Engineer-led studio for applied AI/ML and technical SEO
We build the tools we actually use.
Engineer-led studio for applied AI/ML and technical SEO — one team, both disciplines. We ship RAG, LLM apps and agents, and semantic search on big data, plus the structured data and Core Web Vitals that make it findable: built, served, and monitored on AWS and Google Cloud. The proof is already installable.
- Applied AI/ML on big data — RAG, LLM apps, embeddings/semantic search, and monitored model serving (MLOps) on AWS and Google Cloud
- Code + technical SEO under one roof — recommendations that actually ship, not another PDF
- Direct engineer access. No account managers, no buzzword soup.

Most digital work looks done long before it actually works.
A site can pass design review and still load in four seconds on a real phone. Schema can validate and still never earn a rich result. We start where the problems actually are — in the code, the crawl, the structured data Google reads — and let the design and marketing sit on something solid.
Built on a modern, maintainable stack — documented architecture engineers can inspect.

AI & ML / Big Data
RAG and retrieval, LLM apps and agents, embeddings and semantic search, and applied ML on large datasets — trained, served, and monitored (MLOps) on AWS and Google Cloud. We get models past the notebook and into production.
Fintech & Legal CRM
Custom CRM for fintech and law firms — reach and process customers faster, with compliance and audit trails built in from the first commit.
Cloud & Data (AWS · GCP)
Data pipelines, serverless, and scalable infrastructure on AWS and Google Cloud — built to stay fast and cost-aware as volume grows.
Adtech & Publishing
Publisher platforms, ad ops, and programmatic SEO that survive a traffic spike instead of collapsing the first time everyone arrives at once.
Mobile Apps
React Native and native iOS/Android, from a tight MVP through to a production app that holds up under real load.
Security & Compliance
Secure SDLC, OWASP remediation, and the groundwork for SOC 2, PCI DSS, and ISO 27001 — security as a design input, not theater at the end.
Proof, not slideware
Don’t take our word for it. Install it.
Schema Preview is our structured-data validator. It inspects any page’s schema.org markup and tells you what’s valid, what’s broken, and what won’t show in search. Free, live on Chrome and Firefox, and built by the same people who’d build your project.

How we work
You talk to the people who write the code.
No account-manager relay. No offshore black box. We scope tightly, ship in small increments you can see, and write the structured data and tests as we go — not as a cleanup pass at the end.
- Scan
We run Schema Preview and a fast technical pass on your live site, surfacing broken or missing structured data and the pages quietly losing rich-result eligibility.
- Score & prioritize
You get a one-page scorecard, then a fix backlog scored by impact vs. dev effort—written so engineers can act, not just marketers.
- Ship the fix
We implement in your codebase against clear acceptance criteria, with performance and accessibility targets baked in. Milestone-based, fixed timeline.
- Verify & hand over
We validate rich-result eligibility, confirm the wins in the SERP, and hand over docs, tests, and infra-as-code. Continue on retainer or call us when you need us.
Live self-proof
This page is the portfolio piece.
An engineer-led agency should ship a fast site. This one is static, sends almost no JavaScript, and is built to score near-perfect on Core Web Vitals — measured, not asserted. If our own site cut corners, why would you trust us with yours?
0 render-blocking JS frameworks, 47 schema.org types our tool validates, and 2 browsers it ships on, today.
Our products
We ship products, not just proposals
