About this gig

Need a custom web app, dashboard, or internal tool built around your businessnot a generic template?


I build secure full-stack web applications that solve real operational problems. Whether you need an MVP, client portal, business dashboard, API integration, or workflow automation, I can manage the complete process from requirements and architecture to implementation, testing, documentation, and handover.


What you can expect:

Responsive, practical user interfaces

Authentication and role-based access

Well-structured databases and API integrations

Clean, maintainable, documented source code

Clear communication and realistic milestones

Testing and deployment support


My core stack includes TypeScript, React, Next.js, Node.js, PostgreSQL, and Supabase.


What sets me apart is my security-first mindset: I have advanced training in cybersecurity and four years of experience teaching cybersecurity. I build with reliability, maintainability, and sensible security practices in mind from the start.


Please message me before ordering. I will review your requirements, recommend the right package, and confirm the scope, price, and delivery plan.
