Sixteen years turning systems everyone's afraid to touch into ones nobody worries about.

Enterprise architect, 16 years in financial services and healthcare technology. I find the bottleneck nobody's measured yet, rebuild the path around it, and leave behind something the next engineer can actually understand.

Here for: Hiring → Fractional / advisory → Booking a speaker → Mentorship →
The pipeline that was bottlenecked by design most teams would have asked for more servers
18 hrs a single API capped every batch at 10–15 transactions a second

6 min rebuilt on Kafka Connect, the API bypassed entirely

Systems thinking under constraint

I look for the architectural ceiling first — the limit nobody's named yet — before reaching for more infrastructure.

Reverse-engineering the undocumented

Rebuilt a DRM system and rescued a stalled post-merger migration — both with zero working documentation, mapped from what the system actually did.

Multi-cloud, applied not collected

11 certifications across AWS, GCP, and Azure — each one tied to a system I actually built or migrated, not a study sprint.

Risk, translated both directions

16 years moving between regulators, executives, and engineers in financial services and healthcare — fluent enough in each to translate for the others.

"Arun consistently demonstrated a deep understanding of our organization's complex systems and effectively translated business requirements into scalable technical solutions."

Dr. Gaurav Shekhar — Cloud Architect, IEEE Senior Member

"When things got stressful or the timeline got tight, he stayed calm and helped focus the team vs. adding to the noise — an initiative stalled for weeks was resolved cleanly."

Ken Jordan — Ex-CIO/CTO, Board Chair, WSJ Contributor
