What I'm looking for

I'm looking to build high-impact AI-enabled, data-intensive web platforms with international teams, contributing to backend architecture, distributed systems, analytics, and production SaaS products.

At Byteshake, I lead backend architecture and AI systems for Tenderbase, a procurement intelligence platform aggregating more than 500,000 global tenders.

I build distributed Python scraping engines, LLM-powered parsing, vector-based semantic search, and ClickHouse analytics pipelines that support fast discovery and multi-million-row reporting.

Previously at CureTech, I engineered Tajabajar’s grocery e-commerce platform, internal ERP and CRM systems, mobile delivery APIs, and competitor-price intelligence pipelines. I also built responsive React and Next.js experiences connected to Laravel backends.

I bring over six years of full-stack engineering across Laravel, Python, React, Vue, AWS, and production SaaS platforms, with experience collaborating asynchronously across international teams.
