About Jesus

An experienced Backend / Full-stack software engineer. For +15 years I have worked with international companies (Bonhams, Kayak, Lastminute, Massimodutti), universities and institutions, helping them developing software and marketing tech projects. (see mejuto.co)

My services:

// Backend / Full-stack software development
Developing your website, app, or prototype. I can execute the whole full-stack: (Frontend, Backend, Databases, Deployment) to make your company's vision a reality.
I like to work with React and Django, but I am experienced with many other technologies. I am happy to talk.

// Staff augmentation
Do you need a hand to finish your project? I can join your team of developers to help.

// Legacy code
Do you have a piece of code that nobody dares to touch? I can write tests and help you add features to it. I am not afraid of tricky legacy code.

// Automation
Some manual processes waste an unreasonable amount of time — and time is money. I can help you automate tasks and processes your business relies on.

// Team training
Do you want to get your team up to speed with a new technology? I can teach custom Full-stack programming courses on-site at your company.

// Assessment
Do you need advise on a strategic technical decision? Wondering for which roles to hire or how to start planning a new project? I can help you and your team evaluate the situation and prepare a plan.
