"Dr. Heller writes clearly and often lyrically, as well as humorously" wrote Edward Hallowell, M.D. on the cover of "Too Loud, Too Bright, Too Fast, Too Tight (HarperCollins, 2002)." I am a developmental psychologist and well published author of popular psychology books (HarperCollins, Wiley, Macmillan). These include a book on parenting, on healing anxiety and fear, on non-psychological causes of anxiety, and on sensory processing disorder. My books have been reviewed in Time magazine, Newsday, Psychology Today, the Washington Post, and articles written about them in Vogue, Cosmopolitan, and the Miami Herald among other publications. I have ghostwritten many memoirs and books on self-development. Having also written a novel and 4 screenplays, as well as children stories and poems, I can write in the fiction genre as well. I am good at organizing a book -- organization is the key to writing a good book -- and can write a book from start to finish or using the client's content. My writing style is economical, concise, clear and compelling with a touch of wit and humor and without fat and fluff. I have been writing professionally for close to 20 years and produce fast results, adhere to deadlines, and maintain excellent communication with my clients.

To be in business today, you need a successful, engaging, and authoritative website. But if customers don't find your website, you are likely losing out on some valuable people (and revenue too). The best websites subscribe to the EEAT principle - content should demonstrate experience, expertise, authority, and trust. I write people-first website content, such as blogs, articles, and landing page copy, that helps position your organization as experienced experts who are authorities in their space. The content I prepare for you will help you earn your customers' trust, establishing your company as an expert, so they keep coming back. The risks of poor copywriting and content on your website: 🔴 Increased bounce rates 🔴 Confusion about the products and services that you sell 🔴 A bad taste that you are a low-quality business, and customers won't trust you 🔴 A poor brand story Great content, on the other hand, can do the following: 🟢 Drive more traffic to your website 🟢 Help improve your search engine ranking results 🟢 Build a relationship with your audience 🟢 Make you stand out from your competition Here is what I can do for you: ✅ Create high-quality, authentic, and engaging content that your customers will want to read ✅ Maximize site traffic by creating SEO-optimized content, including keywords, H1, H2, H3 headers, backlinks, etc. ✅ Provide headline recommendations via HeadlineStudio to give your article better SEO value ✅ Help you improve your search engine rankings and boost your credibility So what's my process? To get started, do one of the following: ➡️ Request a 15-minute call via Upwork so that we can connect and I can better understand your needs ➡️ Send me an Upwork contract that clearly outlines your needs and outcomes ➡️ I will review your materials and provide you with any remaining questions ➡️ I'll get to work, developing an excellent piece that you will want to post to your website right away

I am a fashion stylist working across editorial styling, e-commerce product styling, and personal wardrobe consulting. My work combines creative direction, visual storytelling, and style psychology to create looks that feel both visually compelling and strategically aligned with the client’s goals. Personal Styling • Capsule wardrobe systems • Complete outfit creation for events, travel, and lifestyle • Wardrobe audits and restructuring • Body type and color analysis • Lookbooks with direct shopping links Editorial & Commercial Styling • Editorial styling for magazines, campaigns, and fashion shoots • E-commerce styling for product photography • Creative direction for fashion content and visual storytelling • Mood boards and concept development for photoshoots My background combines fashion styling and psychology, allowing me to approach clothing not only as aesthetics but also as visual communication. When building a look or wardrobe I analyze: • body proportions and silhouette balance • color harmony and skin tone interaction • fabric structure and movement on camera • the psychological impact of clothing on perception and confidence This approach ensures that every look works visually, strategically, and emotionally. I collaborate with brands, photographers, production teams, and private clients, helping translate ideas into clear visual identity — whether for a photoshoot, digital campaign, or a functional personal wardrobe. Deliverables • Styled outfits and wardrobe concepts • Editorial and photoshoot styling direction • Capsule wardrobe systems • Detailed PDF lookbooks with shopping links • Visual concept boards for shoots or campaigns • Styling consultation via Zoom

I design, build, and validate assessments, and I evaluate the AI tools that are starting to do the assessing. Most of my Upwork clients are companies building an assessment product or platform, and founders or HR teams who need an existing assessment validated, defended, or rebuilt. If you need a validation study, a custom test built (cognitive, personality, SJT), a scoring framework, or an expert read on whether an AI hiring tool measures what it claims, that is my lane. I'm an I/O psychologist (PhD) with 15 years in assessment. My work has been deployed millions of times across 30+ countries, for global brands (McDonald's, Coinbase, Coca-Cola) and for startups shipping their first product. At Coinbase I ran evaluations of AI hiring and assessment vendors: pressure-testing claims, running the analyses, and delivering plain-English go/no-go decisions. Recent projects: - Built and validated a situational judgment test (SJT) for a hiring platform - IRT and DIF analysis to optimize item banks - Scalable leadership assessments for executive coaching firms - AI hiring-tool evaluations and vendor claim reviews - Structured interview design and interviewer training - Commercialization support for assessment products sold to HR buyers What clients say: "Dave demonstrates an expert-level command over statistics and delivers results ahead of schedule. He is also quite adept at communicating, especially when translating technical content to a lay audience." (Jessica Brown, Ph.D., Amazon) "Across all of these engagements, Dave consistently and fluidly drew from his exceptionally deep level of statistical, psychometric and legal expertise to help devise solutions to demanding and challenging situations." (John Capman, Ph.D., Amazon) "Dave is reliable, responsive, and did an excellent job of completing requested contract work around assessment building and scoring for my hiring software... well received and shown promising results." (Clint Smith, CareerPlug) Services: - Custom assessment design and development - Validation studies and adverse impact analysis - Psychometrics: IRT, CAT, CFA, DIF, scoring frameworks - AI hiring tool evaluation (go, no-go, or what to test before you commit) - Structured interview systems and interviewer training - Expert review of assessment content and structure If you're building an assessment, fixing one, or deciding whether to trust one, let's talk.
