Harmohan Singh Johal.
Deploying sleep-well-at-night infrastructure.
I'm a Cloud & Platform Engineer based in London, England, specialising in AWS, Azure, Kubernetes, and GitLab CI/CD. I design and build reliable, automated cloud systems that help engineering teams ship with confidence.
About Me
I am a Cloud & Platform Engineer passionate about building reliable, automated infrastructure. My journey began with hands-on systems administration and evolved into managing production environments across AWS and Azure, designing CI/CD pipelines, and containerising applications for consistent deployments.
At Master Software Solutions, I was trusted early on with critical production systems. My responsibilities ranged from managing cloud servers and firewalls to implementing monitoring with Prometheus, Grafana, and New Relic. I automated backup and disaster recovery workflows that guaranteed data integrity and business continuity.
I hold an MSc with Distinction from Nottingham Trent University. My research project on forecast-driven district heating control received the Best Research Project Award. I combine strong Linux fundamentals with a proactive mindset for identifying inefficiencies and improving processes.
“Self-belief and hard work will always earn you success.”

I began in Platform Engineering and transitioned into Cloud & DevOps within the first few months, becoming responsible for release automation, production support, Linux operations, and observability tooling across multiple client environments.
Cloud
- ▹Supported and maintained workloads across AWS and Azure for development, staging, and production environments.
- ▹Provisioned and managed cloud resources (compute, storage, DNS, access) and handled operational changes with minimal risk to uptime.
- ▹Monitored performance and availability, troubleshooting cloud-side issues affecting application uptime, networking, and resource utilisation.
- ▹Coordinated environment readiness for releases by aligning infrastructure changes with deployment schedules and client requirements.
DevOps
- ▹Built and maintained GitLab CI/CD pipelines (YAML) to automate build, test, and deployment workflows across environments.
- ▹Improved deployment consistency by containerising services using Docker, enabling repeatable builds and smoother rollbacks.
- ▹Implemented and maintained observability using New Relic APM, Prometheus, and Grafana, creating dashboards and alerts for key services.
- ▹Led incident triage and root-cause analysis using logs/metrics, then implemented fixes to prevent recurring issues.
- ▹Automated operational routines (backup checks, housekeeping tasks, reporting) using Bash/Python to reduce manual work and improve consistency.
Platform Engineering & IT Operations
- ▹Administered Linux servers (Ubuntu/CentOS) including patching, upgrades, security hardening, and performance troubleshooting.
- ▹Configured and supported Nginx/Apache for customer-facing applications (reverse proxying, SSL basics, tuning, and uptime support).
- ▹Managed virtual infrastructure on VMware ESXi, supporting VM provisioning, snapshots, resource allocation, and health checks.
- ▹Supported perimeter and access controls using Sophos XG / SonicWall, including firewall policies and VPN/IPsec connectivity.
- ▹Owned backup and disaster recovery routines, implementing retention policies, S3-based storage where applicable, and periodic restore verification.
- ▹Managed IT infrastructure inventory (hardware/accessories), tracked stock levels, and ensured equipment availability for teams.
- ▹Liaised with suppliers and vendors to source, negotiate, and place orders for IT equipment, coordinating delivery and basic setup readiness.
Receptionist | Student Services Centre @ Nottingham Trent University
- ▹Provided front-of-house support at Nottingham Trent University's Student Services Centre, assisting 100+ students and visitors daily.
- ▹Maintained accurate student records and managed appointment scheduling systems, ensuring data integrity and smooth service delivery.
- ▹Successfully balanced part-time employment alongside full-time MSc studies, demonstrating effective time management and professional reliability.
Professional Highlights
GitLab CI/CD Pipeline Architecture
Designed and implemented multi-stage GitLab CI/CD pipelines for WordPress (PHP), Java, and containerised applications. Included automated tests, Docker builds, and deployment stages used in production.
Automated Backup & DR System
Bash and Python automation system for scheduled database backups, S3 upload, retention management, and restore testing. Ensured absolute data retention and reliability during production tenure.
Infrastructure Monitoring Stack
Built a centralised observability platform combining Prometheus, Grafana, and New Relic APM, providing full-stack visibility across Linux servers, applications, and databases.
Snipe-IT Asset Management Deployment
Deployed and administered Snipe-IT open-source ITAM to track 200+ hardware assets, integrating barcode scanning for check-in/check-out workflows and improving procurement transparency.
Projects
Forecast-Driven District Heating Control
ML-driven system using weather forecast data to optimise district heating control, reducing energy waste through predictive scheduling. Selected as MSc research project and awarded Best Research Project at Nottingham Trent University.
- ▹Trained CatBoost regression models on 3 years of historical heating and weather data, achieving high prediction accuracy on unseen test sets.
- ▹Exposed predictions via a Flask REST API consumed by a real-time Grafana dashboard for system operators.
- ▹Containerised the full pipeline (training, API, monitoring) with Docker and Prometheus metrics for production readiness.
Event-Booking Web Application
Full-stack event booking system supporting user registration, event management, and ticket booking. Built as enterprise coursework and awarded Exceptional Distinction in Service Oriented and Cloud Technologies.
- ▹Built RESTful APIs in Java with JAX-RS/Jersey, fully tested via Postman and validated with JUnit test suites.
- ▹Developed a React frontend consuming the API with full CRUD operations for events and bookings.
- ▹Packaged with Maven and Docker for reproducible local and CI environments.
