01 Experience

Senior AI Automation Engineer SEP 2024 → PRESENT

SOKIL
• Architected a dual-server AI automation platform (prod + dev, 16 vCPU / 160 GB) with formal workflow definitions, isolated credentials,
Dockerized services, TLS, backups, and observability, enabling 29+ production workflows to run continuously on a self-hosted stack.
• Designed and orchestrated multi-agent support and document workflows across Telegram, WhatsApp, CRM, Sheets, and internal SaaS
channels, combining RAG, tool-calling, state-machine dialog control, and approval routing to reduce Tier-1 support load and manual
document handling.
• Established quality and validation practices for AI systems through OpenAI regression eval suites, Playwright security testing, and
controlled prompt/config management, giving leadership repeatable visibility into model behavior and release safety.
• Specified and shipped a multi-tenant HR CRM SaaS on Next.js 16, React 19, and self-hosted Supabase with DB-driven prompts, RLS
hardening, encrypted API keys, audit logs, signed storage, and per-workspace controls, passing internal security review after fixing
HMAC, SSRF, injection, and cross-tenant leak risks.
• Engineered an agentic job-market intelligence pipeline across 17 sources using REST, RSS, Playwright, and FlareSolverr, with two-stage AI
scoring, deduplication, daily delivery, and CRM webhooks, alongside a parallel content automation system with persona-based
generation and approval queues.
