I’ve always been fascinated by how networks actually work, the invisible systems that keep our world connected. That curiosity grew into a career in network engineering, and today it’s a field that pushes me to learn, adapt, and build better networks.
One moment in particular shaped the way I see networking. I was working during a major outage, and the cause wasn’t faulty equipment but poor visibility and unclear responsibility. Even the best teams amongst us would struggle to respond quickly when there’s a lack of clear-cut visibility, responsibilities and well-done network architecture. That experience made me realise the real challenge in networking isn’t just technical – it’s about clarity, ownership, and collaboration. These lessons shape the work we do at Swer Networks, where I collaborate closely with partners, engineers, and clients to solve complex networking challenges.
Since then, I’ve shared my insights widely. Four of my articles were recognised in APNIC’s ‘Three of the Best’ posts: Edge Router and BNG Optimisation in 2021, IPv6 Architecture and Subnetting Guide in 2023, Out-of-Band Network Design for Service Provider Networks in 2024 and IPTTTH in 2025
My work has also been featured on platforms such as the IPv6 Buzz podcast and The Hedge podcast and was additionally covered by IPv6 Buzz staff in their discussion of my IPv6/NDP article.
I enjoy exploring the creative side of life too, such as photography and music; it keeps me curious outside of engineering and science.
This site is where I share my personal journey, ideas, and insights with anyone who believes networks are more than just background infrastructure.
If you’re as committed to building stronger, future-ready networks as I am, you’ll find this a space to learn, exchange ideas, and push the industry forward together.

October 2023 – March 2024
Network Manager | Mile High Networks (AS395927) & Glacier Broadband (AS395842)
- Same holding company for both.
- Complete network design of AS395842 using service provider architecture to better plan for network mergers and acquisitions as well as multiservice offerings to meet future business goals.
- Principles of IPv6-everywhere, eBGP with OSPF underlay to support different service offerings, BFD for faster network convergence, MPLS, Out of band management for security, DNS, and end to end Jumbo Frames.
- Fully eBGP driven, policy shaped network. There’s no need for route reflectors and/or full-mesh.
- Deployed FQ_Codel which improved Quality of Service and the customer experience by decreasing buffer bloat.
- Fixed layer 2 loops and service provider bridging.
- Network administration and management of a 24×7×365 ISP environment, maintaining SLA.
- Designed a new parallel network that will replace legacy network with minimal downtime.

System & Network Engineer | cldin (AS48635)
A heartfelt shoutout to Wido den Hollander (former MD/CTO of cldin) who gave me the opportunity and served as my technical mentor during my time at the company, from whom I learnt a great deal on best practices for networking from both operational and business standpoint, ranging from network architecture to handling of maintenance, fire fighting and dealing with layer 8 problems.
- Lead engineer for the greenfield design and implementation of a new IPv6 network for AS48635.
- Worked with Data Centre networking technologies such as VXLAN/EVPN.
- Modernised the out-of-band network to increase security and availability of network management.
- Improved network efficiency and performance by implementing best practices and various RFCs.
- Contributed to the development of the company’s network strategy, such as standardising BGP peering policies with third party networks for better WAN traffic engineering.
- Multi-vendor environment including Juniper, Arista, Cumulus Linux, Cisco, MikroTik, and Ubuntu/FRR.
- Handled some network documentation.
- Worked closely with other teams for inter-team disciplinary related works.
- Conducted a technical workshop on MikroTik-specific implementation(s).
January 2021 – August 2023

November 2020 – January 2021
Intern | SkyBroadband Services, Shillong
My contributions were:
- Assisted in deploying RFC4638 which enabled customers to push 1500 MTU over PPPoE thereby eliminating packet fragmentation and improving overall network performance.
- Assisted in identifying security flaw in RADIUS configuration that allowed anyone outside the local network to login the web dashboard of any user’s account.
- Assisted in discovering an MTU negotiation issue with certain make/model of ONT devices that prevented jumbo frames from being transmitted.
