I turn messy manual processes into clean automated systems — agents, scrapers, bots, and APIs that work while you sleep. I care about delivery speed, system stability, and ROI you can actually measure.

§ 01 — Services

Four ways I replace manual ops with code.

S · 01

AI Agents & RAG pipelines

Production agents on top of GPT-4, Claude, and open models. Retrieval over your docs, tools, APIs — answers that are actually grounded, logged, and auditable.

S · 02

Backend & API systems

FastAPI and Flask services with PostgreSQL, auth, Stripe/PayPal billing, third-party integrations — shipped ready for prod, not a notebook.

S · 03

Web scraping at scale

Playwright and Selenium scrapers parsing millions of points per day. Anti-bot handling, retries, proxy rotation, warehouse-ready output.

S · 04

Ops automation & bots

Telegram, Slack, Discord, n8n, cron. Turning a chain of 6 human clicks into one scheduled job that runs silently forever.
