Hire the Best Twitter API Developers

Being Expert-Vetted means I have a proven track record of making your business idea real, I speak fluent API. My magic is being able to figure integrations between systems. Regard me as an API whisperer - if it has an API, I can get systems to talk. I specialise in crafting messaging mini-apps using WhatsApp Flows messaging using the Meta Cloud API, as well as a number of visual chat builder solutions like (Message) Bird, Twilio, InfoBip, Voiceflow, ManyChat, n8n. Sometimes data bridges need to be built between APIs, and for this I build micro services using Cloudflare Workers, Queues, R2, and Durable Objects. The real power of WhatsApp is realised when it is integrated 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.

I build things that actually work and deliver fast. Over the past few years I've built and shipped real products — not just freelance gigs, but full systems I personally use and maintain. That includes a complete inventory management system for an e-commerce brand (Shopify + Shiprocket integration, RTO tracking, courier scoring, fraud detection), an algorithmic trading bot running on live Indian markets, and an automated content posting pipeline. All Python, all production. My sweet spot is backend work and automation — REST APIs, custom Python scripts, database design, third-party integrations, AI-powered tools. If you need something connected, automated, or built from scratch, I can do it. I work fast, communicate clearly, and won't disappear mid-project. If something needs fixing after delivery, I'll fix it — no drama. What I can help with: Python scripting and automation REST API development and integrations Custom software and internal tools AI integrations (Claude, OpenAI Gemini) Database work PDF generation, data pipelines, web scraping If you have a problem and need it solved quickly, just message me.
