I help businesses fix, automate, and modernize the technical systems that slow down revenue and operations: websites, DNS and hosting, APIs, CRM workflows, dashboards, internal tools, and AI-assisted processes. Clients usually bring me in when something important is stuck, messy, manual, or hard to explain. I can diagnose the issue, communicate clearly, and build the fix myself. Common projects I help with: - Website, DNS, hosting, migration, and deployment fixes - WordPress, WooCommerce, and custom website improvements - API integrations and data workflows - CRM automation for HubSpot, Salesforce, and custom systems - AI-assisted workflows for notes, follow-up, research, documents, and reporting - Internal tools, dashboards, and operational software - Full-stack implementation with React, .NET, Python, SQL, and related systems My background sits across software development, sales engineering, RevOps, consulting, analytics, and business operations. That means I am especially useful when the technical work needs to connect to a real business outcome: faster operations, cleaner handoffs, better reporting, stronger sales workflows, or fewer manual processes. Good fit if: - Something technical is blocking your team and you need it fixed - Your website, hosting, DNS, or migration has become painful - Your CRM or sales process has too much manual work - Your data is scattered across tools and needs to become useful - You want AI automation tied to real workflows, not hype - You need someone who can talk through the problem clearly and then build the solution If you message me, send the system or workflow you are trying to fix, what is currently broken or manual, and what a successful outcome would look like.

US-Based Principal Engineer | Zero Outsourcing | 25 Years in the Trenches I provide the technical certainty that only comes from longevity. With over 100 projects completed on Upwork and experience dating back to the earliest days of the web, I build robust backend architecture that works the first time. Current Featured Solution: Advanced Jobber & HubSpot Sync I recently developed a custom Python listener & PHp-based integration for the service industry that automates: Real-time Client Sync: (Create/Update) between HubSpot and Jobber. Job Lifecycle Automation: (Create/Update) via high-performance webhooks. If Zapier or native integrations are failing your workflow, I can build you a custom, resilient bridge. Core Expertise: Python & FastAPI: Modern, asynchronous, and strictly typed APIs. API Integration & ETL: REST, GraphQL, and legacy SOAP services. PHP & Backend Systems: Custom architecture, Laravel, and database optimization. Data Architecture: Custom SQL design and complex JSON transformations.

I translate business requirements into production-ready code that is documented and resilient.

Hi, I am a US-based Full-Stack AI Developer, Automation Expert and Technical Product Manager with 10 years of experience. I help founders, small business owners, and early-stage startups take the stress out of software development and automation.

I have experience building custom software/applications, managing a software project's roadmap or helping to finish up an existing project. I am also well versed in API integrations and have integrated with services such as Amazon, Etsy, Stripe, Plaid, Fibery, Airtable, Twilio and many more. In recent years, I’ve expanded my expertise to include AI-powered solutions — helping businesses integrate intelligent automation and machine learning into their workflows. From building custom GPT-based assistants to document data extraction pipelines and AI-enhanced customer service tools, I bring modern AI capabilities into production-ready applications. Some of the tools, frameworks, and languages I am skilled in: ● JavaScript - React, Node.js ● Python - Django/Flask, LangChain, OpenAI API ● REST API Development ● API Integration Development ● AI/ML: OpenAI (ChatGPT, Whisper, DALL·E), Hugging Face Transformers, Vector DBs (Pinecone, Weaviate) ● Business Automation Tools - Zapier, Make, n8n ● Databases: PostgreSQL / MySQL / SQLite / DynamoDB ● Deployment: AWS (including Lambda, S3, Bedrock), Google Cloud, DigitalOcean, Heroku ● Document AI & Automation: Google Document AI, AWS Textract, OCR, RAG pipelines ● Front-end AI Chat Integrations (custom chat UIs with GPT-based backends) I look forward to discussing the details of your project. Kind Regards, Ryan Morrison

I am a backend engineer from Helena, Montana with 12 years of experience and a BS in Computer Science from Purdue University. If I'm not writing code I'm either mountain biking or skiing. I am an expert in task automation, finite state systems, data processing, data modeling, migrations, and API integrations. I have worked on dozens of projects aimed at streamlining business processes, with a focus on integrating products and services both internal and external. Other than APIs and automation, I specialize in Asp.Net and back-end architectural design/programming, but I can take on a wide variety of projects, small start-up MVPs, micro-services, API integrations, complex data migrations, as well as larger projects that involve heavy architectural work. My skills include: • ASP.NET Core MVC/RazorPages/C# • Entity Framework + Core • MS SQL/Oracle/MySQL • API Integrations (REST APIs, SOAP, WCF, GraphQL, plus others.) • Automation • ETL and Data Integrations • Business Analysis/Project Management/Lead Development • Expert in CRMs Thanks for reading!
