Andrés Atencio

Software Developer · IT Teacher

I’m a software developer and IT teacher based in Buenos Aires. For around fifteen years I worked professionally in software, mostly on existing web and mobile products. In late 2023, teaching Information Technology became my main professional work.

I kept developing software through educational, institutional and personal projects. Now I’m building an independent software practice alongside teaching, and development is once again a central part of my work. I’m looking for remote contract or freelance work where collaboration can be mostly asynchronous.

Experience

From 2008 to 2023, I worked continuously as a software developer across web, desktop and mobile systems. Much of my experience was in back-end development, databases, APIs and integrations, and over time my work became increasingly full-stack.

I mostly worked on existing products and systems, from logistics and mobile-content platforms to surveys, healthcare and online communities. The work included understanding existing behavior, defining technical approaches, implementing and testing changes, working with data and migrations, and following changes into production when needed.

Software development

I worked on web and mobile products across surveys, healthcare and online communities, in distributed teams working in English. I joined Manas with a stronger back-end background and gradually worked across more of the stack, including substantial front-end work in later years. On Surveda, where I worked for several years, work often began with a product need rather than a prescribed implementation: clarifying scope, investigating the codebase, defining a technical approach, implementing and testing changes, and following selected changes into production. The work included APIs, integrations, database changes and migrations. On Surveda I worked with Elixir/Phoenix and React; across Manas projects, the work also involved JavaScript/TypeScript, Python, Node.js, Ruby on Rails, PostgreSQL and Flutter/Dart.

I worked on web and mobile systems for subscription, distribution and download of digital content, including APIs, integrations and SQL-backed application work. Technologies included Android/Java, C#, ASP.NET, Angular and SQL Server.

I developed web and desktop applications, including logistics and distribution systems. Technologies included C#, ASP.NET, Visual Basic and SQL Server.

Current development

Alongside teaching, my development work today spans institutional tools, software for teaching and learning, and personal projects.

Institutional tools

Tools for institutional needs, including a bulletin-generation tool I developed and continue to maintain for CFP No. 7.

Teaching and learning

Web projects for teaching and learning, including Aula, a website where I publish materials I use in class so they can be projected, consulted and revisited later.

Personal projects

Projects for my own work, including a versioned, recoverable development environment across Windows and WSL, with verification and shared working conventions.

Teaching and technology education

I teach Information Technology in Buenos Aires City high schools and serve as Head of IT Training for CFP No. 7’s high school IT track.

At CFP No. 7, I coordinate the IT track’s vocational training and its integration with the general high school curriculum, and teach courses in systems architecture, web interfaces and final projects.

I design my own materials and teach through hands-on projects. Over the track’s four years, students move from block-based programming in educational environments to writing code, building and publishing web interfaces, and working on projects in their final year.

From 2019 to 2020, while working professionally in software, I also taught introductory programming, persistence and user interfaces in UNAHUR’s University Programming Technician program.

Background

Academic foundation

I studied at Colegio Nacional de Buenos Aires, a pre-university high school of the University of Buenos Aires. Its broad, demanding curriculum remains an important part of my intellectual foundation.

Systems

I graduated from Universidad del Salvador as an Information Systems Analyst.

Across disciplines

My academic path also included several years of university study at the University of Buenos Aires, mainly Veterinary Medicine and later Literature, and teacher training in Biology. I’m currently completing pedagogical training at IES Juan B. Justo, with 12 of 15 course units completed.

Working together

I’m comfortable taking ownership of a well-defined project or piece of work, from investigation and technical approach through implementation, testing and delivery. Much of my experience is in existing products and codebases: fixing bugs, adding features, building integrations and making data changes. I also design and build new tools and systems from scratch.

I’m available for remote contract or freelance work, from short, focused projects to sustained engagements, with the time commitment agreed case by case. I work best when development time can be arranged flexibly across the week and collaboration is mostly asynchronous; scheduled meetings and some overlap with the team are fine.

A good place to start is a free 15–20-minute call to see whether there’s a fit. For focused questions we can work through in conversation, I also offer paid consultation sessions by appointment. When something needs more, such as research, codebase review, problem reproduction, implementation or written deliverables, we can scope that work separately.
