Working tools for advertising and product data

If the team already spends money on acquisition, but reports are assembled manually, events do not reconcile, attribution is unclear, or research lives in spreadsheets, I build the first operational layer in 2-4 weeks: reporting, event QA, alerts, LLM-assisted research, a data layer, or an internal interface.

My scope is data, events, integrations, reporting, research, and operational tools around growth and product workflows. Campaign management and media buying remain with your team or agency.

Who this page is for

When it makes sense to get in touch.

When a team already spends money on acquisition, the bottleneck is often not campaign setup but the data around it. These are six common situations where a focused engineering phase can help.

01

The numbers do not reconcile

Ad platforms, MMPs, product analytics, and internal reports show different results, and the team cannot tell which source to trust.

02

Reporting is assembled manually

The team spends hours exporting data, updating spreadsheets, taking screenshots, and preparing recurring summaries for marketing, product, or management.

03

Events and postbacks need QA

Events, postbacks, attribution windows, sources, UTM parameters, SKAN/MMP data, and discrepancies between systems need to be checked.

04

Traffic quality is difficult to monitor

The team needs explicit rules, alerts, and sanity checks to notice anomalies, suspicious sources, missing data, and abrupt changes.

05

Research is still manual

Partners, competitors, segments, creatives, product hypotheses, or market signals are found manually and updated irregularly.

06

Off-the-shelf tools do not cover the workflow

The tools exist, but the team still needs a custom layer for APIs, exports, rules, reporting, alerts, and an operational interface.

What can be built in the first sprint.

One sprint, one operational result around advertising and product data: a report, event QA, alerts, a research tool, a data layer, or an internal interface.

01 Report

Consolidated report for a growth or product team

One recurring report across ad platforms, MMP data, product events, spreadsheets, and internal sources, without rebuilding it manually every week.

Engagement formats.

We usually start with a focused assessment, then move to a sprint or a larger phase. Support is for tools already in use, not an undefined development subscription.

Format · 01

Growth/Data assessment

Review events, data sources, reporting, manual work, and risk points. The output is a map of the problem, a sensible first sprint result, and a recommended next step.

Budgetfrom $500

If a Working Tool Sprint starts within 14 days, the assessment fee can be credited toward the sprint.

Format · 03

Larger delivery phase

For work that does not fit one sprint: several data sources, teams, platforms, event flows, integrations, or consecutive delivery phases.

Budgetfrom $10,000
Format · 04

Support and development

For tools already in use: monitoring, incident review, small improvements, advice, and development without losing context. New sources, major features, integrations, and logic changes are estimated separately.

Budgetfrom $700 / month

Anonymized classes of work.

No company names, confidential details, or internal data. These are types of problems that reflect prior experience and can be rebuilt from scratch around your data and rules.

Example · 01 anonymized

Control of advertising and product data

Before

Data arrives from multiple platforms, event flows, spreadsheets, and internal reports. The team manually searches for discrepancies and weak points.

What is built

A consolidated report, validation rules, alerts, and a queue of cases that require attention.

Outcome

The team sees discrepancies, anomalies, and investigation tasks sooner.

Example · 02 anonymized

LLM-assisted recurring research

Before

The team manually searches for partners, competitors, segments, product hypotheses, or market signals.

What is built

Source collection, rule-based filtering, LLM analysis, a shortlist, and a recurring report.

Outcome

Less manual research, a regularly updated base, and explicit selection criteria.

Example · 03 anonymized

Events, postbacks, and MMP integrations

Before

Events, traffic sources, and reports do not form one reliable picture. It is unclear where data is lost and what should be checked first.

What is built

An event map, postback checks, exports, discrepancy analysis, a QA report, and priorities for the first fixes.

Outcome

The team understands which data can be used, where the risks are, and what to fix first.

Scope boundaries.

This track is about data and operational tools around acquisition, not about running paid media. The boundary is explicit so expectations remain aligned.

01

I work with data, events, reporting, integrations, and tools around acquisition. Campaign setup and media buying remain with your team or agency.

02

I do not promise sales growth, ROAS improvement, or lower CAC. I am accountable for the agreed technical result.

03

I work only with lawful clients, products, and transparent methods. I do not support gambling, gray financial schemes, platform-rule circumvention, traffic cloaking, or user deception.

04

The first sprint can include data-quality rules, alerts, QA reports, and queues of cases for human validation.

05

I do not reuse code, datasets, configurations, or internal materials from previous employers or clients.

06

The work is based on public sources, your own data, and systems for which you have legitimate access rights.

How the work proceeds.

We do not begin with a large build. First we understand the data problem, define the first useful result, and only then implement the tool.

Step 01

You describe the task

Which data sources exist, where discrepancies appear, what is done manually, and which result the team needs.

Step 02

Introductory call

We determine whether the task fits this track and whether the next step should be an assessment or a sprint.

Step 03

Data assessment

I review events, sources, attribution, reporting, access, limitations, and the expected operational outcome.

Step 04

We fix the first-release scope

We agree what is included, what is not, the timeline, budget, and acceptance criterion.

Step 05

Implementation and working reviews

I build the tool, show working parts, clarify details as needed, and keep the project within the agreed scope.

Step 06

Handoff, alerts, and next phase

Demonstration, alert setup, instructions, stabilization, and a plan for the next phase.

About

A technical partner for growth and data work.

I work across engineering, product, data, and delivery. I turn poorly defined data problems into a focused working result: backend, APIs, LLM workflows, event/data pipelines, reporting, alerts, or an internal interface.

I personally lead the first conversation, data assessment, first-release scope, technical design, implementation, and quality control. Communication is direct, and I take on a limited number of projects at a time.

  • 13+ years across software development, product, and project delivery
  • Hands-on CTO / Tech Lead combining implementation, technical decisions, and delivery management
  • Python, FastAPI, APIs, LLMs, backend, event/data pipelines, and integrations
  • MVPs, internal tools, and data automation
  • Experience with events, attribution, reporting, and data quality
  • Direct communication and a limited number of simultaneous projects

Frequently asked questions.

Short answers about advertising, assessments, agencies, MMP integrations, and data boundaries.

No. I am not a media buyer. I work with data, events, reporting, integrations, research, and internal tools around advertising and product workflows.

Yes. It is often the right entry point when the team first needs to identify where the data problem actually is and which first operational tool is worth building.

The introductory call qualifies the task and selects the next step. It does not include solution design or a detailed specification.

The paid Growth/Data assessment reviews sources, discrepancies, manual work, risks, the first operational outcome, and the next step. If a Working Tool Sprint starts within 14 days, the assessment fee can be credited toward it.

Yes, when the clients, products, and acquisition methods are lawful and transparent, and the work does not involve bypassing platform rules or misleading users.

I can work on reporting, events, integrations, data-quality checks, and internal tools, including in a white-label format.

Yes, when access and the task are clear. I can review events, postbacks, exports, and discrepancies, and build a focused reporting or QA layer.

Yes. A first sprint can include validation rules, alerts, reports, and queues of cases that need the team's attention. It does not replace growth or product expertise, but it helps surface discrepancies and suspicious changes sooner.

I do not transfer code, configurations, datasets, or internal materials from previous employers or clients. New tools are built from scratch using your data and lawful public sources.

Are events, reporting, attribution, or research still fragmented?
