I am a Senior Cloud & DevOps Engineer with 5+ years designing and operating production-grade platforms. I am currently Senior DevOps & SRE Engineer at Netsible Solutions, delivering hybrid AWS/GCP infrastructure, GitHub Actions and Argo CD pipelines, and observability-led reliability for client estates.

My background spans fintech (Amazon EKS, Istio, PCI-DSS–aligned controls), platform automation at Afren.ai, humanitarian AWS advisory with Help.NGO, and independent multi-cloud work with measurable FinOps and compliance outcomes.

How I work with engineering leadership

These are the outcomes hiring managers and platform leads usually care about—whether the role title says DevOps, SRE, platform, or cloud infrastructure.

Platform hardening

Terraform-first infrastructure, least-privilege IAM, network boundaries, and policy checks (e.g. Checkov, Security Hub) wired into pipelines—not afterthought scans.

Delivery velocity

GitHub Actions, Argo CD, and reusable modules so teams ship safely: progressive rollouts, environment parity, and rollback paths that operators trust.

Observable operations

Prometheus, Grafana, CloudWatch, and structured logging so SREs and developers share the same signals—SLOs, alerts, and incident workflows that reduce MTTR.

Core technical skills

Depth across the full delivery loop: design, implement, secure, observe, and operate. Tooling is representative—I adapt to your standards (e.g. Datadog, OpenTelemetry, GitLab CI) where needed.

Where this fits the London market

I do not claim sector tenure at every employer in every city—these are the problem classes I have repeatedly solved on AWS/GCP and Kubernetes, expressed in language that matches local hiring markets.

Fintech & financial services

PCI-DSS–aligned platforms, secure payment and data paths, and resilient multi-AZ or multi-region designs for regulated workloads—matching what London banks, scale-ups, and infrastructure teams typically need.

Healthcare & sensitive data

GDPR-aware patterns, encryption in transit and at rest, and observable ML or data pipelines suitable for providers and healthtech adjacent to NHS-style requirements.

Enterprise & high-growth scale-ups

Terraform modules, GitOps, and cost-aware operations to grow from seed-stage throughput to enterprise controls without replatforming every quarter.

Multi-region & continuity

Disaster recovery, failover thinking, and EU/UK region placement for organisations headquartered in London with global users.

Featured work relevant to London roles

Deeper write-ups and another fifteen+ builds live in the portfolio.

Fintech · Kubernetes

FinBankOps — multi-region EKS

Secure, scalable EKS with Istio, Argo CD, and PCI-oriented controls—automated deployments and strong uptime targets across UK/EU style topologies.

Security · AWS

AWS cloud security assessment

Structured review of production-style AWS: IAM, networking, storage, and application exposure with prioritised remediation for enterprise-style estates.

Healthcare · ML

Patient identity verification (GDPR-aware)

AWS Rekognition and DynamoDB patterns for identity checks with a focus on data protection and audit-friendly design for healthcare contexts.
