What I Do

Services That Move the Needle

I don't just write code. I make technical decisions that align with your business goals, timeline, and budget.

MVP Architecture & Delivery

Go from idea to live product in weeks, not months. I design lean architectures that ship fast and scale when you need them to.

  • Technical feasibility assessment
  • Stack selection & architecture design
  • Hands-on development & deployment
  • Launch-ready in 4-8 weeks

Technical Strategy & Roadmap

CTO-level guidance without the CTO salary. I help you make the right technical bets and avoid costly rewrites.

  • Technology stack evaluation
  • Build vs. buy decisions
  • Vendor & API integration strategy
  • Engineering team hiring & onboarding

Cloud & Infrastructure

Right-sized cloud architecture that doesn't bleed money. From Firebase MVPs to Kubernetes at scale.

  • GCP / Firebase / AWS setup
  • CI/CD pipelines & DevOps
  • Docker & Kubernetes orchestration
  • Cost optimization & monitoring

AI & Automation Integration

Integrate AI where it actually creates value. Not hype-driven, but ROI-driven AI adoption for your product.

  • AI-powered product features
  • Search & recommendation engines
  • Process automation & workflows
  • LLM integration & prompt engineering

Full-Stack Product Engineering

End-to-end product development across web, mobile, and backend. Multi-tenant SaaS, marketplace platforms, and complex integrations.

  • React / Next.js / React Native apps
  • NestJS / FastAPI microservices
  • Payment, auth, & third-party integrations
  • Multi-tenant & multi-language support

Technical Due Diligence

Evaluating a startup for investment or acquisition? I assess code quality, architecture, scalability, and technical debt.

  • Codebase & architecture audit
  • Scalability & security assessment
  • Technical debt quantification
  • Team capability evaluation

How I Work

From Call to Launch

01

Discovery

We talk about your business, users, and constraints. I assess technical feasibility and identify the fastest path to value.

02

Architecture

I design a lean, scalable architecture. Stack selection, data modeling, API design, and deployment strategy — all documented.

03

Build & Ship

Rapid, iterative development with weekly demos. You see progress every week, not just at the end.

04

Handoff & Scale

Clean code, documentation, and knowledge transfer. I help you hire your first engineers and set up processes that last.

Get Started

Let's build something
worth shipping.

Whether you need a fractional CTO to steer technical strategy, a hands-on engineer to ship your MVP, or an audit of your existing tech — I'm one call away.
