 Web Development & Security

Corporate Website — Full Development Lifecycle
Led complete website development over initial 3-month period. Started with
custom-coded solution built from scratch (HTML/CSS/JS, custom backend), then
strategically migrated to WordPress for easier content management and team
autonomy. Handled full process: UX/UI design in Figma →
interactive prototyping
→ custom development → WordPress migration → production deployment. Result:
enhanced company's online presence and enabled non-technical staff to manage
content independently.

Security Testing & API Quality
Conducted comprehensive API testing using Postman throughout development phases.
Performed security vulnerability assessments using Burp Suite before each
deployment, identifying and remediating potential risks.
