11+ years building automation and custom applications for large enterprises — across environmental services, industrial operations, retail, and business-critical internal tooling.

My core work: Apps Script add-ons, AppSheet solutions, VBA-to-Workspace migrations, and Python cloud automation on GCP. I've shipped through partner consultancies into Fortune-scale environments where downtime isn't an option.

Bachelor's in Business IT, finishing a Master's in Media Informatics at TH Köln. Native French, fluent German (C1), English and Arabic — four working languages, no translation layer.

What I build, end-to-end.

01

Apps Script Automation

Purpose-built workflows in Sheets, Docs, Forms and Gmail. Designed to survive auditor scrutiny and outlast team turnover.

02

AppSheet Development

No-code and low-code internal tools that actually reach production: mobile-ready, role-aware, governance-friendly.

03

Google Workspace Add-ons

Custom sidebars and menu extensions for Sheets, Docs and Forms. Deployed privately for your team or published to the Marketplace.

04

API & Integration

Connect Workspace to your CRM, ERP, cloud storage and analytics. No fragile Zapier chains.

05

Excel / VBA Remediation

Legacy macros and shared-drive spreadsheets rebuilt as maintainable, version-controlled cloud systems.

06

Python on GCP

For the heavy lifting Workspace wasn't built for: App Engine, Cloud Run, Firestore, Cloud Storage.

Four phases. No drama.

PHASE 01→

Discovery

Map the real workflow — not the wishlist. Stakeholders, edge cases, the spreadsheet nobody admits exists.

  • Stakeholder interviews
  • Process audit
  • Risk & ROI assessment
PHASE 02→

Design

Architecture, data model and UX specs your team can actually approve — written in the language they speak.

  • Solution architecture
  • Data & security model
  • Approval-ready specs
PHASE 03→

Build

Apps Script, AppSheet, GCP — shipped in iterative weeks, not multi-quarter waterfalls. Code reviews included.

  • Iterative releases
  • Versioned codebase
  • QA & UAT support
PHASE 04●

Adopt

Training, documentation, and clean handover. Tools that get used six months later — not shelved.

  • Team training sessions
  • Living documentation
  • Post-launch support

Anonymized. Real.

Questions, before the call.

Both. About half my engagements come through partner consultancies who need a senior Workspace specialist on the bench; the other half are direct enterprise contracts. I'm comfortable invoicing either side.
Anywhere from a 2-week discovery sprint to multi-quarter builds. Most projects land in the 3–9 month range — Discovery → Design → Build → Adoption — with iterative releases instead of one big-bang launch.
Yes. I'm based in Braunschweig, travel comfortably across DACH and France, and I run hybrid engagements regularly. On-site days for kickoff and stakeholder workshops are usually a good idea.
Discovery sprints typically within 2–3 weeks. Full builds depend on current contracts — book a call and I'll be straight about timing.
Native French and Arabic, fluent German (C1), fluent English. Workshops, specs, training, documentation — all four. No translation layer needed for French, German or Arabic teams.
Always. I've worked under enterprise InfoSec frameworks across regulated industries; standard NDAs, DPAs and security questionnaires are routine.
