I offer a chatbot audit to provide strategy for improvement.

Hi, I'm Josh 👋 — a Silicon Valley engineer turned obsessed automation geek. I built the UI for a multi-million dollar IoT initiative in San Francisco for Meta. I’ve also modernized legacy government systems used daily by thousands of VA employees. And I scaled my DTC brand to over $1M in sales—all powered by high-ROI automations. The nerdy deep dive (if you're into that sort of thing): I build automation systems that save time, drive revenue, and scale like hell. From replacing tedious manual workflows to launching AI-driven chatbots, my goal is simple: create smart systems that deliver real leverage. Here’s what that looks like: - AI Assistants & Chatbots: Custom logic flows, dynamic knowledge bases (auto-updating as your content evolves), and trained AI that handles everything—from lead capture and appointment setting to fully automated customer support. - Lead gen machines: Automatically source, qualify, and follow up via email, SMS, or DMs using custom-built AI icebreakers. Book meetings while you sleep. - Content automation systems: Turn a single idea into blogs, YouTube scripts, social posts, images, and metadata—the entire content ecosystem automated. - Automated client & team onboarding: Payments, briefs, internal docs, CRM updates, and SOP delivery—all triggered and managed hands-free. - API-powered integrations: I've integrated nearly every major CRM and project management platform—from Salesforce and HubSpot to Airtable, ClickUp, Trello, and beyond. With custom APIs, we can connect virtually anything. Whether you're ready to 10x a marketing channel, streamline your operations, or finally escape Google Sheets purgatory, I'll build a solution that works today—and effortlessly scales tomorrow. Let’s build something efficient—and maybe even a little unfair. Looking forward to working together!

Already burned cash on '$50/hr AI experts'? 🟢 I like to do the opposite of what most do. They deliver headaches. I deliver Agents that (trully) work. 🔵 If your problem can be solved with LLMs—I can build it. As a PhD in Language Models with a business mindset I solve real-world problems for startups who can't afford to fail. If you're still reading this, chances are you're tired of agreeable people who say yes to everything without questioning, deliver low-quality demos that never reach production, and make you look like a clown in front of potential investors. I'm Alberto, and I operate at the intersection of NLP research, LLM Engineering, and startups. When you hire me, your LLM implementation is something you can confidently put in front of investors, customers, and users. To be upfront: I'm not the cheapest, but I pride myself on never wasting your resources. --- Here are the main AI services I offer: > Build LLM Workflows and Agents with any propietary frontier model (OpenAI, Anthropic, Google...), or open-source model (LLaMa, Deepseek, Mistral...) > Use your preferred tech stack: Langchain, Langgraph, Pyudantic AI, Vercel's AI SDK, Crew AI, Letta, OpenAI Agents SDK, LlamaIndex... For: > Turning your knowledge base or website texts into a ChatGPT-like bot or Agent. > Customize any LLM to fit your specific needs using techniques like few-shot learning, fine-tuning, or prompt engineering. > Building Agents for automating your business workflows. Why choose me? Proven delivery backed by foundational LLM expertise: 🟢 In the last 2 years I've made +$250k freelancing, helped clients raise hundreds of thousands in funding & sales through LLM Automations & Agentic Systems. 🟢 I'm the founder of Summiz(dot)ai, the worlds-most advanced AI solution for efficient learning and content consumption optimization. Before that: 🤖 Helped big companies customise Large Language Models (BERT, GPT-3...) to create text classifiers, Q&A, and chatbots for their data and task. 👨‍💻 As an LLM Engineer with nine years of experience, I have a deep understanding of data processing, MLOps and LLMOps. 📜 Ex-researcher with ten Q1 research papers in NLP within a well-known European Research Group. 🩺 Worked on international projects funded by billionaire European funds ($80B Horizon's 2020, $806.9B Next Generations), developing language models for medical data. 🎓 With a PhD in NLP, I have the academic background and expertise to conduct advanced research and implement any NLP technique. I've also worked as a developer and business consultant, allowing me to bridge the gap between Research, ML development, and Business. 💲 As an individual investor who likes to invest in startups, I regularly talk to CEOs and business owners. This has given me valuable insights into the inner workings of businesses, including market dynamics, growth strategies, sales tactics, and customer needs. --- So, what's next? I offer a 𝙛𝙧𝙚𝙚 𝙘𝙤𝙣𝙨𝙪𝙡𝙩𝙖𝙩𝙞𝙤𝙣 ($𝟴𝟬+ value) if your idea sounds promising — this call is essential to make sure we're a good fit before working together. Ready to talk? Just click on "𝙝𝙞𝙧𝙚 𝙣𝙤𝙬" and I'll get back to you right away. One last note: I only work with business owners or CTOs. If you're not the owner, I'll need to speak with them first. Cheers, Alberto P.S. — I've done most of my work outside Upwork (over $250k in the last two years), through referrals and inbound.
