Nordic Caching & Web Performance
We consult, design, and build bespoke caching and web performance solutions — from CDN infrastructure to reverse proxies and data caching layers. Every engagement starts with your problem, not a product catalogue.
Our principles
01
Our caching software is built for production environments where failure is not an option. Conservative dependencies, battle-tested code paths, and graceful degradation under load.
02
No black boxes, no sprawling configuration. Every component does exactly one thing well. You can read the code, understand it, and trust it — because we can too.
03
Every millisecond counts. Our software is profiled and benchmarked against real-world traffic — not synthetic tests designed to look good on paper.
How we engage
Every organisation's infrastructure is different. We don't sell licences or hand you a box to install — we work with you to understand what you actually need, then design and build something that fits your stack, your team, and your traffic.
That might mean a full caching layer, a targeted performance audit, or ongoing engineering support. We scope every engagement from scratch.
Discuss your requirements →A structured engagement to identify where time and resources are being lost. We analyse TTFB, cache hit ratios, origin load, and CDN behaviour, and deliver a clear, prioritised roadmap — not a generic report.
We write caching software tailored to your exact requirements — from a targeted caching layer to a complete custom-built caching server. No off-the-shelf middleware dressed up as a solution.
An independent expert review of your existing caching and proxying setup. We identify risks, bottlenecks, and opportunities — and explain them plainly, without jargon.
Ongoing access to our team for monitoring, tuning, and evolving your solution as traffic grows and requirements change. We become part of your extended team, on your terms.
Areas of expertise
We don't dabble. Our work covers three tightly related domains — and the intersections between them are where the most interesting problems live.
01 / CDN Solutions
Custom CDN software and infrastructure design for organisations that need more control than a managed CDN service provides — or that operate in regions where off-the-shelf CDNs fall short.
We design multi-PoP caching topologies tailored to your user geography and origin setup — cache hierarchies, shield layers, and routing logic that you own and understand.
Surgical, tag-based, and time-based purging strategies. We build invalidation pipelines that keep your CDN edge fresh without hammering origin or causing stale content issues.
Request coalescing and shield-layer design to dramatically reduce origin load during traffic spikes. We implement stale-while-revalidate and stale-if-error strategies to protect your backend.
Custom request routing, A/B traffic splitting, and geo-aware caching rules — implemented cleanly at the edge without black-box vendor tooling you can't inspect or debug.
02 / Reverse Proxying
Purpose-built reverse proxy software that does exactly what your infrastructure needs — from simple TLS termination and load balancing to complex request transformation and backend routing.
We build lightweight, focused reverse proxy software in Go or C — no Nginx plugin archaeology, no Envoy YAML sprawl. A proxy that does your specific job and nothing else.
Automated certificate provisioning, renewal, and multi-domain TLS handling — integrated cleanly into your proxy layer without third-party dependencies.
Active and passive health checks, configurable backend selection strategies (round-robin, least-connections, weighted), and graceful failover — all observable and debuggable.
Header manipulation, URL rewriting, payload inspection, and rate limiting — implemented at the proxy layer where it belongs, not scattered across application code.
03 / Data Caching
Caching solutions for the data layer — reducing database load, speeding up API responses, and ensuring your application handles traffic spikes without degrading under pressure.
Architecture and implementation of in-process or sidecar in-memory caches — LRU, LFU, and TTL-based eviction policies designed around your actual data access patterns.
Integration and tuning of distributed caching tiers (Redis, Valkey, Memcached) — connection pooling, serialisation strategies, and cache-aside pattern implementation done right.
Strategies for maintaining consistency between your cache and source of truth — write-through, write-behind, event-driven invalidation — matched to your consistency requirements and team's operational capabilities.
Identifying and caching expensive database queries, API aggregations, and computed results at the right layer — reducing latency and database load without introducing correctness risks.
The process
We study your traffic patterns, infrastructure, and pain points — no assumptions, no off-the-shelf templates.
We design the caching architecture and agree on the specification with you before writing a single line of code.
We build and benchmark against your real workload in staging until the numbers — and confidence — are right.
We deploy to production alongside you and remain available for monitoring, tuning, and ongoing iteration.
Why Nordic
Nordic software engineering has a quiet reputation for reliability over hype. We carry that ethos into every engagement — small, focused teams with deep expertise, no venture-backed pressure to ship features that don't serve you.
We work with clients across Scandinavia and Northern Europe, and remotely with organisations that share our values: precision, transparency, and the long view.
Tell us what you're building. We'll tell you where we can help, honestly — even if that means pointing you somewhere else.
