High-end SaaS & AI MVPs built in weeks.
Cover image for Role: Lead Product Architect &
Role: Lead Product Architect & AI Engineer Summary: I architected and built Highstory.ai (http://Highstory.ai) from the ground up—a fully autonomous AI marketing agency in a SaaS format. What I built: The "Magic" UX: Designed a frictionless user experience where the user simply inputs a URL, and the system automatically generates a complete, multi-channel marketing strategy. Complex AI Orchestration (Backend): Engineered a highly complex backend architecture integrating multi-provider APIs to power a swarm of ~20 specialized AI agents. These agents communicate and collaborate in real-time, replicating the workflow of a real-world marketing agency (Strategist, Copywriter, Video Editor, Data Analyst). Full-Stack Feature Delivery: * Built an "Autopilot" mode for 100% autonomous account growth. Engineered multi-format content generation: AI-generated text, carousels, and video posts. Developed a hybrid dashboard allowing users to seamlessly switch between AI generation and manual post drafting. Integrated real-time analytics to track strategy performance.

Role: Lead Product Architect What I built: I developed GEO Shaper, a high-end "Generative Engine Optimization" platform that allows brands to monitor, analyze, and influence how they are perceived by AI Search Engines and LLMs. It’s the next evolution of SEO for the AI era. The Command Center: Built a real-time intelligence dashboard tracking brand dominance and "Global AI Presence Scores" across 14+ major LLMs (Gemini, ChatGPT, Claude, Perplexity, etc.). Live AI Intercepts: Engineered a "listening" system that captures and analyzes real-time LLM outputs, extracting sources and sentiment with high confidence (85%+). Deep AEO Optimizer & Graph Booster: Developed tools to inject brand authority into AI knowledge graphs, ensuring the brand becomes the "preferred source" for high-intent queries. Prompt Engine & Intent Analytics: Built a module to identify "Top Converting Prompts"—the exact queries driving AI referral traffic—and optimize for them specifically. Sentiment Shield & Reputation Management: Integrated a system to monitor and neutralize negative AI hallucinations or bias against a brand in generative responses.

Cover image for Role: Lead AI Architect What I
Role: Lead AI Architect What I built: I engineered Jaeger, a next-generation B2B Growth OS designed to outperform traditional tools like Apollo or Lemlist by shifting from "static lists" to "live intent." The "Sentinel" Engine: Developed a high-speed scanner that monitors LinkedIn, Reddit, and G2 in real-time to detect active buying signals and pain points using advanced "Intent-Based Dorking." Autonomous Reasoning & Synthesis: Built a cognitive backend that doesn't just scrape data—it reasons. It analyzes a prospect's specific problem and synthesizes hyper-personalized assets (like custom SEO/UX audits) as a "Trojan Horse" for outreach. Surgical Outreach (Sniper Phase): Engineered a 100% autonomous cold outreach pipeline that delivers personalized emails and LinkedIn DMs with a 25% average reply rate (10x industry benchmark). Authority Building & Ghostwriting: Integrated a module that builds the user's LinkedIn authority through AI-driven content and engagement, ensuring the "Sniper" hits a warmed-up target. Fintech Model (Pay-per-Lead): Architected the platform to support a performance-based billing system, where users only pay for hyper-qualified leads.

Club Management OS (Back-Office): Built a dedicated dashboard for club owners to manage their facilities, track bookings, and oversee their business operations. Player Experience & Matchmaking: Developed a community-driven platform where players can organize matches, join games, chat and interact. Fintech & Split Payments: Integrated a complex payment architecture allowing for "Split Payments," enabling players to share costs seamlessly while ensuring clubs receive automated payouts. Data Scraping & Geolocation: Implemented a robust system to scrape, verify, and display thousands of sports clubs with real-time availability and mapping.
