We rebuild the systems you cannot take offline.
NEFELOMA is a backend engineering consultancy in Athens, Greece. We take on the work that is hard to staff: the migration nobody wants to own, the system that has to change while it stays in production, the architecture that needs deciding.
We are led by Panagiotis Siatras, who has spent 20+ years rebuilding the systems most people would rather not touch. See the work →
You may have used our work if you have secured infrastructure with Smallstep, deployed on Fly.io, hosted a site with Pagely (now GoDaddy), or ridden a Spin scooter.
How we work
We keep the backend boring, and we say it with pride. Boring is predictable, predictable is reliable, and reliable is the whole job. If two or three components can do it well, with performance and failure handled, we will not add a fourth just to look clever.
Simple wins. We cut a problem down to the bone, then design the solution back up from there.
Boring does not always mean off-the-shelf. When a product on the market would fight the system more than it serves it, the simpler choice is a small, purpose-made piece that fits exactly: less to run, not more, because it does one thing and stops there. More than once, what we built that way was solid enough to have shipped as a product of its own.
What we do
Live migrations
Porting platforms, swapping data layers, re-architecting live systems. We do it incrementally, with no big-bang cutover and no taking you down.
Distributed systems at scale
Designing and scaling the services that carry real load. We build in Go, lean on Postgres & Redis, and keep the moving parts as few as the problem allows.
Architecture and direction
Owning the shape of a system: the contracts, the boundaries, the substrate every other team builds on. The decisions that are expensive to get wrong.
Reliability and observability
Instrumentation, data retention, capacity. The unglamorous work that keeps a system honest when traffic spikes and things fail.
