01About

Platform Engineer with extensive experience operating distributed systems across cloud-native and air-gapped production environments. I've integrated on-prem and cloud-based fintech platforms, telecom backbones, data pipelines, and hyperscaler infrastructure — with deep expertise in Kubernetes, Linux, and the full observability stack. I'm comfortable owning infrastructure end-to-end, from architectural design through day-2 operations, in lean, high-accountability environments.

02Experience
Senior Infrastructure Engineer · Digitata Networks
May 2025 — Present
DevOps / SRE · Pakistan (Remote)
  • Design, deploy, and operate a multi-node Docker Swarm platform hosting web apps, MinIO S3 buckets, and Airflow workloads for production customer deployments — owning reliability from build through day-2 ops.
  • Build and maintain a full observability stack: Prometheus + cAdvisor for metrics, OpenTelemetry collectors feeding structured logs into ClickHouse, Grafana dashboards, and synthetic health checks alerting into Teams and Slack.
  • Own platform security across customer-facing Linux infrastructure — firewall rulesets, VPN integration, TLS termination, and access controls — iteratively hardening as new attack surfaces emerge.
  • Maintain infrastructure-as-code with Ansible and GitLab CI to automate provisioning, prevent config drift, and ensure reproducible environments; contributed to Kubernetes migration planning off Docker Swarm.
  • Build data pipelines with Apache NiFi and Airflow for telecom datasets, and define infra standards, deployment procedures, and operational runbooks used as the team's reference.
Customer Cloud Engineer · DigitalOcean
Mar 2024 — May 2025
Premium Cohort · Pakistan (Remote)
  • Technical contact for top-revenue customers across Kubernetes, networking, and object storage — consistently meeting a 20-minute SLA and maintaining a 4.5/5 CSAT via Slack and Salesforce.
  • Subject-matter expert across the product surface, contributing to daily scrums and bi-weekly product discussions with engineers and PMs.
  • Led the customer-facing side of a legacy product sunset — coordinating migration guidance and proactive comms that measurably reduced complaint volume.
  • Advised customers migrating from competing clouds: diagnosing config gaps, validating networking and Kubernetes setups, and ensuring post-migration stability. Built a library of playbooks, MOPs, and runbooks adopted team-wide.
Technical Consulting Engineer · Modirum (now Entersekt)
Dec 2022 — Mar 2024
Pakistan (Remote)
  • Resolved issues across all 3-D Secure domains (ACS, 3DSS, MPI, 3DS-SDK, DS) for payment processors, issuers, and payment systems globally — on both on-prem and SaaS distributions.
  • Evaluated, tested, and recommended fixes in line with PSD2 guidelines — including transaction log analysis, SQL querying, and Azure environment monitoring.
  • Integrated a FreeBSD environment into in-house monitoring infrastructure using Prometheus and Grafana.
DevOps Engineer · Ericsson
Apr 2022 — Dec 2022
Islamabad, Pakistan (Hybrid)
  • Operated the Ericsson Wallet Platform — a financial-grade mobile-money system on Kubernetes in a fully air-gapped production environment with zero external dependencies, meeting a 95% uptime SLA.
  • Managed the full observability stack (Prometheus, ELK, Grafana, in-house tooling) offline — ensuring issue detection within 15 minutes via internally mirrored tooling and offline-capable runbooks.
  • Integrated third-party nodes including SIEM solutions and payment gateways; ran UATs and SITs with customers to validate features before production promotion.
  • Performed Linux administration and O&M on Tanzu Kubernetes Grid (later migrated to HPE Ezmeral) with no assumption of external package or image availability.
Systems Engineer II · Ericsson
Jan 2021 — Mar 2022
Islamabad, Pakistan (Hybrid)
  • Monitored nodes and services and configured alerts for timely fault detection across the Ericsson Wallet Platform.
  • Performed Linux administration and L1 back-office support — O&M on VMware vCenter, BOSH, Tanzu Kubernetes Grid, and HPE 3PAR/SSMC.
  • Developed RPA and health-check scripts in Python and Bash, and managed security using F5 BIG-IP LTM/ASM and Tripwire Enterprise FIM.
IP Core & Systems Engineer · Nayatel
Nov 2019 — Dec 2020
Islamabad, Pakistan (On-site)
  • Troubleshot PPPoE/IPoE links and email, domain, and web hosting services; identified and escalated large-scale network issues.
  • Performed CPE router configurations and managed trouble-ticket generation, coordination, and reporting per company SOPs.
