About Krunal
Senior backend engineer with 18 years on distributed and event-driven systems, high-scale platforms, and regulated environments.
Continuously responsible for a Dutch Ministry of Defense (MoD) platform deployment since 2022 — first as engineer at Qualibrate, maintained through the Copado acquisition, and ongoing today as freelance partner.
3+ years of unbroken engagement with one of the most demanding regulated
environments in NL.
Other highlights:
- Smartlink IoT (Pitney Bowes) — 60M+ events/day at sub-2s latency, presented at AWS re:Invent.
- Qualibrate (B2B SaaS) — built platform from 0 to acquisition by Copado.
- PriceSpider — Post-acquisition of two more companies, I build greenfield systems, unified stack, re-architected legacy to deliver low-latency APIs at 2500 TPS for global retail.
Strong on Go, Java, AWS, Kubernetes, Terraform, Kafka, event-driven architecture, and high-availability systems where compliance and audit trails are non-negotiable.
Currently freelance via my company Zeoxia (NL BV). Available for senior IC engineering, architecture, and platform work — remote-first, EU timezone, English.
Best fit for projects where reliability matters more than novelty.
