    🧨As an Expert-Vetted Upworker, I have a proven track record of developing solutions and MVPs to make your business idea come alive with code, creative thinking, and an obsession about customer experience. Part of this magic is being able to wrangle integrations between systems. Regard me as an API whisperer - if it has an API, I’ll be able to figure out a way to get systems to talk. I specialise in crafting WhatsApp Bot messaging using the Meta Cloud API for conversations and Flows, as well as a number of visual chat builder solutions like (Message) Bird, Twilio, InfoBip, Voiceflow, ManyChat, Dialogflow. Sometimes data bridges need to be built between APIs, and for this I build micro services in Cloudflare Workers. The real power of this channel is realised when I integrate it into your systems, workflows, and CRMs, as well as tapping into external services (like ChatGPT’s OpenAI) via APIs. Other API integrations I’ve done include Stripe, Monday.com, Knack, Airtable, Google Sheets, OneDrive, Hubspot to name a few. 🦸‍♂️ SUPERPOWER Articulating, framing, and presenting complex ideas after deep research. 🧰 SKILLS TOOLBOX If you need very specific skills for a defined period: • WhatsApp API bot strategy, service design, development • Customising data transformations using Cloudflare Workers where Make/Zapier can't do the job • API expert: Stripe / Monday.com / Knack / Airtable / Zoho /Google Sheets / OpenAI / Amadeus • MVPs and proof-of-concept development • UX reviews and audits • User Journey + CX Analytics • Optimisation & UX A/B Testing + CRO • Pitch research and technical leadership • Analytics deep-dives & GA4/BigQuery/GTM • App flow and user research • AWS S3/Lambda/EC2 & Cloudflare Workers • Business ⇄ Technical Communicator • Can both think and do digital: from code and Figma prototypes, to developing and articulating digital strategy for C-Suite and Technical audiences. • Was a core member of the global Publicis Groupe Creative Technologists team 💚 CLIENTS LOVE ME “I am consistently amazed by Simon's exceptional ability to tackle new initiatives with a fresh perspective.
