Case Studies
No mockups. No slide decks. Every project addresses a concrete, operational problem — and was solved with real code.
E-Commerce & Product Configuration
690 orderable product variants — without a single sales call.
The Problem
The company sold highly specialized measurement products with dozens of variables: material, geometry, measurement range, width, mounting. The ordering process ran exclusively via phone and PDF catalog — error-prone, time-intensive, and not scalable.
The Solution
Development of a guided 5-step product configurator with live price calculation, 690 standard SKUs in a structured database, and direct cart integration. Custom orders are automatically forwarded as quote requests.
Results
Who this is for
Manufacturers and distributors with variant-rich products who still rely on phone or email inquiries.
Data Structuring & CRM
472 customers. 10,480 records. From the archive to CRM in one week.
The Problem
Two decades of orders — spread across hundreds of PDFs and Excel files. Who the best customers were, which products performed, where revenue came from: nobody knew for certain.
The Solution
Automated extraction and structuring of historical business data from 1,841 PDFs and 763 Excel files. Building a clean customer database with CRM functionality, revenue classification by product category and country, plus 80% automatic email attribution for reactivation campaigns.
Results
Who this is for
Companies with years of data in Excel, PDFs, or legacy systems — who finally want to know who their customers really are.
Website Relaunch & Technical Infrastructure
Complete website rebuild. 23 pages. 3.5 weeks.
The Problem
The existing WordPress site neither reflected the product portfolio nor the company's expertise. A relaunch was considered costly and risky internally — and was therefore postponed for years.
The Solution
Complete rebuild as a modern React web application: 23 pages, responsive design, automated deployment via CI/CD pipeline, SSL encryption, GDPR-compliant cookie banner, animation system, and performance optimization. Development, testing, and deployment in 3.5 weeks.
Results
Who this is for
Companies with an outdated online presence who want a relaunch — without months of agency processes and unpredictable budgets.
Web Security & Compliance
3 independent security audits. 25 measures. 0 open vulnerabilities at launch.
The Problem
A new webshop goes live — but who actually checks if it's secure? Most SME websites are deployed without structured security review. The risk is only noticed when it's too late.
The Solution
Three consecutive security audits during development: API key rotation, credential removal from Git history (53 commits), tightening database access rights, CORS policy restriction, implementing complete HTTP security headers (CSP, HSTS, X-Frame-Options), and fixing a prototype pollution vulnerability in a dependency.
Results
Who this is for
Companies running a webshop or data-processing platform — who want to ensure security is built in from the start.
Strategy Consulting & Digitization
Build too much too early and you fail. Prioritize right and you're live in weeks.
The Problem
The company wanted a webshop. But product data was unstructured, the SEO foundation was missing, and without a clear scope, the project threatened to take months and never finish.
The Solution
Strategic preparation phase before the first code: analysis and structuring of existing product data, definition of a lean MVP scope, derivation of an SEO keyword set from technical documentation, building an ERP-compatible data model, and setting clear boundaries between phase 1 and later expansion stages.
Results
Who this is for
SMEs who want to digitize but don't know where to start — and who want to make sure the money in phase 1 isn't spent on things that are only relevant in phase 3.
Business Intelligence & CRM
Instead of data chaos in Outlook: A CRM that makes pipelines and potential visible in seconds.
The Problem
Customer communication, active quotes, and historical invoices were scattered across different systems (Outlook, ERP, Excel). There was no central overview where sales closures, upcoming tasks, and the status of inactive customers were visible at a glance.
The Solution
Development of a robust CRM dashboard providing a complete Customer-360 view. Through a multi-stage data pipeline and intelligent domain matching, over a thousand unstructured emails were bundled and automatically assigned to the correct contact.
Results
Who this is for
B2B companies whose sales processes suffer from system breaks between email, quoting software, and spreadsheets.
Data Enrichment & BI
Who drives the most revenue? Data that suddenly delivers hard facts.
The Problem
Even though 15 years of sales history existed, it was semantically useless: quote items were pure free text. Nobody could ad-hoc name the top 20 recurring customers or which industry segment generated the most revenue.
The Solution
Programming a custom product-type classifier (heuristics & keyword matching) that analyzed 3,491 unstructured quote lines. Simultaneously, hundreds of companies were automatically mapped to industry segments (utilities, municipalities, construction).
Results
Who this is for
CEOs and sales teams who want to replace gut feeling with hard facts mined directly from their own data.
Business Intelligence
From unreadable Excel archives to an interactive live customer map.
The Problem
Dozens of customer references and installation sites existed purely as text fragments across disparate sheets. Stakeholders were unable to grasp the true geographical footprint of the company's products visually.
The Solution
Mining thousands of historical orders for location data, cross-referencing with public registries (e.g. eHYD), and building an automated geocoding pipeline. The result is a high-performance interactive web map fed directly by the CRM database.
Results
Who this is for
Companies with numerous installation sites or references that want to visually prove their market penetration online.
