Available for new projects

Product engineering,
without the overhead.

Substrate is a boutique engineering studio led by two co-founders who ship full-stack products, integrate AI into production systems, and architect infrastructure that holds up under pressure. No agency overhead. No middlemen. Just engineers who build.

CAPABILITIES

What we build.

Six disciplines. Applied together when your product needs it.

Full-stack product engineering

From database schema to UI component. We design and build complete product systems, not just features. TypeScript, React, Next.js, PostgreSQL, all production-grade from day one.

Next.jsReactTypeScriptNode.js

AI integrations & systems

LLM pipelines, embeddings, retrieval systems, and structured outputs. We build AI that ships to production: evaluated, monitored, and observable. Not proof-of-concepts.

OpenAIAnthropicRAGLangChain

Automation workflows

Complex business logic encoded as reliable, observable pipelines. Trigger-based, event-driven, or scheduled. Your team gets leverage, not more manual work.

n8nInngestTemporalQueues

Backend architecture

APIs, queues, caching layers, and job workers designed for the scale you're heading to, not just where you are today. Built to be maintained, not just launched.

PostgresRedistRPCREST

Scalable SaaS infrastructure

Multi-tenancy, billing, auth, feature flags, rate limiting, audit logs. The table stakes of a production SaaS, done properly and without shortcuts.

StripeAuth.jsSupabaseVercel

0→1 MVPs

From validated idea to working product. We move fast without cutting corners, shipping real software that founders can demo, sell, and iterate on.

HOW WE WORK

No theater. Just engineers.

A process that respects your time and produces working software.

Discovery

30 minutes

One call. We map your scope, constraints, and success criteria. We ask hard questions about timelines, existing systems, and what "done" actually means for your business.

No NDAs required to start. We respect your time.

Spec & Proposal

2-3 days

A clear technical specification with architecture decisions, a realistic timeline, and fixed pricing. No bloat. No ambiguity. You know exactly what you're getting before we write a line of code.

Proposals are precise. Prices are fixed.

Build

Weekly cadence

Weekly demos. Daily deploys to staging. Async-first communication, no standups for the sake of standups. You see real, working software from week one, not mockups.

You have access to the repo from day one.

Ship

Production deploy

Production deploy, monitored, with full documentation and a handoff session. You own everything: code, infrastructure, credentials. No lock-in, no ongoing dependency.

Clean handoffs. Full ownership transferred.

We take on a limited number of projects to maintain quality and focus. Projects are booked in advance. Availability is limited by design.

THE TEAM

Founded by engineers.
Built to ship.

An engineering-first studio. We bring deep technical expertise and a founder's mindset to every product we build.

Saksham

Co-founder

Backend-focused full-stack engineer with experience at a YC-backed startup and US-based startups. Builds reliable APIs, scalable infrastructure, and production systems that stay up. Drives technical execution from architecture to deployment, moving fast without sacrificing quality.
