I have done a lot of exciting things this year, but this is the first one that has made my heart race again.
I turned my old Lenovo ThinkPad X1 into a hypervisor running Proxmox. For those who do not know the term, think of it as a server that runs servers.
For the first time in a long while I spent more than 10 continuous hours on a hobby project and did not notice.
I went in thinking the install was the hard part. It was NOT!
The real learning was everything after: carving the disk into a root volume and a thin pool so VMs get snapshots for free, giving the host two network paths with wireless as the fallback, and building a NAT bridge so guests share the host's connection while a second isolated bridge stays walled off for a security lab.
Remote access was its own lesson. ZeroTier on the host got me in from anywhere, and the host became the jump box into every VM behind it. Then key-only SSH everywhere, no passwords left on.
The first VM is now a Debian box running Docker, hosting a staging environment for an ISP billing system and CRM I am building, with a Cloudflare Tunnel in front so nothing is exposed directly.
Next is an ACS for TR-069 for remote network router/ONU management, then the lab. Case study to follow.

After a long silence — Power BI has been consuming all my hours 🎯
Just wrapped Page 1 of a multi-page sales performance dashboard for a supermarket chain client. This is what I've been building quietly instead of posting 😅
The problem:
My client was tracking sales in scattered reports — no single source of truth for MOM (Month-over-Month) trends, store performance, or daily variations. Leadership had to hunt through multiple sheets to answer basic questions.
What we built:
A live Power BI dashboard that answers:
✓ Which stores are underperforming? (Rankings updated daily)
✓ How much did revenue grow last month? (MOM % at a glance)
✓ Are we hitting targets? (Real-time KPIs with trend indicators)
✓ Which products drive revenue? (Top 10 breakdown)
✓ How do weekdays vs weekends compare? (Day-over-Day trends)
The tech stack:
Data cleaned in Excel → Loaded to Power BI → Published online → Live slicers for filtering by date, store, category
Pages 2 & 3 in progress (Store Analysis + Returns Breakdown). But honestly? This work is the kind you don't post about until it's done. Now it is.
To anyone rebuilding their portfolio:
Real client work beats portfolio templates every single time. Even if you disappear from LinkedIn for 3 months, showing actual deliverables matters more than consistent posting.

Too many businesses try to build complex predictive AI models before their basic data pipelines are even functioning. You cannot skip the fundamentals.
The Data Hierarchy of Needs for scaling SMBs:
Level 1: Stable Collection (SQL) — Your database health and data pipelines. If your raw data is broken, everything built on top of it will fail.
Level 2: Data Governance (Python) — Enforcing uniform definitions, cleaning messy data, and ensuring total integrity.
Level 3: Automated BI (Power BI) — Moving away from manual spreadsheets to automated executive views and daily KPI tracking.
Level 4: Predictive Insights (AI / ML) — Churn models and forecasting. This only generates ROI if levels 1 through 3 are rock solid.
Stop wasting time on manual data entry and broken reports. If you are stuck at Level 1 or 2, I can help you scale up. Check out my Contra services to get your SQL pipelines automated and your Power BI dashboards built right the first time.
