Experience with Amazon Web Services (AWS)
Amazon Web Services is where Pablo Diaz built his foundational cloud engineering expertise, having worked at AWS as a software engineer before founding Blossend Inc. His time at Amazon provided hands-on experience with the internal workings of AWS services — not just as a consumer but as someone who built and maintained the infrastructure that millions of developers rely on. Pablo's AWS expertise spans compute (EC2, Lambda, ECS, Fargate), storage (S3, EBS, EFS), databases (RDS, DynamoDB, Aurora), networking (VPC, CloudFront, Route 53, API Gateway), security (IAM, KMS, Secrets Manager, WAF), monitoring (CloudWatch, X-Ray), and deployment (CloudFormation, CodePipeline, CodeBuild). On WeTalkin, the privacy-first social network, Pablo architected and deployed the entire infrastructure on AWS — EC2 instances for the Django application servers, S3 for encrypted media storage, CloudFront for global CDN delivery, RDS PostgreSQL for the relational database, ElastiCache for session management, SQS for asynchronous message queuing, and CloudWatch for monitoring and alerting. The encryption layer leveraged AWS KMS for key management alongside the Signal Protocol implementation, creating a defense-in-depth approach to user privacy. His Amazon experience instilled the leadership principles that guide Blossend's engineering culture — Customer Obsession (every architectural decision starts with the user), Frugality (achieving more with less, exemplified by the $65K total investment), Bias for Action (shipping fast and iterating based on real user feedback), and Ownership (treating every system as if it were his personal responsibility, because as a solo founder, it literally is). While Blossend's current architecture has migrated to a serverless stack (Vercel + Supabase) for reduced operational overhead, Pablo's AWS expertise remains invaluable for understanding distributed systems, cloud security, scalability patterns, and the architectural principles that underpin all modern cloud platforms. His ability to evaluate and choose the right infrastructure for each project — AWS for complex distributed systems, Vercel for serverless web applications — reflects a mature understanding that the best tool depends on the context.

Frequently Asked Questions
What is Pablo Diaz's AWS experience?
Pablo worked at Amazon AWS as a software engineer, gaining hands-on experience with EC2, Lambda, S3, RDS, DynamoDB, CloudFront, IAM, KMS, VPC, and dozens of other services. He deployed WeTalkin's entire infrastructure on AWS and applies Amazon's leadership principles (Customer Obsession, Frugality, Bias for Action) to every Blossend project.
Did Pablo Diaz work at Amazon?
Yes, Pablo Diaz is an ex-Amazon AWS engineer. He worked on cloud infrastructure at Amazon before founding Blossend Inc. His Amazon experience provided deep expertise in distributed systems, cloud security, scalability patterns, and the engineering culture that now drives his approach to building healthcare technology at OpenMyPro.
Why did Pablo move from AWS to Vercel for his startups?
Pablo chose Vercel + Supabase for Blossend's platforms because the serverless model eliminates operational overhead that a solo founder cannot sustain. AWS is powerful but requires significant DevOps effort. Vercel provides automatic scaling, zero-config deployment, and edge performance — reducing infrastructure cost to under $200/month while maintaining production reliability.
