What I've built
Real systems in production, built solo · each solves a sales or decision problem with data and LLMs.
B2B lead engine (RO company data)
End-to-end platform across 16+ Romanian data sources (ANAF, risco.ro, ONRC, VIES, TERMENE, Google Maps): automated discovery, enrichment, scoring and qualification of companies for B2B sales. It replaces a week-long manual process with an engine that grinds through thousands of firms a day, fully unattended.
- ▪ 10,000 firms/day · 1 proxy account
- ▪ 8,307 firms · 99% coverage
- ▪ 1,000 pre-qualified leads/day
SMC + Divergence Suite · TradingView (Pine v6)
Pine Script v6 indicators and screeners for TradingView, built on Smart Money Concepts (a LuxAlgo SMC fork): Order Blocks, BOS, CHOCH, Fair Value Gaps and HTF bias, with multi-pair alerts. A separate TD 9+13 plus multi-indicator divergence line, validated through a Python backtester on BTCUSDT 15M.
- ▪ Python backtester on BTCUSDT 15M, 2017-2026 (299k bars), TV parity
- ▪ Multi-pair screener across dozens of symbols, 17-pair chunks
- ▪ SMC detectors: Order Blocks, BOS, CHOCH, FVG, HTF/MTF bias
Local Qwen - $0 Local-LLM Nightly Pipeline
A personal nightly pipeline that runs a local LLM (Qwen3.6-35B-A3B on a local GPU) at zero cost overnight. A cron orchestrator walks a 42-job advisory DAG (memory/rules, lessons mining, source scanning, REPA dossiers, code-health audits), all strictly advisory: nothing auto-publishes.
- ▪ 42 jobs in the nightly DAG, 56 scripts
- ▪ Qwen3.6-35B-A3B, IQ4_XS quant, 256K-token context
- ▪ 4,200+ reports generated; $0.05-0.15/night
Prediction-market monitor + paper-trading scanner
A read-only research stack that monitors prediction and perpetuals markets and tests copy-trading strategies purely on paper (DRY-RUN), with no funded wallet. It spans Polymarket, Hyperliquid, dYdX v4 and GMX under one protocol: whale discovery, strict qualification, fee modeling and out-of-sample backtests.
- ▪ 90 Python scripts across 4 venues (Polymarket, Hyperliquid, dYdX v4, GMX)
- ▪ 60/40 out-of-sample backtest; dYdX v4 copy cleared the OOS gate
- ▪ $0 real risk, all paper/DRY-RUN; self-monitor caught a 38h failure
Fully-local two-way voice assistant ($0/mo)
A fully-local voice assistant on Windows, zero cloud cost: mic → STT (faster-whisper) → free LLM (NVIDIA NIM) → TTS (Piper). It answers out loud in 1-3 sentences, with wake-word gating, barge-in and anti-hallucination guards; PyAudio-free, it runs on Python 3.14 and can drive a live Claude Code session.
- ▪ 400-600ms round-trip when warm, 1s to first audio
- ▪ $0/mo operating cost (STT, LLM and TTS local/free)
- ▪ LLM pinned to gpt-oss (0.6s) vs 3.4s default lane
The Website Factory
An end-to-end system that turns Romanian SMBs with no website into clients: discovery from public registries and Google Maps, a need × reachability score (0-100), a per-prospect mockup on a preview URL, and 7-day delivery. Built on a bilingual Astro template with Decap CMS, shipped on Cloudflare Pages.
- ▪ About 100 per-prospect mockups for real businesses (Iași, Cluj, Timișoara, Sector 1)
- ▪ Need × reachability scoring 0-100, from the web gap
- ▪ Fixed 2,000 RON, 7-day delivery; 0 EUR/mo on Cloudflare
