Joshua L.

Full stack web dev, automation, and OpenAI & Anthropic Expert.

About Me I’m a senior technologist with more than a decade of experience delivering complex software systems that connect business goals to technical execution. As a Senior Technical Program Manager at Amazon, I’ve led large-scale AI, automation, and cloud initiatives powering products used by millions. My background spans both business and engineering. I started my career managing web projects for agencies in San Diego, where I learned how to ship quality products quickly. Over time I transitioned into development, completing the Full Stack Codecademy path and joining an agency as a hands-on developer. Since then I’ve built and scaled intelligent, serverless applications across healthcare, legal tech, and SaaS—always with a focus on measurable impact. Recent Work Built AI-driven communication systems using Twilio, AWS Lambda, and OpenAI for context-aware messaging and automated conversations. Delivered HIPAA-compliant healthcare integrations with AWS and Auth0 for secure patient engagement. Architected a case-management SaaS platform with AI-based document drafting and automated messaging. Designed custom AI training pipelines that tailor tone and language per client using OpenAI’s API. Implemented serverless architectures leveraging AWS, Cloudflare, and Zapier to achieve scale with minimal maintenance. Core Expertise OpenAI (ChatGPT API, embeddings, fine-tuning, prompt engineering) Twilio (SMS, Voice, Video, Chat, Studio) AWS (Lambda, API Gateway, DynamoDB, S3, SES, CloudWatch) Auth0 & Identity Management Cloudflare Zapier & Workflow Automation Google Workspace API Stripe Payments HIPAA-Compliant System Design Also familiar with Slack automation, Azure, GitHub/GitLab administration, Linux servers, and CMS platforms such as WIX and WordPress. Why Clients Work With Me I combine the strategic perspective of an Amazon-trained program manager with the precision of a senior engineer. I’ve delivered AI and automation platforms processing thousands of interactions per hour, built SaaS products from concept to launch, and helped organizations modernize operations while maintaining strict compliance. Clients hire me because I think like a CTO, code like a senior developer, and execute with the reliability of someone who has led large-scale programs at one of the world’s most demanding tech companies. If you need someone who can take ownership from architecture through delivery and make sure the product actually works, let’s talk.
