Pandas & cleanup
What it is
Messy files become one table with a grain you can name.
The pain
VLOOKUP across four workbooks until someone breaks a column.
You get
A scripted clean, documented columns, and an output the dashboard can trust.
Home / Python
Python analytics
Python analytics & data pipelines
Clean the feed once. Stop pasting it every Friday.
PeekGraph builds the Pandas wrangling, the API pull, and the job that runs without a laptop open — so Power BI and Tableau drink from a table that already makes sense.
Workstreams
What a Python engagement includes
Python Pandas, APIs, ETL, scheduled jobs, and clean feeds for Power BI and Tableau. Scope is named on the call — nothing is billed from this page.
API pulls & ETL
What it is
Systems talk. Nobody exports CSV by hand.
The pain
A portal download every Monday, renamed, then pasted.
You get
A pull, a transform, and a load into the place the report already reads.
Scheduled automation
What it is
The script runs when nobody is at the laptop.
The pain
A notebook that only works if someone remembers to hit Run.
You get
A job, a log, and a failure you hear about before the meeting does.
Dashboard feeds
What it is
Power BI and Tableau read a table Python already shaped.
The pain
The model is doing cleanup that belongs in the pipeline.
You get
A stable output table and a refresh that does not start with Excel.
Analysis notebooks
What it is
The one-off question, written so it can run again next quarter.
The pain
A file called final_v7 that nobody can rerun.
You get
A notebook with inputs, outputs, and a short note on what the number means.
Checks & handoff
What it is
Row counts, schema checks, and a path someone else can run.
The pain
It worked on one machine. Production is a surprise.
You get
A small test layer and a handoff that does not depend on one hero script.
Fit
Who this is for
Analysts
Python already exists. The script still only runs on one laptop.
Ops / finance
A feed that arrives before the meeting, not after it.
Dashboard owners
Power BI or Tableau is fine. The input is the problem.
Sample
A pipeline, not a notebook named final

Sample · Python
Refresh pipeline
Someone pastes a CSV every Friday → a scheduled job that feeds the dashboard. Demonstration data, not a client file.
FAQ
Python questions before a call
Does Python replace Power BI charts?
No. Python cleans and moves data. The dashboard stays the meeting view unless asked otherwise.
Can the job run in existing cloud?
Yes. The job is fit to what is already paid for. The call is where that is named.
How much does a Python pipeline cost?
A written range comes after the call. Nothing is billed from this page.
Can existing notebooks be used?
Yes. Most work starts with the script already on the laptop.
Is confidential company data used as a case study?
No. The sample on this page is a demonstration.
Does Python work run remotely with a US team?
Yes. The files stay with you at handoff.
