ENGINEERING
CONSULTING
FOR R&D.

We help scientific and engineering teams move from legacy code to modern stacks — Python, embedded firmware, event-driven backends.

By an engineer with 20+ years across power systems, embedded hardware, and scientific software.

● What you get
  • → Working code, not slide decks
  • → One senior engineer, hands-on
  • → Tests, CI, docs to scope
  • → Short, well-scoped engagements
  • → Honest no when it isn't fit
● Who runs this

SOLO PRACTICE

20+ yrs across power systems, embedded, scientific Python. Based in Tolmin. Works in English & Slovenian. Small roster on purpose.

● SECTION / 02 — What we do

FIVE THINGS
WE DO.

Project-based engagements. Hands-on. You get working code, not slide decks.

↑ Pick one. Or two. We compose.
01

MATLAB → Python migration

Any math, any domain. Audit, risk matrix, pilot module, full migration. From science to production-grade Python with proper testing and CI.

02

Power-systems algorithms

State estimation, OPF, transient stability, short-circuit analysis. Custom development in Python with pandapower, PowerFactory API, and proprietary solvers.

pandapower PowerFactory PyPSA GridPACK Coming soon
03

Embedded BLE devices

ESP32 · nRF52 · Zephyr RTOS. From prototype to production-ready firmware. We build our own FlyBeeper paragliding devices — we know this stack in production.

nRF52 Zephyr ESP-IDF KiCad OTA DFU Coming soon
04

Backends for IoT/BLE fleets

FastAPI, NATS, MQTT, event-driven architecture. For hardware teams that need a reliable, scalable cloud side without hiring a full backend team.

FastAPI NATS MQTT Postgres TimescaleDB Coming soon
05

R&D advisory

Algorithm prototyping, technical due diligence, scientific Python coaching. Short paid engagements that prove fit before scaling. No PowerPoint consulting.

● SECTION / 04 — Who we are

SMALL
PRACTICE.
SLOVENIA.

Alpisto is a small engineering practice based in Slovenia. We focus on the technical problems that sit between research code and production systems — the gap where scientific computing meets real-world constraints.

We work hands-on. Every engagement is led by a senior engineer, not delegated to juniors. Our own product line, FlyBeeper — seven BLE wearables for paragliding pilots — is proof that we ship hardware, firmware, and backends together in production.

We prefer short, well-scoped engagements that prove fit before scaling. If the problem is interesting and the timeline is realistic, we want to hear about it.

YOU'RE BUILDING.
