You will get custom AI Agents or Assistants – Local, Private, Multi-Tool Automation
Project details
I build custom private AI Agents that run locally on your computer or VPS — no cloud dependency, no data leaks. (unless cloud is what you really want)
What sets me apart:
• Truly private & secure (everything stays on your machine)
• Goal-driven autonomous behavior (you give a goal, the agent plans and executes steps safely)
• Advanced long-term memory so it actually remembers your business/life over time
• Safe, permission-based tools (email, calendar, Slack, Notion, browser, files, etc.)
• Beautiful custom desktop or web interface
Perfect for solopreneurs, small teams, and agencies who want powerful automation without security risks or recurring cloud fees.
I deliver clean, well-documented work with full source code and ongoing maintenance/support options.

About John
Sr. Systems Architect | Py/Rust/C++ | AI/ML | Zero-Backend Solutions
Tampa, United States - 7:48 am local time
As a Sr. Systems Architect, Data Scientist, and Full-Stack Engineer, I bring a unique blend of expertise in high-performance computing, memory optimization, and secure infrastructure. I design and implement systems that not only meet stringent technical requirements but also drive commercial success.
Why I’m Different:
While many developers integrate APIs, I build solutions from First Principles—addressing challenges like:
Running advanced 7B LLMs on edge devices
Securing networks against zero-day vulnerabilities
Creating crash-proof Rust backends
Delivering seamless full-stack applications
My background, including the Teixido-Boreal Paradigm in deep-tech research, ensures I apply scientific rigor to all stages of software development and system architecture.
Core Services
🚀 AI & LLM Optimization (Python/PyTorch)
Model Quantization & Pruning: Deploy models on edge devices without sacrificing accuracy.
Memory Efficiency: Pioneered solutions that reduce VRAMusage by 23x.
Agentic Workflows: Develop autonomous agents that handle complex tasks independently using LangChain/LangGraph.
🦀 High-Performance & Full-Stack Systems (Rust/WASM/C++ & Node.js/JavaScript)
Zero-Backend Architectures: Utilize Rust/WASM for secure, efficient browser-resident engines.
Full-Stack Development: Build complete applications using modern frameworks (e.g., Ruby on Rails, React), from backend services to user interfaces.
System Daemons: Design and implement crash-safe, efficient services for Linux/Windows systems.
🛡️ Cybersecurity & Anomaly Detection
Zero-Sh Threat Detection: Craft detection engines for identifying novel threats through behavior-based analysis, achieving a verified 97% recall on zero-day threats.
⚡ Hardware & Signal Processing (Verilog/FPGA)
Design synthesizable IP cores tailored for low-power signal processing and anti-jamming applications in hardware startups.
