AI and machine learning
Recommendation engines, computer vision, NLP pipelines, and the production engineering that makes models actually useful. We've shipped ML for health tech, media platforms, and search systems.
Technical consultancy
We fix hard problems in AI, infrastructure, and security.
Spectral Blade is a hands-on engineering consultancy for founders and product teams. We build AI systems, rescue compromised infrastructure, and deliver the backend work that keeps revenue-critical products running.
What we do
Three areas. One accountable team.
Backend and growth systems
Analytics pipelines, A/B testing infrastructure, API design, and the plumbing behind high-traffic products. We instrument what matters and make it reliable.
Security and technical rescue
Compromised servers, malware removal, vulnerability assessment, and hardening. When something is broken or breached, we diagnose it fast and fix it properly.
Selected work
Recent engagements.
Growth and AI
Hulkshare
High-traffic consumer media platform.
- Built an automated thumbnail selection tool to improve content presentation and click-through rates.
- Developed recommendation and search systems using LLMs to improve metadata quality and discovery.
- Delivered backend analytics for traffic, CTR, and A/B testing.
- Helped screen and hire engineers as the team grew.
Applied ML
Bloods.ai
Health technology startup.
- Built machine learning models for detecting analyte concentration in blood using FTIR spectroscopy.
- Bridged the gap between research and deployment under real-world signal and hardware constraints.
Security rescue
Scientu.net
Compromised WordPress site with active malware.
- Identified vulnerable plugins enabling remote code execution on the backend.
- Removed malware, crypto-mining processes, and backdoors. Rebuilt WordPress core where needed.
- Replaced insecure plugins, hardened the server, and prevented reinfection.
Testimonials
What clients say.
"Spectral Blade quickly identified a far more serious issue than we expected, carried out a full investigation, removed malware and crypto-mining processes, cleaned up backdoors, replaced insecure plugins, and locked down the server. They were proactive, thorough, and left the site in a much safer state."
"Spectral Blade consistently adapted to unconventional problems in the field of LLMs, helping us improve video metadata and search algorithms. They quickly grasped complex concepts, delivered thoughtful solutions, and were a key asset to the team."
How we work
Start small. Go deeper when it makes sense.
Audit
A short, paid diagnostic to understand the stack, find the real problem, and define a clear path forward.
Deliver
Fixed-scope implementation. We build, fix, or ship what was agreed, with senior engineers doing the actual work.
Retain
Ongoing support: architecture review, hiring help, hands-on work, and a technical partner you can call on.
About
Small team. Senior work.
George Sandle leads Spectral Blade. Background in AI research engineering, with production experience across machine learning, backend systems, experimentation infrastructure, and security remediation.
The model is intentionally lean. You work directly with a senior engineer, not a sales layer. When an engagement needs deeper specialist support, we bring in trusted collaborators from a network we've built over years of shipping together.
What you get
Fast diagnosis, honest assessment, and engineering work that actually ships. No decks, no fluff.
Good fit
Founder-led companies, product teams with systems that need to work, and anyone dealing with a technical problem they can't ignore.
