A Power BI financial dashboard for healthcare finance teams connects EHR billing exports, the general ledger, and payer contract tables into a unified model, then applies row-level security so each cost-center owner sees only their data. A well-structured build takes four to six weeks and gives CFOs, finance directors, and department heads real-time visibility into revenue cycle performance, operating margin, and budget variance. Key Takeaways Connect EHR billing data, your GL, and payer contract tables through Power Query dataflows before building any visuals. Five essential views: revenue cycle summary, operating expense by department, budget variance heat map, payer mix analysis, and 90-day cash flow runway. Row-level security (RLS) scopes each department head's view to their own cost-center data without requiring separate reports. Scheduled dataset refreshes and Power Automate flows cut monthly reporting cycle time from days to hours. HIPAA alignment requires sensitivity labels, private links, and audit logging in addition to RLS - security roles alone are not sufficient. What Makes Healthcare Financial Dashboards Different from Standard Finance Dashboards? Healthcare finance operates under constraints that most corporate FP&A teams never encounter. Payer mix directly affects recognized revenue. Cost centers map to clinical departments spanning multiple facilities. And every data movement may touch protected health information (PHI) , which means the data architecture must satisfy HIPAA even when the dashboard itself shows only aggregated financial figures. According to Market Research Future (2025), the Healthcare Financial Analytics Market is projected to grow at an 8.58% CAGR from 2025 to 2035 , driven by value-based care adoption, regulatory changes, and demand for real-time decision support. Most healthcare organizations still export Excel files from their EHR and reconcile them manually against the general ledger. Power BI closes that gap - but only if the

> TL;DR — I run four different domains off one Next.js codebase: a marketing site at pagestrike.com , an authenticated app at app.pagestrike.com, a public publishing domain at pagestrike.app, and customer-owned domains. The trick isn't deploying four apps — it's a single proxy.ts that reads the host and rewrites/redirects/passes-through per-request. This post walks through why I chose this shape, the parts I got wrong, and the cookie-domain trick that makes it all stick. Stack: Next.js 16 App Router , Supabase , Vercel , one proxy.ts file (~370 lines). This is the second post in my build-in-public series on PageStrike . Last week I wrote about the 6-CTA architecture — modeling conversion intent as a discriminated union so one launch could be a checkout, a COD form, or a calendar booking. This post is about a different primitive: modeling host as routing context so one codebase can serve four very different audiences. Why four domains, not one Most SaaS apps live at one domain — say myapp.com with /dashboard under it. That works until you grow into edge cases that don't fit: Marketing pages get spammed by your own dashboard headers. Your marketing nav says "Sign in / Pricing / Blog". Your dashboard nav says "Launches / Contacts / Settings". You either A/B them with conditional logic everywhere or you live with the noise. Public user-generated pages share your domain reputation. When a customer publishes a landing page at myapp.com/p/[slug] , every spammy LP from a free-tier user drags down myapp.com 's sender reputation, search trust, and ad-account standing. Google and Meta penalize the host, not the path. Custom domains don't route cleanly. A customer who buys acmewidgets.com and points it at your app expects their LP at acmewidgets.com/ — not myapp.com/p/acme-widgets . You need a rewrite that's transparent to the visitor, doesn't 404 on _next/static/* , and survives RSC prefetches. I split PageStrike — a free AI landing page builder — across four hosts to solve al

I pondered the other day what's next for Microsoft's Surface PC lineup, and it looks like we're about to find out. Windows and Surface chief Pavan Davuluri has just teased "something new is coming for developers," complete with a mysterious image of what looks like a curved display edge. Davuluri notes that whatever is coming […]

In Part 14 , I finished HMAC webhook signing. The backend was complete — JWT auth, PostgreSQL, Redis caching, rate limiting, circuit breaker, worker pool, webhook delivery, migrations, Docker. All running locally. But "runs on my machine" isn't a portfolio project. It's a homework assignment. Time to ship it. The Stack Being Deployed Go backend — ~15MB Docker image (multi-stage build, CGO_ENABLED=0) PostgreSQL 16 — with golang-migrate running schema migrations on startup Redis — for caching, rate limiting, and refresh token storage Oracle Cloud Free Tier — 1GB RAM, 45GB disk, already provisioned Everything wired together with docker-compose.yml . One command to start the entire stack. Step 1: The VM Was Fine, Actually I was worried about the free tier specs. Turned out the "1GB" in the tier name refers to RAM, not disk. The actual disk is 45GB — plenty. free -h # 954MB RAM, 552MB available df -h # 45GB disk, 41GB free The real constraint: no swap . Go's compiler is memory-hungry. Without swap, building the Docker image on the VM would exhaust RAM and kill the process. More on this in a moment. Step 2: Install Docker curl -fsSL https://get.docker.com | sudo sh sudo usermod -aG docker ubuntu newgrp docker The official install script handles everything — Docker Engine, containerd, Docker Compose plugin. One command, done. Step 3: Clone the Repo The repo is private. Created a fine-grained GitHub personal access token with Contents: Read-only permission. Used it to clone: git clone https://TOKEN@github.com/absep98/Go_learn.git Security note: never paste tokens in chat, email, or anywhere visible. Type them directly into the terminal. Tokens in chat history are compromised tokens. Step 4: Create the .env File The .env from my local machine needed two changes for Docker: # LOCAL (wrong for Docker): DB_HOST = localhost REDIS_HOST = localhost # DOCKER (correct): DB_HOST = postgres # ← service name in docker-compose.yml REDIS_HOST = redis # ← service name in docker-compose.ym
