Nordic Engineering Consultancy

Independent specialists in web performance, caching, and delivery.

Nordcache is an engineering consultancy working at the infrastructure layer: content delivery, reverse proxying, and application caching. We advise, design, and build for organisations that take web performance seriously.

Based in Umeå, Sweden
I.

The practice.

Nordcache is a specialist consultancy focused on the layer between an application and its users. Our work covers content delivery, reverse proxying, and application caching, and the architectural decisions that connect them.

We are vendor-neutral. We do not resell platforms, and we have no commercial preference for any particular stack. Recommendations are made on technical grounds, in the interest of the system and the team that operates it.

Our clients are typically engineering teams who already understand their systems well and want experienced, independent input on a specific problem: an audit, a redesign, a piece of bespoke software, or a longer collaboration. We work with a small number of clients at a time so that each engagement receives full attention.

Practice areas.

01 Content delivery CDN architecture, edge caching strategy, origin shielding, and cache invalidation design. We work with managed CDNs and with custom multi-PoP setups where they are warranted. Architecture
Strategy
Implementation
02 Reverse proxying Routing, TLS termination, header and request logic, load balancing, and rate limiting. Configuration of established proxies, and bespoke proxy software where the standard tools fall short. Configuration
Bespoke software
Operations
03 Application caching In-memory and distributed caches, query and computation caching, and invalidation strategies matched to the data and the consistency requirements of the system. Design
Integration
Tuning
04 Architecture review Independent technical review of an existing caching and delivery setup. Findings are documented for engineers and decision-makers, with prioritised, practical recommendations. Audit

How we engage.

Consulting

Advisory & review

Time-boxed engagements focused on a specific question: a performance assessment, an architecture review, or expert input on a planned change. Deliverables are written for the team that has to live with the result.

Design

Architecture & specification

For teams planning a significant change to their caching or delivery layer. We define the architecture, document the design, and agree on the specification with you before any implementation begins.

Build

Bespoke implementation

Where standard tooling is not the right fit, we develop bespoke software. Built to be readable, operable, and maintainable by your team after handover.

Retainer

Ongoing collaboration

Continued access to the practice for monitoring, tuning, and incremental improvement as the system evolves. Suited to clients with sustained performance requirements and limited in-house specialist capacity.

IV.

Security by design.

The caching and delivery layer sits directly in the path of every request. It terminates TLS, inspects headers, holds sensitive responses in memory, and decides what reaches the origin. Mistakes at this layer are quiet and consequential, so we treat security as part of the architecture, not as a review step at the end.

In practice, that means working with a clear threat model for each engagement, designing cache keys and invalidation logic so that responses cannot be served to the wrong user, terminating TLS with modern ciphers and sensible defaults, and keeping the surface of bespoke software small and auditable.

We pay particular attention to the failure modes that are specific to this layer: cache poisoning, response smuggling, header injection, and accidental leakage of authenticated content into shared caches. Where we build, we build conservatively. Where we advise, we say plainly what we would and would not put in front of users.

About & contact.

Nordcache is an independent consultancy based in northern Sweden, working with clients across the Nordics and Northern Europe.

We work remotely with engineering teams that value technical depth and clear, considered communication. New engagements are scoped from an initial conversation; there are no off-the-shelf proposals.
