## Experience

- Chief Technology Officer, Elite Skills (2025 - Present): Built eliteskills.co from scratch as CTO. AI-first platform where agents coach finance students for elite boutique internships and IB roles: technical prep, MD boardroom simulations, and recruiting tools.
- Co-Founder & Full-Stack Engineer, Sales-Reach (2025 - Present): AI sales-agent SaaS for Shopify merchants (MENA & EU). Branded personas text customers over SMS/WhatsApp after purchase or abandoned cart, run multi-turn sales conversations, and issue personalized discounts as a commission-based growth channel.

- Software Engineer, RevoTech OÜ (2025 - 2026): Full-stack and product engineering across web and game systems (React, Node.js, Unity, Unreal), with an eye toward AI-capable product architecture.
- Lead Game Developer, Independent / Contract (2021 - 2023): Led small teams on game prototypes and systems. Owned technical direction, task breakdown, and delivery timelines.

## Projects

- Sales-Reach: AI sales-agent platform for Shopify merchants (MENA & EU). Branded personas (30+ across Arabic dialects, French, Italian, German, English) text customers over SMS/WhatsApp after purchase or abandoned cart. Multi-turn sales chats, objection handling, personalized discount codes. Commission-based growth channel, not a subscription tool.
- EliteSkills: AI-first career platform built around agents: coaching, career planning, learning paths, resume help, and actionable feedback. Generative AI is the product core, not a feature flag.
- BrainAOS: Self-learning company knowledge graph (Cortex KG) for teams and AI agents. Ingests docs, email, chat, and CRM. Answers with grounded citations. Ships as REST API, MCP server, CLI, and web app with hybrid search, GraphRAG, and connectors for Slack, Gmail, Jira, GitHub, and more.
- EliteSkills Interview: AI Senior MD boardroom agent that stress-tests interview answers in real time. Follow-up pressure modeled on elite boutique superdays, not a static chatbot script.
- SalesBuddy: AI sales coaching where agent clients roleplay conversations, push objections, and give realtime feedback. Feels like a live call, not a quiz.
- Kettl: Marketplace for collecting and trading used cooking oil between restaurants and recyclers. Scheduling, transactions, and verified buyers.
