lumel.dev
We take care of the technology so you can focus on your business
Two lines of work and one rule: technology adapts to your business, not the other way around.
We don't start from scratch. We don't force you into a template either.
Every business needs the same foundations. We already have them built and tested, so your budget and your time go into what makes your business different.
Built for you
- Your screens and your workflows
- Your business rules
- Integrations with what you already use
- Your brand, end to end
Already built
- Users and permissions
- Admin panel
- Online payments
- Electronic invoicing
- Catalog, stock and search
- Technical SEO and fast hosting
Compared with the alternatives
- WordPress, templates or Odoo
- Quick to start, but your business has to adapt to the system: plugins, modules you never use and per-user licenses that grow with you.
- Building from scratch
- It fits you, but it takes months and you pay again for what every system already has.
- lumel.dev
- A proven base plus full customization. Delivered in weeks, and changing something later does not cost a fortune.
AI where it helps, not because it is trendy
We use AI in our own work to build faster and spend more time understanding your operation. If an AI automation saves you hours, we will suggest it. If not, we won't sell you a chatbot you don't need.
Success stories
Projects in production, with clients who use them every day.
Training and maintenance, always included
We don't hand over a system and disappear. Every project starts by understanding your business and ends with your team using it.
- 1
Diagnosis
A conversation to understand how you work today and where time gets lost. Free of charge.
- 2
Proposal
What is worth doing, with which tools, how long it takes and what it costs. In writing.
- 3
Implementation
We build or configure in short iterations, so you see progress from the first week.
- 4
Training and support
Your team learns to use it and we stay close: support, adjustments and improvements.
Technology partners, not a code factory
At lumel.dev, we understand that a beautiful website is useless if it doesn't sell, and powerful software is pointless if no one knows how to use it.
That's why we don't start with technology: we start with how your business works. We choose what suits you —an existing tool, an automation or our own software— and leave it running, with your team trained.
We work in a simple, clear and close way, making sure every solution is genuinely useful day to day and adapts to our clients' way of working, not the other way around.
What we do every day
Joaquín Lumelsky
Founder of lumel.dev
I hold a degree in Social Communication from the University of Buenos Aires. I have always been passionate about technology, but before devoting myself to it I spent more than ten years in administration, deep in the day-to-day operations of a small business.
Since 2020 I have worked in technology: software development, tech education —teaching, creating content and leading academic teams—, IT project management and process automation with AI.
In 2025 I founded lumel.dev to help entrepreneurs and small businesses improve the way they work, implementing technology that solves problems instead of creating them.
