Manual data entry, scattered website data, and unstructured video slow teams down. I build document extraction, n8n automation, and computer vision workflows to make that information usable.
Selected work in data extraction, OCR, and computer vision. Each case study shows the problem, the build, and the outcome.
An n8n invoice workflow extracts headers and line items, translates descriptions, checks totals, and sends reviewable data to Google Sheets for an Excel handoff.

Hourly engagements, from €45/hour. Each offer shows its timeline, with in- and out-of-scope details on its own page. Estimates go through the contact form.
A focused buildout for teams stuck copying information from websites, PDFs, invoices, or messy internal sources.
I build and fine-tune computer-vision models for image and video tasks, with inference optimization where needed.
A complete workflow build for operations teams that need LLMs, n8n, APIs, scraping, and human review connected into one dependable system.
Real projects. Real impact.
“Vivek is by far the best developer I have worked with. He is extremely passionate and fully committed until a solution is found. He is also very fast and clear in his communication, which makes working with him both easy and efficient.”
I optimize complex AI systems for production, from real-time inference acceleration to automated data extraction at scale.
Here's exactly what to expect. I deliver a clear process, regular updates, and production-ready results.
We'll start by understanding your data challenges, constraints, and success metrics to define the right approach—whether it's vision system optimization, data extraction, or a custom AI workflow.
I build, test, and optimize the solution with production-grade performance standards. I deliver robust, working systems, not just prototypes.
Let's build your next AI solution together. You'll get production-ready code, clear communication at every milestone, and 30 days of support after delivery—so your team never feels stuck.
