Platonic.Systems

Custom Software Development Consulting for Mission-Critical Systems

Custom Software Development
Consulting Built for
Complex Requirements

Got an idea for a novel software solution but aren’t sure how to build it? You supply the vision, and we’ll provide all of the expertise and support needed to bring it to life.

  • End-to-End Software Engineering

    From initial discovery and system design to development, testing, and deployment, we handle the full software lifecycle. Our engineers focus on building systems that remain maintainable and extensible as your product evolves.

  • Functional Programming–Driven Architecture

    We apply functional programming principles to eliminate entire classes of bugs, improve security, and ensure predictable system behavior. This approach enables us to deliver software that is easier to reason about, test, and scale.

  • Machine Learning & Data-Driven Systems

    Looking for software that adapts, predicts outcomes, or uncovers insights from your data? We design and integrate machine learning systems that evolve alongside your business needs.

Testimonial

Platonic.Systems is our go-to developer partner when we need to solve complex and complicated use cases. They truly add a tremendous amount of value during use case development and proof of concept iterations that have helped us advance with our computer vision and machine learning opportunities.
  • Why Choose Platonic.Systems

    We design systems that deliver value years after launch. Objective architecture decisions, transparent development, full IP ownership, and software designed for growth and compliance.

  • Technologies We Use

    We choose technologies for reliability and sustainability — not trends. Haskell for backends, Nix/NixOS for infrastructure, PureScript and Elm for frontends, Python and Julia for ML.

  • Tailored Solutions

    Whether you need full-cycle development, architectural guidance, or specialized engineering expertise, we deliver custom consulting tailored to your exact requirements.

Frequently Asked Questions

What kind of software projects does Platonic.Systems take on?

Complex systems where correctness matters. R&D projects, financial software, blockchain systems, machine learning pipelines, compiler and language tooling, and anything involving formal verification. We like problems that are technically demanding — "we've tried everything" is a good starting point for a conversation.

How does the engagement process work?

Initial consultation (free, 30 minutes) to understand your needs. If there's a fit, we propose a discovery or proof-of-concept phase to validate the approach. From there: iterative development with regular check-ins, then handoff with documentation and optional ongoing support.

What happens after the project is delivered?

You get complete source code, documentation, and knowledge transfer. We train your team on the codebase. Optional maintenance retainers are available if you want ongoing support, but our goal is to deliver software you can own and extend independently.

How do you handle changing requirements?

We work iteratively, so requirements can evolve without derailing the project. That said, we'll push back if a change undermines technical soundness. Honest guidance is part of the service & mdash; we'd rather have a difficult conversation than deliver fragile software.

What technologies do you specialize in?

Haskell for backend systems, PureScript and Elm for frontends, Nix for infrastructure, Python and Julia for ML/data work. We use functional programming across the stack. See our Haskell consulting and NixOS consulting pages for specifics.

What makes Platonic.Systems different from other consultancies?

Functional programming expertise and a correctness-first approach. We're a small, senior team — no junior developers learning on your project. Our clients include Anduril, Mercury, Tweag, and Condé Nast. We specialize in problems that other shops can't or won't take on.

What services are included in software engineering consulting?

Architecture design, full-stack development, DevOps and infrastructure, machine learning systems, formal verification, and technical training. Scope depends on what you need — sometimes that's a complete system build, sometimes it's architectural guidance for your existing team.

How can functional programming improve software engineering outcomes?

Fewer bugs (type systems catch errors at compile time), easier testing (pure functions are trivially testable), better maintainability (explicit data flow, no hidden state mutations), and more confident refactoring. The tradeoffs are a steeper learning curve and smaller talent pool — but the long-term ROI is significant.

How do I start a software engineering consulting project?

Schedule a free consultation . We'll discuss your project, technical constraints, and goals. No commitment required — sometimes the best outcome is pointing you in a different direction.

Who benefits most from software engineering consulting?

Startups that need senior expertise without full-time headcount. Enterprises modernizing legacy systems or adopting new technologies. Anyone with a hard problem and a deadline. If your existing approach isn't working, let's talk.
