Production automation for messy, real-world business processes.
I turn manual operations into reliable software — inconsistent documents, unreliable workflows, regulated industries. From RPA engines and workflow orchestration to AI-powered document pipelines, across accounting, energy, and finance in Romania and the UK.
Projects
Co-founder and CTO — responsible for all development and infrastructure. Rinkt automates manual business operations for accounting firms, distributors, and back-office teams. Implementation-first: conversational workflow builder, orchestration API, and a cross-platform runner executing across browsers, desktops, and Office apps — with durable execution that recovers mid-step, not from scratch.
Accountants spend hours matching bank transactions to accounting codes by hand. This tool parses statements from 9 Romanian banks, classifies transactions with GPT-4, and surfaces edge cases for human review — turning hours of manual work into minutes.
Instant search across 4M+ Romanian companies with live ANAF financial data. Free, open source, runs entirely on Cloudflare's free tier.
Desktop apps that auto-update need to not brick themselves. Open-source Go library that manages crash-safe updates: external supervisor pattern, versioned directories, automatic rollback on failure.
Markdown viewer with AI session tracking. Single Go binary, installable via npm or Homebrew.
DNS forwarding and caching proxy from scratch — wire protocol parsing, local zones, TTL-aware cache. A deep dive into networking fundamentals with async Rust.
Client Engagements
Production systems delivered for clients in energy, finance, and e-commerce — from single-developer POCs to multi-year team engagements.
Started as a single-developer POC, grew to a team of 8 over 7 years. Built aggregation software for solar farms totalling 5GW, direct dispatch on negative energy prices with real-time notifications, and command & control for gas turbines producing 800MW+. Deployed software and hardware for frequency containment reserves across sites in France and Spain. Owned CI/CD, service deployment, SFTP configuration, and Helm charts.
A Romanian energy distributor routes thousands of customer and partner emails manually across 212 internal categories. Built an ML pipeline using SVM and TF-IDF that classifies incoming emails and extracts structured rules — trained on 36K historical messages, now progressing toward production deployment.
Product returns arrive as unstructured emails — PDFs, photos, inconsistent formats. Built a pipeline that extracts data via OCR, classifies issues with GPT-4o, matches products using vector similarity, and routes by confidence: auto-approve, review, or escalate.
UK finance brokers manually check rates across 10+ funders. Built parallel browser and API workers that query all funders and return unified quotes — replacing a 30-minute manual process.
