Kleivin Gjuzi

Finance Analyst & ControllerVienna, Austria

Finance and management trained analyst combining FP&A, business analytics, and hands on AI automation.

There is a line I want to finish first

I always like the full picture, or the context.

“A jack of all trades is a master of none,but oftentimes better than a master of one.”

Most people stop at the comma. The rest of the line is the part I have built a career on: enough finance to hold the numbers, enough management to run the thing, enough marketing to fill it, and enough engineering to automate it.


Skills

One tree, four branches.

Finance is the trunk. Each branch carries its skills and the projects that grew on it, with room for the next one.

FY2026E and FY2027E are forecasts in the base scenario and include Erste Bank Polska.

1,975EUR millionNet profit attributable to owners in the first half of 2026, up 18.6% on a year earlier.
8.3%Growth in operating income excluding Poland in the first half of 2026, against 3.4% for costs.
4,402EUR millionNet profit forecast for 2027 in the base scenario. The downside scenario gives 2,897.
170EUR millionLower 2027 net profit for every 10 basis points of extra risk cost.
Findings
  1. 1Net interest income drives the business, and the Polish acquisition adds scale more than profit for owners.
  2. 2Like for like, income is growing faster than costs again, after a negative year in 2025.
  3. 3Reported risk costs nearly tripled, but the underlying level is close to last year's.
  4. 4One-offs and banking levies matter below the operating result.
  5. 5The base forecast is in line with the company's direction, and the plan comparison shows where the first half differed.
Recommendations
  1. 1Report every key figure on two bases until the comparatives include Poland: as reported, and like for like.
  2. 2Track the second half cost run rate against the full year outlook each month, by cost type, with integration costs shown separately.
  3. 3Set early warning thresholds for risk costs and banking levies, the two largest profit risks outside management's direct control.
How it was checked

Ten sheets and 49 built in checks, all passing. An independent Python model recomputes 725 cells and matches Excel. Eleven official sources, each with its page reference.

Public information only, research cut off 11 October 2026. Not affiliated with Erste Group Bank AG. Forecasts are illustrative, not company guidance and not investment advice.

FY2027E is a forecast in the base scenario. Free cash flow is a non-GAAP measure.

331.8USD billionRevenue in fiscal year 2026, up 17.8%. Intelligent Cloud supplied 11.2 points of that growth.
67.0USD billionFree cash flow in fiscal year 2026, down from 74.1 two years earlier while cash capex rose to 115.9.
23.0USD billionFree cash flow forecast for fiscal year 2027 in the base scenario, with cash capex of 184.
6.0%Revenue growth at which 2027 free cash flow falls to zero. The base scenario assumes 16.5%.
Findings
  1. 1Intelligent Cloud drives the growth, and More Personal Computing is shrinking.
  2. 2Operating leverage has more than offset a falling gross margin, so far.
  3. 3Less cash remains after investment each year.
  4. 4In the 2027 base case growth continues and free cash flow shrinks to about a third.
  5. 5An illustrative scenario shows what extra investment would have to earn, and where the forecast risk sits.
Recommendations
  1. 1Track investment and cash on three lines every month: cash capex, capex including finance leases, and free cash flow after lease principal.
  2. 2Release incremental capex in stages against a stated hurdle, and keep the short lived two thirds of spending flexible.
  3. 3Protect the operating margin through operating expense discipline and unit cost efficiency, with depreciation and amortisation as a tracked line.
How it was checked

Twelve sheets and 55 built in checks, all passing. An independent recalculation in Python matches Excel on 1,035 cells. Seventeen official sources, and 77 hand keyed figures traced back to the 10-K and the earnings call.

Year to date, January to September 2026. Synthetic data for a fictional company.

43,807journal linesIn 16,698 journals over 24 months, with a budget by cost centre and account.
28.8%Shortfall of the net result against budget for the year to date. About two thirds of the gap is cost, not revenue.
79exceptionsFound by 11 automated close checks. The month being closed has one blocker and three must fix items.
62testsAutomated tests, all passing, that reconcile every report total back to the source postings.
Findings
  1. 1The result is 28.8% below budget, and the gap is mainly cost, not revenue.
  2. 2Building Systems is the weak department, and Industrial Components makes up for part of it.
  3. 3Four cost items explain the overspend, and two of them were never budgeted.
  4. 45% of shared costs cannot be allocated, and the department ranking depends on the allocation key.
  5. 5The close checks found 79 exceptions, and the month being closed has one blocker and three must fix items.
Recommendations
  1. 1Do not close the month until the blocker and the must fix items are cleared, and make the close cockpit a formal gate.
  2. 2Give the two unbudgeted cost blocks an owner, a supplementary budget and an allocation driver, then reforecast the year.
  3. 3Review Building Systems with its management, and judge the department on its contribution before allocation.
How it was checked

Ten tables and 22 views in DuckDB, with 17 analysis queries. 62 automated tests, all passing, reconcile every report total to the source postings and check the 11 close checks against an answer key of 79 planted exceptions.

Everything here is synthetic. Alpenkante Systemtechnik GmbH is a fictional company and every figure comes from a seeded generator. The findings show the method and say nothing about any real business.

Over 24 months. Contribution margin is gross margin less modelled service costs. Synthetic data for a fictional company.

60.1daysCash conversion cycle: 72.0 days of sales outstanding plus 45.3 of inventory, less 57.2 of payables.
30.5%Share of receivables past their due date. Seven customers hold 85.3% of the overdue amount.
17.5%Share of stock that has not been sold for at least 180 days.
127testsAutomated tests, all passing, covering invoices, credit notes, payments, open balances, stock and report totals.
Findings
  1. 1Profit and cash differ by the change in working capital.
  2. 2The largest customers earn the thinnest margins.
  3. 330.5% of receivables are overdue, and seven accounts hold most of it.
  4. 417.5% of stock has not moved for six months.
  5. 5The cash conversion cycle is about two months.
Recommendations
  1. 1Run collection by priority list: a weekly follow up of the seven class A accounts together with sales, and clear the old remainders.
  2. 2Review prices and discounts for power tools with key accounts: a floor above standard cost, and discounts linked to payment behaviour.
  3. 3Stop reordering the four products without demand, agree returns or a sell off, and require approval for purchases above a set number of months of demand.
How it was checked

Fifteen tables and 15 views in DuckDB, with 16 analysis queries. 127 automated tests, all passing. Child tables are aggregated to invoice grain before they are joined, so no total can be inflated by a one to many join.

Everything here is synthetic. Tauernquell Industriebedarf GmbH is a fictional distributor and every figure comes from a seeded generator. Tax treatment is simplified, and the findings say nothing about any real business.

Away from the desk

The analytical half is only half.

Everything below competes for the same evenings, and most of it ends up feeding the work anyway.

Composing

Self taught at the piano, and producing since I was sixteen. Film score and neoclassical mostly, with a lo-fi and jazz side to it.

Photography

Landscape and travel, taken between the Albanian coast and Vienna. Some of it was shown at the Art Gallery of Durrës.

Hiking and the outdoors

A year of running a campsite will do that to you. Hiking is still the fastest way I know to put a spreadsheet down.

Drawing

A featured artist while still at school. It is where the eye for composition came from, and it never quite left.

Swimming

Growing up on the coast makes this less of a hobby and more of a default setting. The closest thing I have to a reset button.

Volleyball

School team, and still the sport I will drop an evening's plans for. The one hobby with no keyboard involved.


Contact

Looking for the desk where this fits.

Based in Vienna, open to FP&A, controlling, business analytics, and FinTech. On site or hybrid, happy either way.
