Portrait of Deepak Dinesh, Senior IT Systems Engineer

Architecting the Edge.

I'm a Senior Systems Engineer in Oman. Ten-plus years of replacing hardware VPNs with Zero Trust meshes, crashing spreadsheets with pipelines, and maintenance folklore with automation that outlives me.

Senior IT Systems Engineer at Maryana Group (2020–present). Right now that's the Zero Trust phase-2 rollout moving the last Tally Prime ERP hop onto ZTNA, after the weekend Tailscale→Twingate cutover that restored ERP access with zero business days lost. I also run OpenClaw as the operational layer over deployments, price pipelines, and memory-backed automation.

Things I Broke (and Fixed)

// Incident discipline: blast radius → root cause → guardrail added.

41-minute blank-page outage, self-inflicted CSP nonce

Placeholder nonce shipped for two months → per-request nonces + 5-script pipeline. Detection now under 4 min.

Redirects that vanished on prebuilt deploys

vercel.json ignored by prebuilt output → 308s rebuilt as routes. No more silent redirect loss.

Deleted the Vercel KV instance on purpose

Rate limiting without a data store: 5,000 in-memory buckets, 1.8 MB idle. Zero-cost guardrail.

Agents rebuilding the portfolio: the DAR loop

Draft → Act → Review with a LIKE/REJECT gate. Automation that asks before it ships.

Trajectory & Proof

2016 → 2020 → present: one company, one promotion arc — IT System Engineer keeping POS alive at 99.9% (see the unified-infrastructure case: ~100% central ERP uptime under AD RBAC), then Senior leading digital transformation across 10+ branches.

Certifications: vendor and platform training pursued on the job — applied credentials over paper ones: win-acme/Let's Encrypt pipeline (RDS cert automation), Cloudflare Workers edge (static-first delivery), Prophet forecasting (7,800-SKU pipeline).

Writing: 22 technical deep-dives in ~/blog — migrations, forecasting, and outage postmortems with transcripts and numbers.

Social proof: Senior IT Systems Engineer at Maryana Group (2020–present); production systems at tweakdeals.com (2,084 live products) and mushtariyat.com (5,000+ monthly visitors).
