Experience

Software Engineer

Wissen Technology (Macquarie Group)

June 2025 — Present
  • Built a RAG-based knowledge retrieval and LLM inference pipelines so new engineers can understand legacy modules and dependencies in minutes, not hours.
  • Built messaging with 2 platforms (Solace PubSub+) on Java/Spring Boot for a high-volume platform; enabled real-time trade acks and position sync across 3 asset classes (equities, FX, derivatives).
  • Automated bulk trade upload validation in Meteor/JavaScript, calling external REST APIs for settlement dates, restricted stock checks, and market calendars - fewer manual touchpoints and faster processing.
  • Authored 4 doc types—architecture guides, API specs, implementation plans, and runbooks—so dev/support teams could move faster and with fewer escalations.

Marsdrop

Featured onProduct Hunt

Privacy-first, zero-knowledge encrypted file-sharing platform, built and shipped solo end-to-end. Client-side streaming AES-256-GCM encryption keeps the decryption key in the URL fragment so the server only ever stores an opaque blob it cannot read. Files self-destruct on expiry, download-limit, or revoke, with optional Direct P2P transfer over WebRTC signalled by a Cloudflare Durable Object.
