I worked on the backend data layer for Cylinder Health - a specialized GI care platform that has now helped over 145,000 patients manage digestive conditions through clinician-backed, personalized care plans.

My piece of the stack: the clinical records layer and the EHR ingestion pipeline.

━━━ What "FHIR-compliant" actually means when you build it ━━━

FHIR (Fast Healthcare Interoperability Resources) is the standard that lets healthcare systems talk to each other. In theory it's clean. In practice, every EHR vendor - Epic, Athena, Cerner - sends you data in their own dialect of FHIR, with custom extensions, missing fields, and inconsistent date formats.

So the ingestion pipeline wasn't just "normalize JSON into Postgres." It was:

→ Model the core FHIR resources correctly: Patient, Observation, Condition, CarePlan - each with the right cardinality and relationships

→ Write normalization logic that could handle what real EHRs actually send, not what the spec says they should send

→ Output a PostgreSQL schema queryable by both the application layer (fast, indexed, relational) and the clinical team (human-readable, auditable, filterable by condition/patient/date)

━━━ Why this matters beyond healthcare ━━━

Any platform where multiple data sources feed a single operational layer - fintech aggregators, multi-ERP SaaS, IoT pipelines - hits the same problem: you don't control the upstream data quality, but downstream users expect consistency.

The FHIR normalization pattern translates directly.

Building something in healthtech, or dealing with messy multi-source data ingestion? Happy to talk through the architecture.

just made the oracle way smarter in heliora and it feels like having a real celestial copilot now.

it actually pays attention to whatever page you are on so when you are spinning the astrocartography globe it talks about your power places, planetary lines crossing cities, and what those locations might awaken in you instead of generic chart talk. you can ask it stuff right in context like what marrakech would mean for you or which lines are lighting up and it just gets it, and it does this in the 3d sky and all other modules.

Most people assume astrology software is just a chatbot wrapped around a birth chart. Heliora is something very different.

Under the hood is a dedicated astronomy engine deriving planetary positions from professional ephemeris data, a custom chart calculation system supporting multiple astrological frameworks, and a real-time 3D celestial visualization layer capable of rendering orbital relationships, transits, and aspect geometry as a living system rather than a static diagram.

What you're looking at here is not concept art. Every planetary position, aspect line, and celestial relationship is being calculated and rendered in real time. The goal was to make the mechanics of the sky visible. To take thousands of years of astronomical observation and compress it into an interface that feels immediate, interactive, and alive. The platform includes a full natal chart engine, interactive 2D wheel, live 3D planetarium, AI Oracle, celestial archive, transit tracking, event forecasting, cosmic pulse monitoring, global field mapping, soul frequency generation, chart analysis, referral systems, observatory node support, and extensive personalization controls.

Rather than forcing a single way of engaging with astrology, the entire experience is designed to be explored, customized, and adapted to the user's level of interest and expertise.

just shipped the 3d precision lab and it feels extra meaningful today. an astrologer doing a museum presentation on shifting perspectives of the andromeda constellation responded saying she needed better solar system software for mac that actually worked for serious fixed star and perspective work. we basically built this for people like her.

you can rotate zoom and scrub through centuries in full 3d while the precision lab underneath runs swiss ephemeris sub arcsecond calculations in real time. fixed stars, parans, multiple reference frames, toggleable aspect lines rendered in 3d space, the whole thing. feels like the tool we always wished existed when we were deep in the work.

just pushed a nice physics and visuals update to the 3d sky

we added accurate axial spin for all the planets. jupiter whipping around fast, venus basically frozen in its weird retrograde, earth doing its proper daily turn, everything based on real sidereal periods. feels so much more alive watching them actually rotate at their own pace.

cleaned up the belts too. main asteroid belt, trojans, centaurs and kuiper now drift at proper keplerian speeds. inner stuff moves noticeably faster than the outer zones. no more backwards physics.

galilean moons around jupiter got tuned with their real orbital periods and laplace resonance. they feel way more natural now.

also added the slow zoom out from earth that reveals the full milky way. its pretty special. you start close, it pulls back, and suddenly youre floating in deep space with everything in context.

on top of that i updated the colored celestial nodes. they now have procedural swirling plasma textures with marbled filament patterns, emissive glow from within, a translucent outer shell with additive blending, and a soft halo aura. they feel way more energetic and alive instead of just flat colored dots.

its the little things like this that make the sky actually feel like the real solar system while still staying dreamy. as above so below, even in the code.

anyone notice the difference when you go into immersive mode? or got a favorite planet or moon you like watching spin?

Most astrology apps give you a pastel-colored daily affirmation and call it a day.

Heliora gives you this.

A full cyberpunk command center for your soul. Real-time 3D living sky with actual Swiss Ephemeris + JPL-grade astronomy running under the hood, NOAA API for live dynamic astronomy dashboards. Hellenistic Time-Lord predictions based on your chart, Live planetary positions, chakra pulse synced to the Schumann resonance, soul frequency rituals, astrocartography power maps, brainwave meditation layers, and an Oracle that actually reads your entire chart instead of generic AI slop, which you can try for free.

This isn’t a wellness app.

It’s a goddamn spaceship cockpit for navigating the dynamic cosmos and your own psyche at the same time.

After complaints about performance speed from cold outreach testers, just enabled lite mode so that heavy three.js, NASA textures, oort clouds, and galilean moon rendering, external galaxies, do not throttle experience on other tabs.
