Mission Control
Problem
Build a security-hardened control plane for autonomous AI agents, tasks, and orchestration workflows in a 7-day hackathon sprint using only Hermes Agent
Core Technologies
GoGinSQLiteGorilla WebSocketbcryptHermes AgentbluemondayVanilla JSHTMLCSS
Solution
- Voted Top 5 (tied 4th) of 6,950 contestants in the AI Agent Builders hackathon — built in a 7-day sprint with 3 days of active development.
- Full-stack AI agent orchestration dashboard: agent registration, task kanban, real-time WebSocket updates, research and content workflows, and automation triggers.
- Defense-in-depth security: API key + session token auth, RBAC, prompt-injection detection, XSS sanitization, rate limiting, and hardened WebSocket origin checks.
- 12/12 security test cases passed, including prompt injection, stored XSS, RBAC escalation, and unauthorized access.
- ~3,900 lines of Go across a modular backend (handlers, models, security, database), plus a NASA-inspired vanilla-JS frontend.
Multi-Agent Supervisor Workflow
Problem
Implement a genuine supervisor → subagent architecture locally — independently compiled agents coordinated by a planner, not a single LLM with tool routing
Core Technologies
LangGraphLangChainOllamaPythonDuckDuckGo Searchpython-dotenvDocker
Solution
- True multi-agent system: Researcher, Analyst, and Writer are each independently compiled StateGraphs with their own state, nodes, and edges.
- Supervisor inspects shared state at every step, routes to the next subagent, and loops until the task is complete — running entirely on a local Ollama model.
- Code-level guardrails (not prompt-only): force Writer before finish, prevent infinite loops, detour math tasks through Analyst, and preserve exact dollar figures and units.
- Inline observability: agent traces, debug logs, context/token estimates, and warnings when guards override the model's routing decisions.
- Fully self-hosted — no paid LLM API; DuckDuckGo for factual lookup; Docker Compose for reproducible runs.
Applied Math Mastery
Problem
Build a full-stack gamified math learning platform that connects curriculum mastery to real-world careers and measurable progress
Core Technologies
ReactTypeScriptViteGoFiberREST APIJWTVercelZustandPlotly.jsFramer Motion
Solution
- Full-stack learning platform: React/TypeScript frontend with Vite, Go/Fiber REST API, JWT authentication, and Vercel deployment.
- Forge Mode teaches Algebra, Calculus, Statistics, Geometry, etc. through concept visuals, Plotly simulations, and adaptive multiple-choice exercises.
- Career Explorer maps each subject to real roles with salary data and estimated mastery-based salary boosts.
- Gamified progress system with XP, levels, streaks, daily challenges, mastery badges, achievements, and weekly/all-time leaderboards.
- Protected user dashboard and progress APIs with CORS, middleware, and rate limiting — open source and free for educational use.

Relationhance
Problem
Architect, Design, and Deploy Startup Tech Business with integrated AI and Stripe for Payments.
Core Technologies
ReactTypeScriptGoMongoDBJWTStripeLLM Integration
Solution
- Full-stack startup: React/TypeScript frontend, Go backend, MongoDB, and JWT authentication.
- Integrated real LLM models for AI-powered task and reward suggestions.
- Stripe payments wired end-to-end for B2B and B2C monetization.
- B2B/B2C platform targeting the $250B+ consumer tech, edtech, workplace, military, and government training spaces — designed for everyone in life, family, friends, relationships, education systems, military, work teams, and HR training systems.
- Gamifies relationship building, networking, and collaboration to drive measurable gains in quality of relationships, closer communities, stronger bonds, leadership effectiveness, work force retention, and team morale.

Who I Am
01- Full-Stack Engineer and Founder. Built and shipped systems serving hundreds of thousands across YouTube, Applied Math Mastery, Relationhance, and tech blogs. Voted Top 4 of 6,950 in the AI Agent Builders hackathon with Mission Control.
- Specialized in Go, TypeScript, JavaScript, Python, SQL/NoSQL, and C/C++, with AI engineering across LangChain, LangGraph supervisor/subagent systems, MCP servers, local Ollama models, RAG pipelines, and vector databases (ChromaDB).
- CourseCareers backend specialization with a 4.0 GPA, trained by former Microsoft and IBM engineers. BA Economics, University of Arizona, including a 50-page SAS thesis in quantitative data analysis.
- Lead Engineer & Technical Writer at nickalvarez.dev/blog. Top 5% on LeetCode, Top 2.2% on Codewars. Completed a 14-year Khan Academy math curriculum in 15 months.
- Mentored hundreds of thousands of learners through a top #4,400 YouTube channel with 970K+ players coached and 10M+ views.
Selected Projects
02- Mission Control. I built a security-hardened AI agent orchestration dashboard in Go (Gin, SQLite, Gorilla WebSocket) with RBAC, prompt-injection detection, XSS sanitization, and real-time updates — finishing Top 5 (tied 4th) of 6,950 in the AI Agent Builders hackathon, with 12/12 security tests passed.
- Multi-Agent Supervisor Workflow. I implemented a genuine LangGraph supervisor → Researcher/Analyst/Writer system on a local Ollama model, with independently compiled StateGraphs and code-level guardrails so routing stays reliable without a paid LLM API.
- Applied Math Mastery. I owned full-stack delivery: React + TypeScript (Vite) with a Go Fiber REST API, JWT auth, CORS, rate limiting, gamification (XP, streaks, leaderboards), and Vercel monorepo deployment. Live at appliedmathmastery.vercel.app, open source on GitHub.
- Relationhance. I built a monetized B2B/B2C SaaS with LLM integration and end-to-end Stripe billing on Go, MongoDB, and JWT, targeting the $250B+ edtech and workplace training market.
