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.

Specialties

Where we go deep.

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.

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.

  1. 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.

  2. 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.

  3. Ship the fix

    We implement in your codebase against clear acceptance criteria, with performance and accessibility targets baked in. Milestone-based, fixed timeline.

  4. 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

Schema Preview is a free structured-data validator for Chrome and Firefox that we run on every client project — install it before you ever talk to us. NeckGuard is a posture coach that reads head motion from compatible headphones and gives you one gentle nudge, no pausing your music.

Live session screen showing a green check for good posture, the head tilt indicator, session time, good-posture streak, nudge count and estimated neck load.

NeckGuard reads head motion from the AirPods or Beats you already wear. Look down too long and it dims your audio for a moment, plays one soft cue, and gets out of the way. Your music keeps playing.

  • Calibrate once, in a few seconds
  • One gentle nudge, never a pause
  • Posture score, streaks and trends

What we do, in full

Code-first, search-aware, end to end.

Search & structured data Technical SEO Crawlability, indexation, rendering, architecture, and Core Web Vitals — the unglamorous work that decides whether anything else in search lands. Search & structured data Structured data & schema JSON-LD done properly: implemented, validated, and checked against what Google actually displays. This is our signature. Search & structured data GEO & AEO (AI search) Getting cited in Google’s AI Overviews, ChatGPT, and Perplexity. The substrate is the structured data and entity clarity we already specialize in. Build AI & ML engineering RAG, LLM apps and agents, semantic search, and ML model serving on big data — trained, served, and monitored on AWS and Google Cloud. Past the notebook, into production. Build Web development SEO-friendly web apps in Astro and Next.js, headless CMS, SSR, and API integration — with schema and performance built in from the first commit. Build Cloud & DevOps Scalable, cost-aware infrastructure on AWS and Google Cloud — data pipelines, serverless, CI/CD, and observability. Grow Growth & growth hacking Growth engineering and growth hacking: rapid experiments, funnel optimization, and analytics wired to product events — measurable acquisition, not vanity metrics. Build Mobile app development React Native and native iOS/Android, from a tight MVP through to a production app that holds up under real load. Specialties Fintech & Legal CRM Custom CRM for fintech and law firms, plus payment and RegTech work — reach and process customers faster, with compliance built in from the first commit. Specialties Adtech & publishing Publisher platforms, ad ops, and programmatic SEO designed for the traffic spike — not the average day.
