Execution, not slide decks. → AI-Accelerated Delivery I ship with Claude Code, Cursor, and MCP Servers daily — making me 10x more productive than traditional developers.

𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞 Phase 1 → Discovery (Free) 20-min call. I understand your problem, users, and constraints. I tell you honestly if AI is the right solution — and if I'm the right fit. No pitch. Just clarity. Phase 2 → Architecture & Roadmap Before writing code, I map your highest-impact AI opportunities, prioritize by ROI, and deliver a clear plan with milestones. Phase 3 → Build & Ship Focused 1-3 week sprints. Working demos weekly — real software, not status reports. Every system reviewed for architecture, security, and scalability. Phase 4 → Launch & Support I don't vanish after delivery. 30-day post-launch support included. Monthly retainers available for ongoing development and AI optimization. 𝗡𝗘𝗫𝗧 𝗦𝗧𝗘𝗣 Send me a message with: 1. What you're building (or want to build) 2. Your timeline and budget 3. Where you're stuck I'll respond within 4 hours with a straight answer — whether I can help, a rough scope estimate, and 2-3 questions to sharpen the plan. No sales pitch. No generic template. Just an honest assessment from someone who's built this before.
