Consulting

Interested in working together or just having an informal chat? Hit me up at adolfo@ochagavia.nl any time.

Key areas of expertise

I’m currently offering the following services:

• Systems programming. I thrive when a programming challenge involves a technical deep dive. For instance, I recently designed and implemented a container image builder, registry and runtime in collaboration with Outerbounds (see this article for details and benchmarks). Other past consulting engagements include implementing the MySQL wire protocol as a library, developing a CDCL dependency solver, and creating a continuous benchmarking system for the popular rustls library.
• Boosting Rust open source projects. I’ve been contributing to the Rust ecosystem since 2014. I’m used to designing, implementing and polishing features in collaboration with project maintainers. For an example, check out this article about a project for ISRG (makers of Let’s Encrypt). Other past customers were Prefix.dev, Stormshield and the Solana Foundation.
• Free-form consulting. If there’s anything else you feel I could help with, let’s talk and find out whether my skills could bring you closer to a solution.

Testimonials

The excerpts below are a selection from received LinkedIn recommendations.

Josh Aas, co-founder of Let’s Encrypt and director of ISRG:

[Adolfo] put together a clear plan, iterated on it (…), and then did an excellent job implementing it (…). I would absolutely have Adolfo work on projects for us again in the future.

Dirkjan Ochtman (@djc), open source maintainer of well-known Rust crates:

Adolfo was able to quickly get up to speed with our open source project (…). He was eager to tackle our feedback to pull requests, and a very pleasant person to interact with. Highly recommend working with him!

Wolf Vollprecht (@wolfv), founder and CEO of Prefix.dev:

We can absolutely recommend working with Adolfo on challenging computer science problems.

Jeroen Heijmans (@jeroenheijmans), CTO at Infi Utrecht:

His technical skills make him part of the top 1%, even regardless of the specific technology!

Matthew Quinn, software engineer:

I have to credit a great deal of my skills already to the advice and guidance that he has provided me with over this past year.

Technologies of choice

My strongest stacks are Rust and .NET (C#). I also have work experience in TypeScript, Go, Java, Python, Elixir and C. Given enough time, I’m able to get familiar with whatever technology you are using.

Ways of working together

• Solo. I am a very intrinsically motivated person, and have a proven track record delivering high-quality work with little guidance. I proactively ask the right questions to clarify assumptions and goals, and I research my way forward through any obstacles that might appear. I am also able to summarize and explain a project’s progress in such a way that you can follow along without being burdened with day-to-day minutiae.
• Team. Peers see me as a highly talented and pleasant team member (see testimonials above). My technical skills are accompanied by the capacity to effectively collaborate with others: I feel comfortable mentoring junior programmers, solving architectural challenges with experienced developers, interfacing with business stakeholders, and more. If you are looking to boost your team, I’d be happy to be on board.

Practicalities

• Location. I am based in Amsterdam and have a preference for remote work.
• Working across time zones. I have experience collaborating with colleagues in different time zones (mainly US and Europe).
• Working hours. I am interested in projects for 3 to 4 days a week, 8 hours a day.
• Languages. I am fully proficient in English, Dutch and Spanish.
• Company. I am registered as a one-person company (eenmanszaak) at the Dutch Chamber of Commerce, under number 80893503.
• Legal. I work under these terms and conditions (also available in Dutch).
