//CUSTOM DEVELOPMENT & AI SOLUTIONS

Tools built for you.

Have your processes outgrown your software? Freelance developer, I build what they're missing: custom apps, automations, AI agents and dashboards for SMBs — designed around your reality, not the other way around.

Let's talk about your project//

Behind , one person: me.

20 years building tools in enterprise IT,

10 years in Shanghai, where technology waits for no one,

2 years embedding AI into business tools,

and one simple conviction

— the best enterprise tools aren't bought,

they're built.

//PATTERN

The vicious cycle.

The cycle is almost always the same. I see it in 8 SMBs out of 10.

Constat01

Your tools no longer keep up.

Your software covers 80% of the need. The remaining 20% gets done by hand, in shared spreadsheets, or in someone's head.

Constat02

The team fills the gaps manually.

Your best people spend 30 to 50% of their week on repetitive work, no longer doing their actual job. Email follow-ups, quotes, reminders, manual data entry… High-value work disappears.

Constat03

Your 6 tools don't talk to each other.

Export, reformat, copy-paste, re-enter, re-import… The data becomes fuzzy. Important decisions get made on gut feel.

Constat04

One person is out, the company stutters.

One person knows the whole process — the history, the exceptions, the workarounds. They go on vacation and everything slows to a crawl.

Constat05

No one has time to structure things.

So it keeps going. So volume smothers the organization even more. So the existing tools keep up even less.

Constat06

Your costs creep up silently.

Every six months: a new software subscription and an intern to plug the gaps. You pay twice — for the generic solution, and for the human labor to make it usable.

//SERVICES

What I build.

Four areas, one approach:
start from your real problem,
build the solution.

Custom applications

Internal tools, websites, client portals, team workspaces. When generic solutions can no longer keep up with your business logic, I build the tool that does — sized to your processes, not the other way around.

Workflow automation

The repetitive tasks that eat up your weeks all have a hidden cost. I identify the bottlenecks, build the automations that make them disappear, and your team reclaims its hours.

AI agents

Smart assistants that handle customer service, analyze your data, prepare your decisions. Designed for a specific use, not to impress — evaluated on what they replace, not on what they promise.

Custom dashboards & AI reporting

Your data is already there, scattered across your tools. I centralize it in clear dashboards, with the right indicators, updated in real time. You stop compiling, you steer.

//METHOD

How it goes.

Simple, clear, no bad surprises.

01

Understand

We talk for 30 minutes. You explain your context and your problem, I honestly tell you if it's in my wheelhouse and whether it's worth it. If not, I point you elsewhere.

02

Scope

If we move forward together, within 48h I send you a fixed-price quote with a precise scope, a deadline, and a proposed phasing. No fuzzy hourly rate, no surprise overruns.

03

Build

I develop, I show you intermediate versions regularly, you adjust as we go. You stay in control from start to finish.

04

Hand over

I deliver the tool with the code, clear documentation, and a handover session. What I build belongs to you, with no proprietary lock-in.

//VALUES

Three non-negotiable rules.

Applied on every project.

No jargon.

I talk about what will change in your day-to-day, not about the tech stack. You understand what you're buying.

Fixed price or nothing.

Every engagement has a scope and an amount set in advance. If the scope evolves, we talk before, not after.

You keep everything.

Code, data, documentation, access. At the end of a project, you can continue with me, with another provider, or on your own. Never locked in.

//ABOUT

My name is Édouard, I'm a developer and I live in France after ten years in China.

I've spent a large part of my career building business tools for companies that couldn't find what they needed in off-the-shelf products — internal ERPs, management applications, client portals, websites, bridges between different applications, custom integrations and automations, innovative solutions powered by AI, data visualization tools, and so on.

Today, I operate under the name Epsiio as a sole proprietor, and I deliberately choose to stay independent to keep a direct relationship with every client.

If you work with me, I'm the one who replies to your messages, I'm the one who writes your code, I'm the one who delivers. No middleman.

A project in mind ?

The first conversation is free and with no strings attached. We'll look together at whether what you're after is in my wheelhouse, and we'll only move forward if it makes sense for you and me.
