Built and deployed two autonomous AI agents — a QA testing agent running 3x daily (backend API + frontend UI via Playwright, auto-filing Jira bugs with reproduction steps, retesting fixes) and a bug-fix agent that scans Jira, generates code fixes, and delivers GitHub PRs — reducing QA cycle time from hours to minutes.

• Designed multi-model orchestration via OpenRouter, benchmarking LLMs per task: Kimi K2.5 for planning, MiniMax M2.5 for code generation, Gemini 3 Pro for code review, Claude Opus 4.6 for complex bug analysis — optimizing for accuracy and cost.
• Architected secure AI pipelines on GCP with Docker sandbox isolation, VPC network isolation, IAP tunneling, and a 4-stage security gate system with prompt injection detection and immutable rejection logic.
• Engineered progressive Gherkin test coverage expansion (0% → 39% in 48 hours across 59 scenarios), flaky test detection with 3x retry, and a 10-step bug-fix pipeline from discovery through stakeholder notification.
• Integrated 7+ platforms into unified AI workflows: Jira Cloud (JQL, ADF formatting, sprint-aware filing), GitHub (commit monitoring, PR creation, review loops), Slack (Socket Mode real-time alerts), plus domain knowledge of Shariah-compliant financial regulations.

Led 6-person engineering team through SAMA regulatory audit, achieving 100% compliance and securing banking app license in a 4-month timeline.

• Architected Alibaba Cloud migration (Saudi → Global region), reducing latency by 35% and improving availability to 99.95%.
• Migrated 18 CI/CD pipelines from Jenkins → Azure DevOps → GitLab (self-hosted on GKE), cutting deployment time by 45% with zero-downtime rollouts via Helm.
• Implemented observability stack (ELK + Prometheus + Grafana) processing 200K+ logs/day, reducing MTTR from 2.5 hours to 20 minutes.
• Enhanced security posture with GitLab SAST, Docker Scout container scanning — identifying 120+ vulnerabilities pre-production.
• Designed automated QA/Dev KPI system using Zapier + Python, aggregating metrics with Slack reporting.

Designed and owned the CI/CD & infrastructure architecture for Perform Plus, a hybrid‑work productivity platform used by PwC UK consulting teams.

• Migrated legacy Jenkins pipelines to Azure DevOps with gated PR checks and dynamic test‑splitting.
• Provisioned multi‑cloud workloads on GCP & AWS via Terraform with drift detection and cost tags.
• Implemented Gitflow branching strategy and Azure Boards dashboards to visualise delivery KPIs.
• Mentored a team of junior DevOps engineers and introduced runbooks + chaos drills that reduced MTTR by 45 %.
• Acted as DevOps liaison to product owners, analysing risk and advising on cloud adoption roadmap.

• Automated full‑stack environments in seconds with Terraform + Ansible.
• Deployed TOBS observability stack (Prometheus, Loki, Grafana, Promtail) and custom Grafana alerting.
• Built Node.js autoscaler micro‑service using DigitalOcean API to provision droplet pools on demand.
• Implemented security hardening: Bastion host, DB encryption, iptables firewalls and port‑forwarding rules.
• Rolled out OpenFaaS on Kubernetes and set up GitLab CI pipelines for 20+ microservices.
• Authored a Redis ModJS extension to add advanced commands, improving cache ops latency 3×.

Developed multiple micro‑services powering SpaceJat, a collaboration suite:

• Built a Mediasoup SFU for multi‑party WebRTC conferencing (video & audio).
• Created Flokey, an NPM tool to synchronise environment variables across fleets via Redis Pub/Sub.
• Wrote a Playwright scraper that pulls trending videos from Reddit/Pinterest/TikTok and auto‑posts to social media.
• Implemented encrypted chunking micro‑service for large‑file transfer.
• Added geofencing and real‑time notification services (Redis + Firebase).
• Authored end‑to‑end k6 soak/spike/load test suites and CI gates.

• Developed custom Odoo modules (Python/Django/JS) for logistics and finance verticals.
• Containerised Odoo, PostgreSQL and NGINX using Docker Swarm with blue/green upgrades.
• Exposed RESTful APIs documented with OpenAPI, Swagger & Marshmallow.
• Automated .deb packaging and deployment via shell scripts and reprepro.
• Practised Agile Scrum with Jira for sprint tracking.

• Maintained and deployed SAP Point‑of‑Sale by GK across retail clients.
• Built backend features using J2EE, Spring, Hibernate; packaged with Maven.
• Deployed and tested releases on SUSE Linux cloud servers.
• Supported cross‑functional business scenarios (Sales, Finance, Inventory) and reduced defect rate by 30 %.
