What I Fix

Three data problems costing your team hours every week

Most teams aren't missing data — they're missing a clear view of it. Here's what I typically see when a new client reaches out, and what I build to fix it.

"We can't see our numbers clearly"

Revenue, sales, conversion, and department KPIs — all in one Power BI workspace that updates itself. No more copying into slides.

  • Power BI report design
  • DAX KPI measures
  • Mobile-friendly pages
View service details

"Our data is scattered everywhere"

APIs, Excel, CRM, databases — I pull it all into a single structured model so every dashboard draws from one reliable source.

  • Python ETL scripts
  • PostgreSQL / SQL modeling
  • Scheduled refresh logic
View service details

"We rebuild the same report every week"

Scheduled Python scripts, automatic data refreshes, and alert-ready outputs — so your team stops touching the report and starts reading it.

  • Excel cleanup workflows
  • API data extraction
  • Email-ready outputs

Why Clients Choose Me

Teams that tried agencies and junior devs come to me

I work directly with 2–3 clients at a time — no handoffs to a junior, no account managers between us. You get me on every call and in every file.

The work covers everything: data extraction, SQL modeling, dashboard design, scheduled refresh, and a full handover with documentation you can actually use.

My job isn't to impress you with a complex setup. It's to make your important numbers visible, trustworthy, and easy to act on — every day.

Proof of Work

Numbers from real projects, not a pitch deck

Every stat below came from work I delivered and tracked — specific clients, specific outcomes.

15 hours saved per week

One client went from manually building daily reports to a Python + Power BI pipeline that runs on its own. Every morning. Zero input needed.

50K+ records, zero manual work

Built incremental sync logic that pulls, deduplicates, and loads 50,000+ records daily into PostgreSQL. It just runs.

25% faster dashboards

Rewrote DAX and SQL models for a client whose reports took 40 seconds to load. Now under 8 seconds.

Repeat clients, every quarter

Most clients come back with a second project — full ETL setups, expanded dashboards, or new automation. The work earns the next engagement.
