Hi, my name is
Harmohan Singh Johal.
I build cloud infrastructure at scale.
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 — from managing cloud servers and firewalls to implementing monitoring with Prometheus, Grafana, and New Relic. I automated backup and disaster recovery workflows that achieved zero data-loss incidents during my tenure.
I hold an MSc with Distinction from Nottingham Trent University, where 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.”

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 sub-5% RMSE 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.
GitLab CI/CD Pipeline Architecture
Designed and implemented multi-stage GitLab CI/CD pipelines for WordPress (PHP), Java, and containerised applications — including automated tests, Docker builds, and deployment stages used in production.
- ▹Defined reusable YAML pipeline templates supporting build, test, and Docker image push stages.
- ▹Integrated Bash pre/post-deploy health-check and rollback scripts.
- ▹Reduced deployment time by ~40% and eliminated all manual deployment steps across client projects.
Automated Backup & DR System
Bash and Python automation system for scheduled database backups, S3 upload, retention management, and restore testing — achieving zero data-loss over a two-year production tenure.
- ▹Scripted MySQL dump, compression, and aws s3 cp upload with S3 lifecycle policies for cost-efficient retention.
- ▹Implemented automated restore testing via Cron to validate backup integrity on a monthly schedule.
- ▹Sent email alerts on backup failures, ensuring rapid incident response.
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.
- ▹Deployed Prometheus with custom node_exporter scrapers and application-level metrics.
- ▹Built Grafana dashboards covering server health, application latency, and database query performance.
- ▹Configured New Relic APM agents on Java and PHP services for distributed tracing and error tracking.
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.
- ▹Deployed Snipe-IT on Linux with MySQL and Nginx, configured with SSL and LDAP authentication.
- ▹Migrated legacy spreadsheet inventory into the system, improving overall asset visibility.
- ▹Generated procurement and audit reports for senior management, streamlining hardware decisions.
