If you've landed on my profile, you're probably a founder, CTO, or senior engineer
looking for one of three things:
- Deep technical content on SaaS, React, Node.js, and cloud architecture
- A senior developer or Fractional CTO to work with on a US-market product
- Both
Either way, welcome. Let me give you the quick picture.
What I Do
I'm a freelance full-stack developer and Fractional CTO specializing in
SaaS products, API architecture, and cloud infrastructure for the US market.
Over the last several years I've shipped 100+ products across:
SaaS platforms: Multi-tenant architecture, Stripe billing, auth systems,
role-based access, usage metering
API development: REST APIs built API-first, versioned, documented,
and built to handle US enterprise scale
Cloud infrastructure: AWS and Vercel deployments, Supabase backends,
Terraform, zero-downtime CI/CD pipelines
AI integration: LLM-powered features, RAG systems, async AI processing
built into production SaaS products
Regulated industries: HIPAA-compliant healthcare apps, PCI DSS FinTech
products, FERPA-compliant EdTech platforms
My clients are typically US-based startups from pre-seed through Series B,
and enterprise teams that need senior technical leadership without the
overhead of a full-time hire.
My Stack
Frontend -> React, Next.js, TypeScript, Tailwind CSS
Backend -> Node.js, Supabase, PostgreSQL, Redis, REST APIs
Cloud -> AWS, Vercel, Docker, Terraform, GitHub Actions, CI/CD
AI -> OpenAI, LangChain, vector databases, RAG architecture
What I Write About Here
I publish practical, code-heavy articles aimed at developers building
serious products, not toy examples.
Topics I cover regularly:
Node.js architecture: performance, clustering, worker threads,
memory management at scale
SaaS engineering: multi-tenancy, billing models, feature flags,
pricing schema design
TypeScript in the real world: strict mode, Zod validation,
discriminated unions, utility types at scale
API design: REST structure, versioning, contract testing,
OpenAPI-first development
Cloud and DevOps: AWS and Vercel deployment patterns, Supabase
architecture, GitHub Actions CI/CD without a DevOps team
AI integration: practical LLM patterns, RAG, async job queues
for AI features in production SaaS
Regulated tech: HIPAA, PCI DSS, FERPA and what they actually
require from developers, not lawyers
No padding. No "in this article we will explore." Just the patterns,
the code, and the reasoning behind both.

Working Together
If you're building a SaaS product, scaling a Node.js backend,

a senior technical voice in the room without hiring a full-time
CTO, that's exactly the kind of work I take on.
US clients, UK clients, remote. I've done all of it.
