𝐀𝐈 𝐂𝐄𝐎 (𝐀𝐈-𝐀𝐠𝐞𝐧𝐭𝐢𝐜 𝐑𝐀𝐆-𝐁𝐚𝐬𝐞𝐝 𝐂𝐨-𝐩𝐢𝐥𝐨𝐭 𝐟𝐨𝐫 𝐄𝐱𝐞𝐜𝐮𝐭𝐢𝐯𝐞𝐬): Built an agentic AI system that acts as a conversational co-pilot for company leadership, giving CEOs direct, natural-language access to company data, reports, and operational context without waiting on manual reporting cycles. React, LangChain, RAG, Pinecone, OpenAI/GPT-4, Agentic workflow orchestration Designed a multi-step agent architecture (not single-shot Q&A) capable of reasoning across multiple internal data sources - financials, operations, and business metrics - to answer complex executive-level questions in plain language. Built a retrieval layer over structured and unstructured company data so the agent could ground its answers in real, current information rather than generic model knowledge. Focused heavily on making the agent trustworthy for high-stakes decision-making: clear source grounding, guardrails against hallucinated answers, and an interface built for non-technical executive users. The client has continued expanding the platform's scope post-launch, adding new data sources and agent capabilities as adoption has grown internally. 𝟐. 𝐆𝐨𝐓𝐚𝐜𝐤𝐥𝐞 (𝐆𝐨𝐨𝐠𝐥𝐞-𝐁𝐚𝐜𝐤𝐞𝐝 𝐒𝐚𝐚𝐒 𝐏𝐥𝐚𝐭𝐟𝐨𝐫𝐦): Built a platform connecting business owners with expert advisors, serving 100k+ users a month. React, Next.js, TypeScript, GraphQL, Node.js, AWS Lambda, Amazon Cognito Integrated Stripe, Google Calendar, Office 365, and Squarespace for real-time scheduling and payments. AI-assisted advisor matching improved match relevance by 42%. Booking friction dropped by 40% after redesigning the scheduling workflow. Multi-tenant architecture with fully isolated environments for admins, advisors, and business owners. 𝟑. 𝐏𝐚𝐭𝐢𝐞𝐧𝐭 𝐉𝐨𝐮𝐫𝐧𝐞𝐲 (𝐀𝐈 𝐂𝐥𝐢𝐧𝐢𝐜𝐚𝐥 𝐀𝐬𝐬𝐢𝐬𝐭𝐚𝐧𝐭): Built an AI-powered diagnostic assistant now used by 500,000+ practitioners in Brazil. React, LangChain, RAG, Pinecone, OpenAI, GPT-4 Enabled AI-driven diagnostic insights from structured and unstructured clinical data. Built scalable vector search for rapid medical context retrieval. Privacy-first architecture compliant with local health data regulations.
