Next project / Planned

Mapslyfy

Android / Google Maps / Business Profile

Hundreds of phones. One coordination layer.

My next project will focus on managing hundreds of Android phones running Google Maps and coordinating interactions with Google Business Profile listings, formerly Google My Business.

The aim: bring devices, task planning and execution tracking into one place. A product direction I am preparing, with no launch date announced yet.

02 / How I can help

Start with the bottleneck.

A process taking too much time. A product that needs to exist. A technical decision nobody owns. That is where I come in.

Explore services
01

Custom software & SaaS

Your tools no longer fit.

Build the product your business needs: an MVP, a SaaS platform or a system that standard tools cannot cover.

02

Automation & applied AI

Your team repeats the same work.

Turn repetitive tasks into reliable workflows. Use AI for classification, extraction or assistance where it earns its place.

03

Internal platforms & integrations

Your systems do not talk.

Connect APIs, data, CRM and backoffice tools so people can work from one coherent system.

04

Fractional CTO & infrastructure

You need someone to own the technology.

Technical direction with hands-on execution: architecture, product decisions, delivery and infrastructure.

03 / Working together

From “we need to” to “it works”.

  1. Understand

    We look at the business, the current process and what a useful result would look like.

  2. Decide

    I turn the problem into a plan: scope, trade-offs, priorities and a first deliverable.

  3. Build

    Working software, regular reviews and decisions you can follow. The product stays close to its users.

  4. Operate

    Deployment, documentation and visibility into the system. We agree what maintenance comes next.

04 / The person behind the code

A CTO who still builds.

I’m David Rodríguez, also known as esedark. I work across product, software and infrastructure, based in Dubai and collaborating internationally.

I like understanding how a business actually works: where time is lost, where information gets stuck and what the team cannot do with its current tools. Then I build the missing piece.
