M.Sc. Strategic & Technology Management · Specialist in Quantitative Finance

Economics, strategy and capital markets.

Quantitative research, economic models, econometrics and financial analysis to interpret macroeconomic dynamics, find patterns, identify signals and build evidence applied to capital markets.

Method

Data describes. Method makes it understandable.

Every analysis begins with a specific question, defines the evidence required and states its limitations before reaching a conclusion.

My method combines economic and financial research with business intelligence, statistics and quantitative analysis. The work begins by framing the problem, identifying the relevant variables and actors, and developing a hypothesis about the mechanisms that may explain the observed outcome.

Data is integrated, cleaned and tested to detect trends, anomalies and regime shifts. A signal, however, is never interpreted in isolation. It is examined within its macroeconomic, productive, institutional and financial context, connecting policies and incentives with the real economy, expectations and market prices.

An insight becomes useful when it clarifies what changed, why it may have changed and under which conditions it could persist. Each conclusion is tested against alternative explanations and translated into scenarios, risks and concrete decision implications—without claiming more than the evidence can support.

Process

Eight steps from question to decision, grouped into three phases.

01

Question & framing

Frame the problem, identify the relevant variables and actors.

02

Hypothesis

Develop a hypothesis about the mechanisms that may explain the outcome.

03

Data integration

Integrate, clean and test the available data.

04

Detection

Trends, patterns, behaviors, anomalies and regime shifts.

05

Context

Macroeconomic, productive, institutional and financial — policies and incentives, the real economy, expectations and market prices.

06

Insight

What changed, why it may have changed, and under which conditions it could persist.

07

Validation

The conclusion is tested against alternative explanations.

  • Survives — continues to 08
  • Fails — returns to 03
08

Decision

Scenarios, risks and concrete decision implications — without claiming more than the evidence supports.

03 — Interactive model

Watch a small open economy respond when policy moves.

This model shows how government spending, taxes and the money supply set output, the interest rate and the exchange rate in a small economy open to world capital. The IS curve stands for the whole goods market — consumption, investment and government spending together, not spending alone; LM stands for the money market; BP marks the combinations of output and interest rate that would keep the external sector balanced. All three have their own slope, and all three move: the exchange rate is precisely the variable that adjusts until the three curves cross at exactly the same point.

IS — Investment-Saving
Represents equilibrium in the market for goods and services.
LM — Liquidity-Money
Represents equilibrium in the money market.
BP — Balance of Payments
Represents equilibrium in the external sector, where the current account and the capital account net to zero.

Taxes. Further right, lower taxes — a more expansionary stance.
Monetary stance Neutral

Money supply. Right = more money.

Output: arbitrary units, not a real currency. Exchange rate: index points vs. neutral, not a percentage · 0 = neutral, + depreciation, − appreciation.

Starting point: output of 648, interest rate of 2.92%. Move any of the three controls below and watch all three curves shift together.

Method · Closed-form Mundell-Fleming (linear IS/LM/BP, imperfect capital mobility, floating exchange rate, small open economy). The three curves are solved as one simultaneous system — the exchange rate is the variable that makes them cross at exactly one point, not a diagnostic computed after the fact. Parameters are illustrative, fixed for teaching the mechanism — not estimated from data, not a forecast of any real economy. Being linear, the model has no zero lower bound: at extreme slider settings the interest rate can read below what any real central bank has ever set (post-2008 policy rates only ever reached about −0.5% to −0.9%) — that range is a property of the algebra, not a claim about how real economies behave at the limit.

Trajectory

From econometric method to systems that carry it.

Each stage exists because the previous one hit a limit that could not be solved with more of the same.

  1. 01

    Economics and quantitative training

    Macroeconomic theory, econometrics and predictive modelling. The methodological base: what an estimator can and cannot claim, and where identification breaks.

    Method without data infrastructure does not reach a decision.

  2. 02

    Business Intelligence & analytics

    Analytical warehouses, ETL automation, star schemas and executive reporting — the layer that turns transactional records into a single source of truth.

    A reliable warehouse still does not tell you what to do.

  3. 03

    Financial analytics & capital markets

    Econometric method applied to portfolios and valuation: rate sensitivity, scenario work and cash flow under uncertainty.

    Analysis that lives in a notebook does not survive an organisation.

  4. 04

    Data-driven products and platforms

    Platforms that centralise the business picture — predictive analytics and dashboards operating as instruments, not decoration.
