## What I'm looking for

```text
I'm looking to build and ship high-impact AI and SaaS products end to end, combining product ownership, agent systems, full-stack engineering, automation, and production delivery.
```

## About

```text
I've built MatchupWise, an AI career platform live in 25 languages with more than 10 tools, including ATS scanning, job matching, interview simulation, career planning, and application tracking. I developed its agent runtime, domain agents, evaluation harness, multi-provider LLM orchestration, and automated multimodal content pipeline from scratch.

I'm also building Dijimasa, a multi-tenant hospitality SaaS for restaurants, cafés, and hotels. It combines POS, reservations, QR ordering, payments, delivery integrations, hotel booking, in-room service, financial reporting, and AI features in a production platform.

As the sole engineer behind both products, I own FastAPI, PostgreSQL, Redis, WebSockets, Next.js, TypeScript, AWS, Docker, GitHub Actions, and production delivery end to end.

My work also includes self-hosted open-source multimodal models, structured-output validation, LLM evaluation, multilingual automation, programmatic SEO, and automated publishing for YouTube, TikTok, Instagram, and Facebook. I previously led projects, marketing, purchasing, technical sales, budgets, teams, and stakeholder delivery across multiple industries.
