An engineering partner
for always-on platforms.

Wellnuts is a deliberate engineering studio. We work with a small number of long-term clients on the kind of systems that don't get to fail — high-load IoT backbones, real-time streaming infrastructure, EV charge-point networks.

How we work

Senior-led. Long-horizon. Deliberate.

Every engagement is led by senior engineers. We take on the work we can do exceptionally, and only that — not the work that fills the calendar.

Our partnerships run for years. Not because we lock anyone in, but because the systems we build need years of compounding attention to keep paying off. We come in early, sit in standups, share roadmap decisions, and stay accountable to the same engineering metrics our clients answer to.

The deep stack — Elixir, Erlang/OTP, Go, Rust — is the surface answer. The real answer is that we treat reliability as an architecture problem, not an ops problem. When a platform must stay up, we know where the load goes first, where the cost compounds, and what to over-design on purpose.

Why clients come to us

Does Wellnuts make
your engineering shortlist?

The engagements we take on tend to fall into one of four categories. If these line up with the criteria you're evaluating against, the conversation is usually a short and productive one.

01

Depth across the industries we serve

Over a decade of shipping production software — EV charging networks, connected fleets, smart-home platforms, streaming and media, fashion-tech. Patterns earned from real systems running for years, not pitched from slide decks.

02

High-load engineering that holds at real-time

When a platform must absorb hundreds of thousands of devices, millions of concurrent connections, or sub-second video at scale, the architecture problem tends to end up on our desk. 200k+ IoT devices in a single tenancy; viral-scale real-time chat; sub-500ms WebRTC delivery — the same engineering primitives, applied where they earn their keep.

03

Security as an architecture decision

The clients we work with treat security as a data-layer concern, not a compliance retrofit. SOC 2, ISO 27001 and GDPR controls — engineered into the data plane from day one, continuously updated against modern safety standards.

04

Tech stack chosen on purpose

Elixir/OTP for the parts that must not go down. Go and Rust where raw throughput pays. The deep stack isn't a trend — it's the correct answer for platforms that have to survive their own growth curve. We architect for the next 10× of load, not the current one.

    The deadline set by the vendor was short, parallel to the level of work difficulty and work quantity completed. Wellnuts delivered the work ahead of the deadline. After the completion of the system, the vendor team consistently fulfilled revisions when required.

    Wellnuts built our entire EV charging management portal from the ground up, including key functional modules, server architecture, and UI. We've been working together for over 4 years, and the team provides ongoing support and expands our system. We highly recommend Wellnuts as a reliable IT partner.
