About

Experience

  • Founder and CEO at Hasky Technologies
    Nov 2025 - Present · 8 mos

    Singapore SMEs face an impossible choice: settle for rigid SaaS, pay $50-100K+ for custom development, or hire expensive in-house teams. I started Hasky Technologies to eliminate that trade-off. We use AI-assisted development to build enterprise-grade custom software — CRMs, logistics optimisers, workforce management systems, WhatsApp automation — and deliver production-ready systems in weeks instead of months.

      Turned complex business needs into reliable AI systems at scale and guided cross‑functional teams through the full lifecycle of enterprise deployments: discovery, rapid POCs, hardened production, and continuous improvement across a $20M business.
