IMPACT90%+ pipeline acceleration · €50K+/year savings

PROBLEM

Slow, fragmented data pipelines were blocking every AI team. The existing vendor was expensive, hard to scale, and the team had grown too dependent on it.

APPROACH

Evaluated three vendors, wrote the summary that got C-suite sign-off on the €500K investment. Then coordinated 15+ engineers across teams and tracked all delivery milestones myself.

OUTCOME

Pipelines got 90%+ faster. €50K saved annually. Every AI team could finally move without waiting on data.

DEPLOYED

IMPACTFirst-ever real-time KPIs · Manual Excel process eliminated

PROBLEM

Support quality was invisible. Frustration rates and FCR were tracked manually in Excel. Always late, always slightly wrong, and nobody could act on them in time.

APPROACH

Replaced the Excel process entirely. Built a real-time platform tracking frustration signals and FCR across all support channels. Spent a lot of time with support leads figuring out what "good" actually meant for them.

OUTCOME

First real-time view of support quality the team ever had. They went from reacting to problems to catching them early. The Excel spreadsheet is gone.

SPEC-003Internal Tool

Internal HR Chatbot

Company-wide · 300 employees

DEPLOYED

IMPACT80% adoption · 2,200+ queries handled

PROBLEM

HR was buried in repetitive policy questions. No self-service existed. Employees waited days for answers to things that should take seconds.

APPROACH

Built a RAG prototype on internal HR docs before committing to anything. Rolled it out in phases and collected feedback to build trust. Didn't go broad until people actually wanted to use it.

OUTCOME

250 out of 300 employees adopted it within weeks. HR stopped being the bottleneck for routine questions. They now spend that time on things that actually need them.
