. We organize workshops, provide learning resources, and build connections to help individuals thrive in technology and beyond. Leading this initiative has given me deep insights into startup challenges, which I bring to every project I work on. You can learn more at our website.
Yes! I include reasonable revisions during the development process to ensure the final product meets your vision. After launch, I provide documentation and can offer ongoing maintenance and support packages if needed. I believe in building long-term relationships with clients, so I'm always available to help with updates, bug fixes, or new features.
