I help founders turn rough ideas into real, working products.

I've spent 4+ years working with early-stage startups and small businesses — building features, setting technical foundations, and shipping products that solve real problems. Lately I've been focused on helping businesses implement AI and automation to remove friction and grow faster.

Most businesses don't need more tools. They need the right ones, built well, fast, and tailored to their specific problems.

Case Study

Real problem, real results

A cleaning company managing 800+ workers — everything done manually, on spreadsheets.

Cleaning Operations Platform

Reports, absences, shift hours, and worker contracts — all coming in through WhatsApp messages, all processed manually. With a team of 800+, the overhead was becoming the job.

Problem

Every report, absence and shift — entered by hand, every day.

Process

Understand their real workflow and find where time was being lost.

Solution

Employees keep using WhatsApp. An AI understands each message and updates the records automatically.

Results

40% less time on admin. The team now focuses on people, not paperwork.

Testimonials

Client Testimonial

A few words from people I've actually worked with.

”

We were doing everything in person — no website, no system, nothing online. We didn't really know what we needed or where to start. Edi listened, gave us options that made sense for us, and was patient throughout the whole process. Now we manage our clients and appointments in one place and people can actually find us online. It's made a real difference to how we run things day to day.
