builds things.

Pharma field-rep CRM with a ReAct-style LangGraph agent powering a conversational interaction-logging interface alongside a structured form path.

• LangGraph agent with 5 scoped tools: log, edit, summarise voice notes, suggest follow-ups, resolve materials
• Structured form path bypasses the LLM entirely — agent invoked only for free-text chat
• Defensive type coercion and graceful error returns to handle LLM tool-argument inconsistencies
• Diagnosed and recovered from a mid-build model deprecation (Groq decommissioned the assigned default model) by substituting the specified fallback with no architecture changes

Production-ready reference architecture for secure Android authentication — not a tutorial, a strict engineering blueprint.

• Jetpack Compose UI with Hilt DI — clean separation of auth logic from presentation layer
• Interface-driven MVVM design for full testability and swap-ability of auth providers
• Async session persistence via DataStore — handles expiry, credential failures, and network edge cases

Real-time collaborative task board with full authentication, live sync across users, and complete audit trail — production deployed on Vercel + Render.

• Real-time board sync via Socket.io rooms — changes reflect instantly across all connected users
• JWT auth with bcrypt (12 rounds) + UUID-based board invite system for secure multi-user collaboration
• Card activity logging on every change + soft delete pattern throughout with Drizzle ORM type-safe schema
