Got the #LLM semantic to structural matching working. Testing with local #AI #olama . 4b models take 2 mins and not consistent and a little 1B is more accurate and takes 5 seconds! Need to investigate a rag vector filter upstream.

Implementing my own #dos measures for public forms. Honeypots and rate limiting. Any “free” or cheap custom form services will get you price wise if you actually expect any volume on your site.

#AWS apprunner does not play nice with godaddy dns for custom domain validations. Their new two step breaks with underscores in the DNS on godaddy. Forced to use route53.

[Sean O'Connor @sean_e_oconnor]

Finding that small 1B #llm hallucinates less than a 4B for semantic to structural matching. Using #AWS and #bedrock now for my new #saas project.

Using #AWS #kiro to dockerize my apps with specific requirements. It creates scripts, docs, and mult env configs, and deployment YAML. I don’t want to be a docker expert. It’s a breeze.

It energizes me being a #fullstack dev. #react and #ui one minute and #agentic #ai agents in python the next. Throw in C#, serverless cloud services, APIs, infrastructure, and deployment packages. I can build anything.

[Sean O'Connor @sean_e_oconnor]

So many take the easy route because of speed or simplicity. Like #vibecoding push deploy. This leads to vendor lock in and high costs when you scale. Write in a way to make the switch between platforms or services an easier lift. #coding #solopreneur

[Sean O'Connor @sean_e_oconnor]

Using #olama is great to develop local #ai #agents and proof out concepts without needing cloud #llm if your hardware supports it.

Starting a new SaaS project:
Patterns:
• Natural-language ingestion → structured data
• Context tagging + embeddings for signal enrichment
• Explainable scoring/rules engine
• Personalized weighting with ML evolution
• LLM-assisted reflection + feedback loops

Trying #AWS #kiro for #AI coding some new projects. Using requirements, design, and implementation task documents. Dials in unit test, integration tests, and more.. spec driven development.

Google just released a python library for data extraction!

LangExtract is a python library that extracts structured information from unstructured text documents with precise source grounding and interactive visualization.

Asking #AI to help write a job posting for an IT admin, I appreciate it’s incorporation of #devspeak and snarkiness..

[Sean O'Connor @sean_e_oconnor]

Saw a demo of the new #AWS Kiro. This is really a #Cursor killer. Develop #AI agents and docs with #vibecoding . Can’t wait.

Integrating #AWS Athena with our #DotNet web apps to build a bridge to our data lakes.

[Sean O'Connor @sean_e_oconnor]

Working with #AWS CDK to build stacks using #lambda functions from Images. Can't escape the custom #docker images for Lambdas with unique dependencies not out of the box.....

[Sean O'Connor @sean_e_oconnor]

Excited to start building cross platform apps with .Net MAUI now that it's in GA.

[Sean O'Connor @sean_e_oconnor]

Building CI/CD code pipelines with the #AWS CDK. So much easier to synthesize the AWS CloudFormation templates here with the Lambdas in the same solution. #DevOps
