That typically includes:

Cleaning up repo and system structure
Defining architecture and workflows
Identifying missing components
Improving or building automation pieces
Writing clear documentation
Creating developer handoff + operational clarity
Ideal projects
I’m especially interested in:
AI automation systems
API-connected applications
Developer tooling
Workflow automation
Local AI / LLM systems
Technical infrastructure design
Turning prototypes into production-ready systems

The simplicity here is absolutely striking!
I'm still early in my career — and that's exactly what makes this stage exciting.
I'm a full-stack developer with 3+ years of professional experience, primarily working with PHP, Laravel, Symfony, Vue.js and APIs.
I've worked on SaaS products, web applications, backend systems and integrations.
More recently, I've been experimenting with something that I find particularly interesting: combining software development, automation and AI.
I like taking a problem that currently requires several manual steps and asking:
"Could a system just do this for us?"
Sometimes the answer is a simple API integration.
Sometimes it's an n8n workflow.
Sometimes it's an AI model inside a larger application.
And sometimes it requires building an entire product around the process.
I'm currently exploring where this intersection of development + automation + AI can take me next.
If you're building something interesting, I'd love to hear about it.
Automating Resume Screening with AI
I recently worked on a recruiting bot that uses n8n to connect Gmail, Groq AI, and Google Sheets. The goal was to automate the resume screening process and save time for the HR team. I'm happy to say that it's working smoothly and has already saved a significant amount of time. The tech stack was a bit challenging to set up, but it was worth it in the end.
