Profile Description

I build custom web applications, automation systems, and AI-powered solutions that help businesses improve their workflows and operate more efficiently.

My development journey started with traditional web technologies such as PHP, MySQL, HTML, and CSS. Over time, I moved into modern full-stack development using React, TypeScript, FastAPI, PostgreSQL, and Go for building reliable and scalable applications.

I have experience building complete business systems, including dashboards, internal tools, client portals, and workflow platforms. I also handle deployment and infrastructure using Linux, Docker, Podman, Nginx, Caddy, VPS environments, and cloud services.

For AI and automation, I build practical solutions using LLM integrations, APIs, and custom workflows that reduce repetitive tasks and improve productivity.

Some of the business applications I have built are available as working demos, including systems developed for different industries such as operations, consulting, and business management.

I can help with:

- Full-stack web application development
- Backend APIs and system integrations
- AI automation and workflow improvement
- Database design and application architecture
- Deployment, hosting, and infrastructure management
- Technical documentation and process improvement

I combine software engineering skills with real business operations experience, allowing me to build solutions that are not only technically sound but also useful for everyday business needs.
