DDCode — Data-Driven Code
We build the tools we use.
Engineer-led digital agency. Code and technical SEO first — design and marketing after. We ship high-performance AI/ML on big data, CRM and platforms on AWS and Google Cloud, and our proof is already on the Chrome Web Store.
- AI & ML on big data, fintech & legal CRM, adtech, mobile, and security — built 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.
Specialties
Where we go deep.
AI & ML / Big Data
High-performance AI and ML applications that process big data and content at scale — trained, served, and monitored on AWS and Google Cloud.
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.
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?
- 0render-blocking JS frameworks
- 47schema.org types our tool validates
- 2browsers it ships on, today
What we do, in full
Code-first, search-aware, end to end.
Technical SEO
Crawlability, indexation, rendering, architecture, and Core Web Vitals — the unglamorous work that decides whether anything else in search lands.
Search & structured dataStructured data & schema
JSON-LD done properly: implemented, validated, and checked against what Google actually displays. This is our signature.
Search & structured dataGEO & 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.
BuildWeb 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.
BuildAI & ML engineering
High-performance AI and ML applications that process big data and content at scale — built, served, and monitored on AWS and Google Cloud.
BuildCloud & DevOps
Scalable, cost-aware infrastructure on AWS and Google Cloud — data pipelines, serverless, CI/CD, and observability.
GrowGrowth & growth hacking
Growth engineering and growth hacking: rapid experiments, funnel optimization, and analytics wired to product events — measurable acquisition, not vanity metrics.
BuildMobile app development
React Native and native iOS/Android, from a tight MVP through to a production app that holds up under real load.
SpecialtiesFintech & 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.

SpecialtiesSecurity & compliance
Secure SDLC, OWASP remediation, and the groundwork for SOC 2, PCI DSS, and ISO 27001 — built into the process, not bolted on.
