I’ve spent over 15 years on the front lines of healthcare. I’ve personally felt where and how the system breaks, and how it impacts patients, their families, & our communities.

Now, I build AI infrastructure to fix those pain points. 🧵

@mbritton Not a dirty lens, there was lineup of planets Venus and Jupiter with the moon recently.

Started using deepseek-v4-pro and deepseek-v4-flash last week

I was nervous about API billing usage because before I'd only used free tiers and token subscriptions in the past...

But 232 million tokens cost $2.53 which isn't too bad!

Fixing vector DB bugs for healthcare AI: today's PRs to LanceDB (async operations), Weaviate (client validation) & Milvus (collection ops). Clinical RAG depends on reliable vector search — every bug fix matters. #HealthcareAI #DigitalHealth #OpenSource #VectorDB

[Raphael Malikian MBBS BSc(Hons) @rtmalikian]

Open-source contributions in healthcare AI aren't just about code — they're about building the infrastructure that will save lives. Every PR to a clinical NLP library or vector DB makes a difference. Find a repo, pick an issue, and ship a fix. #HealthcareAI #AIinMedicine #Digi...

🩺 Just submitted PR #3642 to @milvusio pymilvus — adding explicit positive-int validation for target_size in compact(). Bool & negative values now get clear error messages. #3169

#HealthcareAI #AIinMedicine #DigitalHealth #OpenSource

[Raphael Malikian MBBS BSc(Hons) @rtmalikian]

Submitted 3 vector DB fixes today: Weaviate NumPy array handling, Qdrant vector dimension validation, and Milvus sparse matrix compat.

Open-source contributions sharpen every aspect of engineering — debugging, design, and deep codebase reading.
