On-device NPU inference engine — AMD Ryzen AI (XDNA2), Linux

From-scratch engine running whole model graphs natively on the laptop NPU via the open MLIR-AIE / IRON stack — where the prior open-source high-water mark was a single matmul at ~0.6% utilization and AMD’s own Linux stack offloads zero ops. 16 models across 11 architectures (BERT · Whisper/Parakeet/GigaAM · ViT/DINOv2/ResNet-18/CLIP · ESM-2), parity ~4e-3. Core: fuses a 12-layer decode into one NPU dispatch (72→1 per token), weights + KV resident. −29% energy / ~half the package power vs CPU at equal accuracy (WER 0.117). Making it compile at scale meant fixing AMD’s compiler & operators upstream.

AI payroll-compliance agent over 1С:ZUP

For a top-3 Russian B2B accounting-software publisher. Daily-reconciliation AI agent on the dominant Russian payroll/ERP platform + a Go/Rust MCP server; 30+ validation-rule registry, tax/labor-regulation cross-references, on-premise connector. Closed-beta with real client accountants surfaced specific compliance discrepancies in 10+-year ERP legacy.

Document-intelligence pipeline for accounting primaries

Self-hosted OCR → LLM extraction of structured fields from Russian accounting primaries, PII kept on-premise (dots.ocr on H100 + an LLM extraction stage). Built a gold-set, a human-in-the-loop labeler and a scorer, then benchmarked OCR→LLM architectures on it — quantifying the privacy-vs-accuracy tradeoff to choose the production design on ground truth, not impression.

kde-mcp — computer-use MCP for the Linux desktop

The kind of tool Anthropic’s computer-use covers for macOS/Windows, still rare on Linux/Wayland — built from scratch, solo. Drives apps through the accessibility tree (like a screen reader) rather than pixel-clicks: more reliable and safer. Safety policy gate, ADR-documented.

Multi-tenant medical SaaS — OCR + LLM PII depersonalization

Local PaddleOCR-VL + Presidio + LLM-based PII detection for Russian PII (SNILS / INN / passport) with bounding boxes; per-tenant isolation (nginx routing) + a ClickHouse dedup buffer in front of Postgres.
