You will get a full audit of your spreadsheet, with every error found and fixed
Top Rated

Project details
Most spreadsheet errors are not obvious. The file opens, the totals look plausible, and the number has been wrong for months.
I audit the whole thing, formula by formula. Broken ranges that stopped growing when you added rows. Hard-coded numbers buried inside a formula where nobody looks. Rounding applied twice. Totals that silently skip rows. Lookups that return the wrong line when a cell is blank. Percentages taken off the wrong base.
You get a written report: every problem, the exact cell, what it does to your result, and what it should be. On the Standard and Advanced tiers I also give you the file back with the corrections applied, so you can compare before and after.
If the file is beyond repair I will tell you that plainly rather than patching it, and I will say what a rebuild would cost.
I use AI tooling in the audit, and I disclose it because Upwork requires it. It is why I can read every formula in a large workbook at a fixed price instead of sampling a few and hoping.
Send me the file and you will have a price and a date the same day. No calls needed.

CALCULATION SPREADSHEETS AND MODELS
Pricing models. Payroll and tax calculators. Commission and margin models. Monthly reporting packs. Operational models that have to reconcile against a published source, not against a guess.
What makes my work different is the verification. Every figure in what I deliver is reconciled line by line against the source you give me, and you receive the reconciliation log with the file. You do not have to trust me — you can check the work.
Most recent build: a US federal payroll withholding engine in Excel. 9 tabs, 912 formulas, reproducing 4,350 figures published by the IRS in Publication 15-T to the dollar, with a 4,375-line substantiation log naming the source, page and date of every number. I can send it to you.
EUROPEAN PORTUGUESE (PT-PT) QA, PROOFREADING AND TESTING
This is what I am doing right now, on ongoing contracts: linguistic QA and proofreading of PT deliverables, localization testing, and manual payment-function testing on mobile builds. Native PT-PT and near-native English, translation both ways.
Top Rated, 98% Job Success, 617 hours and 25 contracts on Upwork since 2019.
HOW I WORK
· Fixed price and a fixed delivery date, quoted the same day you describe the job
· Everything is asynchronous — no calls needed, and I answer messages within a few hours
· I use AI tooling in the build. That is exactly why every figure is reconciled against your source and why you get the log — it is what lets me quote a fixed price on work that would otherwise take a week
· Unlimited revisions within scope for 14 days after delivery
One thing I will always be straight about: I do not give tax, legal or financial advice. I build the calculation exactly as the source you name specifies, and show you the reconciliation so your own advisor can check it in minutes instead of hours.
Tell me what you need and you will have a price and a date the same day.
Steps for completing your project
After purchasing the project, send requirements so Telmo can start the project.
Delivery time starts when Telmo receives requirements from you.
Telmo works on your project following the steps below.
Revisions may occur after the delivery date.
I read every formula, not just the ones you flagged
Broken ranges, hard-coded numbers hiding inside formulas, rounding applied twice, totals that silently skip rows, and lookups that fail on blanks. You get each one listed with the cell reference and what it does to your result.
You get the report, and the file back working
On the Standard and Advanced tiers the corrections are applied for you, so you can compare the before and after side by side. If I find the file is beyond repair, I tell you so instead of patching it.
