I co-founded Doscientos with @Gerard Martínez after watching companies overpay agencies that handed projects to juniors after the pitch, or settle for templates that never quite fit.
The pitch is simple: senior engineers, fixed price, 6 weeks to a working product.
What we build
Custom internal systems (CRMs, ERPs, portals)
For companies managing clients, orders, or teams in Excel or a generic CRM that doesn’t match their process. The exact tool they need - no monthly licences, no adapting the business to a template.
MVPs in 6 weeks
Booking platforms, marketplaces, B2B tools, internal management apps. We ship just enough to validate with real users - first customers are testing the product while competitors are still in Figma.
Process automation
We connect stores, ERPs, CRMs, and accounting systems. Orders flow into the ERP automatically, invoices generate themselves, reports run without human intervention. Measurable ROI in 2-3 months.
Legacy system modernisation
We migrate from Access, monolithic PHP, or Excel to modern architectures. While we build the new system, the old one keeps running. End users notice nothing - the business notices everything.
How we work
Most agencies share one thing: the senior who sold the project disappears once it starts.
At Doscientos, the engineers on the call are the ones who build the product.
6-week process:
| Week | What happens |
|---|---|
| 1 - Discovery | 60-min call to lock scope, not accumulate questions |
| 2 - Proposal | Deliverables, timeline and fixed price before writing a line |
| 3-4 - Development | Working demo every Friday, fast iteration, no bureaucracy |
| 5 - Testing | Tests with real users, bugs fixed in 24-48h |
| 6 - Launch | Production deploy, analytics, and 30 days of support included |
Commercial terms:
| Doscientos | |
|---|---|
| Price | Fixed, agreed before we start |
| Payments | 30% upfront / 40% midway / 30% on delivery |
| Code ownership | 100% client’s |
| Communication | Weekly demo + Slack throughout |
| Post-launch support | 30 days included |
| Urgent changes | Response within 24-48h |

My role
I lead the technical side: architecture, stack decisions, frontend development, code review, performance, and communicating scope and feasibility with clients.
Building Doscientos has sharpened my sense of product quality under delivery pressure - they’re not opposites.
