Engineering consulting

Software, built with intention.

Heart & Fire is a small engineering studio that helps founders and teams take products from idea to shipped, every decision made with care, every line of code earning its place.

What we do.

A focused set of engagements, sized to match where you are, from a single architectural review to a full zero-to-one build.

i.

Zero-to-one builds

Turn a sharp idea into a real product. Architecture, build, and launch, owned end-to-end on a stack chosen for the long run.

ii.

Product engineering

Embed alongside your team to ship features, harden infrastructure, and turn a working prototype into a product people trust.

iii.

AI & LLM integration

Practical AI features, retrieval, extraction, voice, agents, built on the model providers and tooling that actually fit your product.

Advisory & consulting

Architecture reviews, hiring help, fractional CTO, and an honest second pair of eyes. Short engagements that save long, expensive detours.

How an engagement moves.

Every project is different, but the shape is the same: understand the problem deeply, build the smallest honest thing, and refine from there.

Phase 00
Discovery

A short, focused conversation about what you're building, what's working, and what isn't. We leave with a shared understanding of the problem and a candid recommendation for the path forward.

Phase 01
Foundation

Set the technical bedrock. Stack decisions, data model, auth, infrastructure, the parts that quietly determine whether the product can grow into itself a year from now.

Phase 02
Build & refine

Ship in tight loops. Every week the product gets a little sharper, the feedback gets a little richer, and the next decision gets a little easier.

Phase 03
Launch & handoff

Polish the public surfaces, ship to the store or the web, and leave behind documentation a future engineer will thank us for. The goal is never just to launch, it's to leave something maintainable.

What we believe.

A short list of convictions that shape every decision, from the stack we choose to the way we write a commit message.

i.
Listen first, code second

The best technical decisions start with an honest understanding of the people the product is for. Software is downstream of clarity.

ii.
Small things, shipped often

A tight loop beats a grand plan. Weekly shipping forces honesty and creates the feedback that good products are built from.

iii.
Boring tools, on purpose

We pick the stack that will still be a good idea three years from now. Novelty is reserved for the parts of the product that earn it.

iv.
Leave it better than we found it

Every engagement ends with code your team can read, infrastructure your team can run, and decisions your team can defend.
