8+ years building large-scale frontend platforms and secure authentication systems in production at enterprise scale (Angular, React, Vue). Alongside my day-to-day work, I build a portfolio of independent developer tools and AI-driven products:
- 🔭 Building SigTrace — a runtime signal-tracing and debugging platform for Angular Signals, Vue, and SolidJS.
- 🏗️ Building Graphist — a multi-agent software architecture intelligence platform (local-first AST analysis, live C4 diagram generation).
- 🌍 Building Aivygo — an AI-powered travel marketplace connecting travelers with local guides and experiences.
- 📝 Building PromptGitHub — a Git-inspired collaboration and version-control platform for LLM prompts.
- 💬 Ask me about: Angular, React, Vue, frontend performance, build tooling (Vite/AST instrumentation), multi-agent AI systems, and authentication systems (MFA/SSO) at scale.
- 🌱 Currently exploring: AI-assisted developer tooling, local-first LLM inference, and agentic engineering workflows.
SigTrace — Signal Lifecycle Tracer & Runtime Debugger
Visualize, trace, and debug reactive signal graphs in real time, directly inside VS Code — zero refactoring required.
- Build-time AST instrumentation (Vite plugin) that rewrites
signal(),computed(), andeffect()calls with no source changes. - WebSocket telemetry server + VS Code/JetBrains DevTools extension for live signal graphs, causal timelines, and diagnostics.
- Detects circular invalidation loops, computation hotspots, and dead reactive state.
- Framework support: Angular Signals, SolidJS (Vue 3 in progress).
Private repository (available on request). A multi-agent "Council of Agents" (Architect, Security, Logic) built on LangGraph that performs semantic analysis on every commit — with local-first AST parsing (Tree-sitter, no code leaves the machine), real-time Mermaid C4 diagram generation, and a FastAPI/Python backend paired with a Next.js 15 dashboard.
Private repository (available on request). A Git-inspired platform for versioning and reviewing LLM prompts: protected branches, optimistic-concurrency-controlled commits, pull-request diffing, inline review comments, and a 1–5 quality-scoring system. FastAPI backend, React/Vite/TypeScript frontend, PostgreSQL.
Aivygo — AI-Powered Travel Marketplace
A full-stack marketplace connecting travelers with local guides and experiences — discovery, host onboarding, booking, and an AI trip planner. Next.js 14 (App Router), Express/TypeScript, PostgreSQL + Prisma, Redis, Socket.IO. Built through a structured 6-role AI-agent development workflow (Founder → Product Owner → Product Manager → Lead Developer → Developer → QA).
- TripPlannerTool — constraint-based multi-day itinerary optimization engine (budget, pace, interests, scoring), extracted from Aivygo's trip-planning algorithm.
- ACIP (Automated Creative Intelligence Platform) — autonomous multi-agent pipeline that discovers new SaaS launches, records UI walkthroughs via Playwright, and generates/publishes video tutorials using local LLM/TTS/STT inference (Ollama, Kokoro, Whisper).
- Dependabot Security-Debt Agent — scheduled GitHub Action that triages Dependabot alerts, batches fixes into PRs, updates existing security PRs instead of duplicating them, and syncs with the default branch before pushing.
Developer Tooling:
— Vite plugin development, AST instrumentation (Tree-sitter), WebSockets, VS Code Extension API
AI & Backend Platforms:
— multi-agent orchestration, Playwright browser automation, local LLM inference (Ollama)
