Python / AI engineer — offline RAG, CAD/GIS automation, LLM agents
I build systems that work without internet — and prove their work with tests, measured latency, and evidence links.
Currently a medical-equipment engineer at a radiotherapy center; leaving in November to do software full-time.
Field service, 2022—2026 · linear accelerators
01 / Service record
Available full-time from late November 2026 · Mogilev, Belarus · UTC+3
Maintenance of Varian TrueBeam and VitalBeam linear accelerators: dosimetry checks, MLC and imaging calibration, fault diagnosis in an RF-shielded bunker, service documentation with no margin for error.
A commercial geodetic converter, a production photo-to-DXF pipeline for surveyors, an offline RAG system for equipment documentation, and a live Telegram product on Cloudflare.
Leaving the clinical role to build software with the same constraint I worked under for four years: the result has to be verifiable.
02 / Selected work
Results: What is public.
Offline RAG over radiotherapy equipment documentation. Hybrid LanceDB + BM25 retrieval, local embeddings and reranker, CPU-only. Answers cite document, page and drawing region.
Computer-vision pipeline that turns a photo of a hand-drawn survey sketch into a topographic DXF. Marker detection, OCR, block library. Cuts manual drafting from 4 hours to 15 minutes.
Commercial desktop product for sub-millimetre conversion between legacy local coordinate systems and WGS-84. Four-stage numerical calibration, round-trip validation, hardware-locked licensing.
03 / What I do
01
Document ingestion, hybrid retrieval, reranking, local quantized inference (llama.cpp / GGUF, ONNX), evaluation harnesses, evidence-linked answers.
02
DXF/DWG generation, photo-to-drawing CV pipelines, coordinate systems, numerical calibration, desktop tooling with PySide6/PyQt6.
03
FastAPI services, async pipelines, SQL schemas and migrations, Cloudflare Workers/D1/R2, CI with coverage and mutation gates.
04 / About
I am a medical-equipment engineer at the Mogilev Regional Oncology Dispensary, where I maintain Varian TrueBeam / VitalBeam linear accelerators. That work is safety-critical and documentation-heavy — which is exactly why I built Engineer Companion: a field engineer in an RF-shielded bunker needs the exact page in seconds, with no internet.
I have been building software alongside that role since 2020: a commercial geodetic converter, a production photo-to-DXF pipeline, an offline RAG system, and a live Telegram product. I am leaving the clinical role in November 2026 to work on software full-time.
Commercial projects are covered by NDA. I can show architecture, screenshots, and measured results; source stays private.
Looking for a remote Python/AI role in CAD/GIS automation, RAG/LLM systems, or medtech. I can start full-time from late November 2026.
