    I am an experienced Data Annotator in the field of Natural Language Processing using Reinforced RLHF (Reinforcement Learning from Human Feedback). My primary focus is on training and improving AI language models by generating prompts and desired responses for training data, performing quality checks on annotated data, and extracting relevant data for analysts. In addition, I prepare original, creative content to be used in the desired responses as well as various other tasks in accordance with project guidelines. I have also learned to use my prompting skills to create different personas for chatbots using pre-trained models. Before transitioning to the field of data annotation and NLP/RLHF, I spent 20 years working as a paralegal in Connecticut. In 2016, I decided to pursue my passion for petsitting, and I moved to California and started my own successful business. Recently, I decided that I wanted to explore the possibility of working remotely in conjunction with the petsitting. That's when I discovered data annotation and prompt/content creation working with NLP language models. I was immediately drawn to the field and found that my attention to detail and excellent communication skills are valuable assets in this line of work. Through my diverse background and experience, I bring a unique perspective and skill set to my work as a data trainer/annotator. I'm committed to delivering high-quality data that supports the development of accurate and effective AI language models.

    Top 1% Expert-Vetted Talent on Upwork. I don’t just understand what’s possible with AI — I define it. But AI is just one part of the puzzle. I help companies build bold, differentiated product strategies — from scratch or chaos — and turn them into minimum lovable products that are sticky, smart, and built to last. I'm Joshua Segeren — founder, builder, strategist, and hands-on engineer. I’ve spent 10+ years turning ideas into scalable, high-impact products — from launching Microsoft 365 AI features used by 50M+ users, to building two profitable tech startups solo (yes, I designed, built the MVPs, and got them to traction myself). What I Bring: - End-to-End Product Strategy: From zero to MVP and beyond — I’ll help you define what to build, why it matters, and how to make it win. - Product Surgery: Have something live or in development? I’ll rip it apart (and tell you what you need to hear) — product, strategy, plan, roadmap. Whatever’s holding you back, I’ll find it and help you fix it fast. - AI & Emerging Tech Depth: I’ve shipped AI products using LLMs, computer vision, NLP, and more. I know what’s real, what’s coming next, and what’s hype — and how to build. - Technical Strategy & Feasibility: I bridge business goals and technical realities — helping you scope roadmaps, validate ideas, align budgets, and build execution plans your team can actually deliver on. - Customer Experience Focus: I don’t stop at “viable” — I push for lovable. The goal is sticky, differentiated, and emotionally resonant products customers remember and come back to. Employment History: Founder (CEO/CTO) | ShopCierge.ai 2024 – Present I built ShopCierge to give every online store a superhuman sales and support rep. It’s a GPT-4-powered shopping assistant that guides customers through their buying journey — answering questions, recommending products, upselling, and overcoming objections — all in real time, 24/7. It doesn’t just cut support costs. It increases conversions and cart sizes automatically. No training. No scripts. Just results. Bootstrapped, profitable, live on the Shopify App Store with a 5-star rating and adoption across dozens of merchants worldwide. Founder (CEO/CTO) | Fluid.computer 2022 – Present Fluid lets people control software — apps, experiences, displays — using just their hands in mid-air. No hardware. No gimmicks. Just camera + computer vision. It’s the world’s first software-only motion interaction platform. Feels like sci-fi, runs on normal devices, and unlocks a whole new category of touchless, 3D, natural interfaces. We’re piloting it with retail and experiential partners who want to wow users and rethink how people interact with tech — without making them touch a thing. Senior Lead Product Manager | Microsoft 2016 – 2022 I started and built the AI Language Experiences team at Microsoft 365 — before “AI” was a thing anyone took seriously. I connected Microsoft Research, Azure AI, and product teams to deliver the first-ever AI-powered features inside Office. We reimagined how presentations and communication should work — launching Live Captions & Subtitles (accessibility by default) and AI-powered Translation (global collaboration by default). These features now serve 50M+ users daily across PowerPoint, Outlook, Teams, and more. From zero to shipped: I set the vision, convinced stakeholders, rallied engineers, and got AI into some of Microsoft’s most sacred products. Five years. Zero hype. Real AI, real impact. Client Outcomes: What Clients Get: Outcomes That Actually Matter My work spans startups, public/private market investors, and small businesses — each with different needs, but one goal: clarity and momentum. For investors, I provide deep insight into AI trends, product roadmaps, and feasibility — helping them place smarter bets, evaluate teams, and cut through hype. For founders and product teams, I help shape ideas into products that resonate. I’ve built new interfaces that make complex tools simple — like turning Openbox’s capital modeling software into something usable via natural language. Through my own ventures, I’ve helped dozens of businesses automate support, increase conversions, and stand out in crowded markets. Some of my work is private, but the outcomes speak: better strategy, faster execution, and products that stick. Let’s Talk If: - You’re starting fresh and want to build a smart, differentiated product from the ground up. - You have something live or in development — and need to fix, clarify, or refocus. - You’re interested in AI, but don’t know how to build something truly valuable with it. - You’re in a high-stakes moment and want serious product strategy firepower on your side. - You’ll get honest insight, fast momentum, and meaningful outcomes — not fluff. Let’s start with a 30-minute consult and see what we can build together!
