I get into the product, not just the code.

The people I work with — founders, business owners, early-stage teams — usually know exactly what they want to build. What they need is someone who can take that vision and execute it well: choosing the right tech, making good decisions under pressure, and staying involved from early planning all the way to a live product. I don't just deliver code. I help shape the product, challenge assumptions when it matters, and care about where things are actually heading.

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

What Problems We Solve

You have an idea, a process, or a gap in your business that software could fix. I turn it into something real — a web app, a dashboard, an internal tool — built around how your team actually works, not a generic template.

  • Custom web apps built around your specific workflow
  • From rough idea to live product — without the tech overwhelm

If your team is copying data between systems, running the same report by hand every week, or doing tasks that always follow the same steps — that's exactly where AI can save real hours. I find what's worth automating and build it properly.

  • Cut the manual work eating your team's time every week
  • You see exactly how it works before it touches anything critical

Your business has years of knowledge locked in documents, emails, and internal systems. I connect that to a language model so your team — or your customers — can ask questions and get real answers from your own data, not generic AI.

  • Let your team query your own docs, policies, and data in plain English
  • Customer-facing chat that actually knows your product and your business

Not every process needs AI — and trying to automate everything at once usually makes things worse. I help you find the one workflow that's genuinely worth automating first: small, specific, measurable. Then we build it properly and grow from there.

  • Start with one high-frequency task, not a full operational overhaul
  • Agents your team barely notices — because they fit how you already work

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.
