I'm a Cloud, DevOps & Infrastructure Engineer based in London, England, specialising in AWS, Azure, GitLab CI/CD, and Linux systems.
About Me
Ever since I was a kid, I was the one who couldn't leave things alone. Remote controlled toys, my first PC, an old laptop that barely worked — I would pick up a screwdriver and open them up just to see what was inside and how everything connected. That curiosity about how things are put together never really left me. It just grew into a career. My first role had me managing physical servers and local infrastructure, which gradually expanded into Linux systems, cloud platforms, deployment pipelines, and everything that keeps modern applications running reliably at scale.
What that progression taught me is that infrastructure work is really about ownership. At Master Software Solutions I was handed real production environments early and expected to keep them running. I was diagnosing live API failures, building CI/CD pipelines from scratch, setting up monitoring so problems surfaced before clients noticed them, and automating anything that didn't need to be done manually twice. That kind of environment shapes how you think about reliability.
The MSc at Nottingham Trent was a deliberate choice, not just a credential. I wanted to go deeper on the theory and system design thinking behind the work I had already been doing in practice. My research project on forecast-driven district heating control won the Best Research Project Award and pushed me to think seriously about how infrastructure decisions ripple upward into the behaviour of everything built on top of them.
“Self-belief and hard work will always earn you success.”

Experience
Cloud, DevOps & Infrastructure Engineer @ Master Software Solutions
Ludhiana, India
I joined as an infrastructure engineer and moved into cloud and DevOps within months, taking on end-to-end ownership of production environments, deployment pipelines, and operational reliability across multiple client projects.
Cloud
- ▹Managed 15+ cloud environments across AWS and Azure, keeping applications available and performant across development, UAT, and production.
- ▹Provisioned cloud infrastructure from scratch including virtual machines, security groups, IAM configuration, networking, and static IP assignment.
- ▹Resolved a live API performance crisis by identifying the root cause through log analysis, coordinating a server upgrade, and introducing automated cache-clearing to prevent recurrence.
- ▹Coordinated environment readiness for releases, aligning infrastructure changes with deployment schedules and client requirements.
DevOps
- ▹Built and maintained GitLab CI/CD pipelines to cut manual deployment effort and improve release consistency across multiple teams and environments.
- ▹Delivered containerised deployments for multi-service application stacks, improving environment consistency and reducing risk during releases and rollbacks.
- ▹Automated database backup and recovery with cloud upload to S3, reducing manual overhead and ensuring data could be reliably restored when needed.
- ▹Set up monitoring across infrastructure and applications using Prometheus, Grafana, and New Relic, enabling faster detection and resolution of issues before they reached production.
Platform Engineering & IT Operations
- ▹Maintained 20+ on-premises Ubuntu servers on VMware ESXi, keeping internal platforms including self-hosted GitLab, Redmine, and Snipe-IT available and reliable.
- ▹Administered Linux servers including patching, upgrades, security hardening, and performance troubleshooting across hosted application environments.
- ▹Supported firewall and VPN configuration using Sophos and SonicWall, maintaining secure network access and reviewing logs for suspicious activity.
- ▹Researched, evaluated, and deployed Snipe-IT as an open source solution, designing the asset structure and introducing ownership tracking to give the business its first clear, auditable view of IT assets.
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.
IT Administrator @ Target Systems
India
- ▹Kept the local network running reliably by troubleshooting routers, switches, and firewalls, resolving connectivity issues before they disrupted operations.
- ▹Managed user accounts, access rights, and operating system setup across the organisation, supporting secure and consistent access to systems.
- ▹Handled backups, data recovery, and end-user technical support, reducing downtime and keeping day-to-day operations running smoothly.
Professional Highlights
GitLab CI/CD Pipeline Architecture
Built multi-stage CI/CD pipelines from scratch for WordPress, Java, and containerised application stacks. Pipelines covered automated builds, Docker image creation, environment promotion, and production deployment — reducing manual release effort and improving consistency across development, UAT, and production.
Automated Backup & Disaster Recovery
Designed and implemented automated database backup workflows using Bash and Python, with scheduled execution via cron, cloud upload to AWS S3, and periodic restore verification on test environments. Eliminated manual backup handling and gave the business reliable, testable data recovery.
Infrastructure Monitoring Stack
Built a centralised observability platform across cloud and on-premises environments using Prometheus, Grafana, and New Relic APM. Configured dashboards and alerting for key services, improving visibility and enabling faster incident detection and response.
Snipe-IT Asset Management Platform
Researched and selected Snipe-IT as an open source asset management solution, then deployed and configured it from scratch. Designed the asset categories and ownership model, populated the system, and introduced tracking processes that improved procurement transparency and reduced equipment loss.
Projects
Forecast-Driven District Heating Control
ML-powered forecasting platform that predicts heat demand from weather data and translates predictions into actionable scheduling decisions, reducing energy waste and improving operational efficiency. Awarded Best Research Project at Nottingham Trent University.
- ▹Trained CatBoost regression models on 3 years of historical heating and weather data, selected over XGBoost and Random Forest based on lower MAE and better handling of categorical features.
- ▹Exposed predictions via a Flask REST API consumed in real time by a Grafana dashboard built for system operators.
- ▹Containerised the full pipeline including training, API, and monitoring stack using Docker, with Prometheus instrumentation for production observability.
Event Booking Web Application
Full-stack event booking platform built to enterprise architecture standards, awarded Exceptional Distinction in Service Oriented and Cloud Technologies at Nottingham Trent University.
- ▹Designed and built a Java REST API using JAX-RS/Jersey with DAO/DTO architecture, fully tested with Postman and JUnit.
- ▹Built a React SPA consuming the API with full CRUD support for events, registrations, and bookings.
- ▹Packaged the full stack with Maven and Docker for consistent, reproducible builds across environments.
