  • Hands-on familiarity with optical protection schemes including 1+1 OLPS (Optical Line Protection Switch), ASON/GMPLS mesh restoration, and dark fibre/spectrum path design
  • Proven track record designing high-capacity, sub-millisecond low-latency DCI topologies linking major Singapore carrier-neutral and hyperscale data centers (e.g., Equinix, Global Switch, Digital Realty, Singtel DC).
  • In-depth knowledge of Layer 1/Layer 2 wire-speed optical encryption protocols (MACsec, Quantum-Safe / QKD integration) for ultra-secure data transport.
  • Hands-on knowledge of high-density 100G/400G client handoffs, transponder/muxponder architectures, and DCI-specific overlay/underlay integration (e.g., EVPN-VXLAN over DWDM/OTN).
  • Strong foundation in BGP-4, OSPF, MPLS (L2VPN / L3VPN / VPLS), Segment Routing (SR-MPLS / SRv6), and Metro-Ethernet (MEF 3.0 CE standards)

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
