Sharjeel Abbas

I'm a senior backend and AI infrastructure engineer with 4+ years of experience building startup products for Australian and international teams. I work across TypeScript, Python, Rust, React, distributed systems, and cloud infrastructure.

At Stiki, I lead four engineers and remain hands-on with architecture, production code, releases, and operations. I designed capability-based sharing for a privacy-first social network, built local encrypted discovery flows, and created a NestJS and BullMQ pipeline for content extraction, LLM summaries, embeddings, retrieval, retries, and failure recovery.

Previously, I built a multi-tenant event platform at Upcastr across TypeScript, PostgreSQL, Auth0, and AWS. The work included Stripe Connect ticketing, AI-assisted event creation, queue-based background jobs, testing, monitoring, and CI/CD. At Educative, I improved Core Web Vitals, led a real-time discussion product used by thousands of learners and instructors, and handled production incidents.

I like senior roles where I can make architecture decisions, write the difficult parts, and help a small team ship reliable software. My independent work includes a multi-LLM peer-review platform and a Rust memory engine for local retrieval, graph search, and temporal reasoning.
