developer_profile.sh
I am a Computer Engineer specializing in AI Automation, Software Development, and Cybersecurity. I am experienced in developing reservation systems, inventory management platforms, hardware-integrated solutions, and automated workflows that improve efficiency and streamline operations.
I am proficient in Python, JavaScript, Django, MySQL, and modern web technologies, with a strong focus on secure, scalable, and user-friendly applications. I am highly skilled in AI workflow automation (e.g. n8n, Zapier, GHL), Cisco networking, network security, and hardware troubleshooting.
Core disciplines
What I specialize in
AI Automation
Workflows, agents, and integrations e.g. n8n, GHL, and Zapier. That remove repetitive work.
Cybersecurity
Cisco networking, defense, and secure-by-design thinking.
Full stack

Autonomous Executive AI Swarm
Workflow Automation AI AgentsAn enterprise-grade multi-agent automation system that utilizes a supervisor-subagent architecture to handle incoming user requests via Telegram. The system features an intelligent "Main Brain" router that intercepts messages, enforces strict content guardrails, and dynamically delegates specialized communication, scheduling, and database tasks to dedicated sub-agents before logging execution data.
Key Features & Implementations
- Supervisor-Subagent Routing Architecture: Built a central "Main Brain" router using advanced LLM logic to classify intent and hand off tasks to specialized, downstream sub-agents (Email, Calendar, and Contacts).
- Proactive UX & Content Guardrails: Integrated real-time "Typing..." indicators to optimize user experience alongside an automated content filtering layer to catch policy violations prior to API execution.
- Specialized Multi-Agent Skillsets: Engineered modular agents with granular tools, including a Google Calendar agent for availability and scheduling, a Gmail agent for inbox management, and an Airtable CRM agent for data synchronization.
- Asynchronous Error Handling & Logging: Structured a dual-path outcome tree that sanitizes payload data and logs performance metrics to Google Sheets on success, while deploying immediate feedback alerts on execution errors.

IT Fundamentals
How I work
Built for clarity, not chaos
Precise
Small details in UI, security, and code structure. Because sloppy work doesn't scale.
Transparent
Clear communication, honest timelines, and documentation you can actually read.
Reliable
Long-term maintainability over quick hacks. Still fast, just not reckless.
Services
What I Offer
Available for permanent work and freelance opportunities.
Web Development
Full-stack web applications built with modern technologies. From landing pages to complex web apps, I deliver responsive, performant, and maintainable solutions.
AI & Workflow Automation
Streamlining complex processes using intelligent automated workflows, AI API integrations (OpenAI/Claude), custom Python/JS scripts, and smart agent systems to eliminate repetitive manual tasks.
Frontend Development
Beautiful, interactive user interfaces using React, Next.js, and Tailwind CSS. Focus on accessibility, animations, and pixel-perfect implementation.
Backend Development
Robust APIs and server-side solutions with Node.js, Express, and MySQL. Clean architecture, proper authentication, and optimized database design.
Responsive Design
Mobile-first design approach ensuring your application looks and works great on all devices — from smartphones to large desktop screens.
UI/UX Implementation
Converting Figma designs into pixel-perfect, interactive interfaces. Attention to detail in typography, spacing, and micro-interactions.
