About Us

Who We Are

Software for data teams. That's it. That's the whole pitch.

Sigflux is a software company.If your problem involves data that needs to be collected, stored,processed, or made useful, we're a good fit.We build internal tools, data pipelines, and backend APIs.

Our Values

What we care about

Reliability

Data systems fail in weird, quiet ways. So we build with error handling and observability from day one. Not as an afterthought.

Simplicity

The best systems feel obvious. We reduce moving parts, keep interfaces predictable,and make future changes easy without rewriting everything.

Ownership

We don't just write code and disappear. We stick around. If something breaks at 2am, that's on us to fix.

Features

What we bring to the table

Data validation layers

Internal dashboards

RESTful API design

ETL & ELT pipelines

Database design

Monitoring & alerting

Production-grade APIs

Authenticated, versioned, documented, and tested under load before they go live. No surprises in production.

Schema enforcement

Every pipeline has validation checkpoints. Bad data gets caught early, not after it's already messed up everything downstream.

Batch & stream processing

Data arrives in bulk, in real time, or both. We handle all of it.

Data transformation

Raw data is messy. It never shows up the way you need it. We clean it, reshape it, and make it useful.

Low-latency systems

When milliseconds matter, we optimize at every layer. Connection pooling, caching, efficient queries. The usual suspects.

Tested & documented

Everything we ship comes with tests and docs. Your team should be able to pick it up and run with it.

F.A.Q

Frequently Asked Questions

What kind of companies do you work with?

Anyone with a data problem. Startups building their first API, established companies drowning in legacy pipelines... If your challenge involves data, we're interested.

What technologies do you use?

R, Rust, JavaScript, and SQL (postgres, sqlite). R is themain one. We use it for backend services, dataprocessing, and web apps. Rust and JS fill in wherethey're the better fit. We pick tools deliberately,not by hype.

Do you only build new systems, or can you fix existing ones?

Both. Not everything needs a ground-up rewrite. Sometimes the best move is making what you already have faster, more reliable, or just... less painful to work with.

How does a typical engagement work?

We talk, figure out what you need, agree on what we'll deliver, and get to work. No 47-slide decks. We ship incrementally so you see progress the whole time.

Do you stick around after delivery?

Yes. We offer retainer-based support for systems we've built. Monitoring, bug fixes, improvements. We can also train your team to take over if you'd rather bring it in-house.

How do you handle data security?

Least-privilege access, encryption in transit and at rest, and we work within whatever compliance requirements you already have. Happy to sign NDAs before anything starts.
