About

Professional summary

I am a Systems Engineer and Full Stack Developer with more than two years of hands-on experience building custom web solutions for real clients. My primary specialization is frontend development with Astro, React, TypeScript, HTML, and CSS, while I also contribute to backend development using Python, Flask, and PHP.

I have delivered responsive business and corporate websites focused on usability, mobile responsiveness, lead conversion, and performance. I translate stakeholder requirements into production-ready web experiences and use AI-assisted prototyping tools to accelerate design iteration.

My experience includes e-commerce and business operations solutions, including WooCommerce integrations, catalog management, custom quotation tools, and ERPNext implementations. I have helped improve quotation and conversion processes while supporting inventory accuracy and real-time stock management.

I am comfortable working across the full stack in Linux environments and collaborating through agile methodologies such as Scrum and Kanban. I use Git-based version control workflows and have experience with GitHub, GitLab, and Jenkins.

I hold a Bachelor of Software Engineering degree and completed Full Stack Developer training at 4Geeks Academy. I am motivated to continue building reliable, scalable, and user-focused web applications for businesses and clients.
