The problems, the tools and the results.

Explore how I reduced network energy use, automated incident assignment and brought fragmented information into one workspace. Then inspect the public code or the story of a team-led MVP.

Energy usereduced through RAN automation

I reduced energy use in Vodafone Spain’s RAN.

While supporting Vodafone Spain’s RAN from the Atlantic NOC, I designed, developed and implemented the Python and ISSTAR automation. I also coordinated the team resources and planned and executed the production change requests (CRQs) needed for rollout.

Problem

The opportunity was to reduce RAN energy use without disrupting live network operations.

Constraints

The rollout required controlled production changes, operational checks and coordination of the people available to deliver them.

My responsibility

I led the work from concept to rollout: I designed, developed and implemented the automation, coordinated team resources and planned and executed the required CRQs.

Approach

I used Python and ISSTAR to automate the energy-saving workflow, then introduced it through controlled production changes.

Impact

The automation reduced network energy consumption and operating costs. I delivered it through planned production changes and coordinated rollout activities.

What this shows

The result depended on both the automation and the operational planning needed to deploy it safely.

Assignmentautomated around team availability

Automated BMC Remedy ticket assignment for my team.

I built a Python workflow that read our daily Excel roster, assigned tickets to available team members, sent email alerts for higher-priority tickets and recorded ticket metrics.

Read case studyClose case study

Problem

Ticket assignment was manual and had to account for who was available each day and which tickets had the highest priority.

Constraints

The workflow had to use the team’s existing Excel roster and BMC Remedy process, while alerting higher-priority work and retaining useful metrics.

My responsibility

I designed and built the workflow for my team around its existing roster and ticket process.

Approach

The Python workflow read the daily Excel roster, assigned BMC Remedy tickets to available people, sent priority alerts by email and recorded ticket metrics.

Impact

The team gained an automated assignment workflow integrated with its existing plan, with priority alerts, assignment history and operational reporting.

What this shows

Designing it around the team’s existing roster and workflow made it practical to use.

RAN portalseveral data sources in one planning view

One workspace for fragmented RAN information.

I conceived, developed, deployed and maintained Phoenix, a PHP, Python and MySQL portal bringing multi-vendor RAN information, checks and reporting into one operational workspace.

Read case studyClose case study

Problem

The RAN information used to prepare network projects was spread across several operational data sources.

Constraints

The portal had to integrate existing operational data sources and a proprietary environment. A sanitised source archive is public; production data, configuration and internal endpoints remain private.

My responsibility

I built the portal for the team I worked in, based on the information we needed to prepare network projects.

Approach

I used PHP, Python and MySQL to combine RAN information, searches, consistency checks and reporting in one web application.

Impact

The team could consult the RAN information needed for project planning in one place.

What this shows

The portal was useful because it presented the data in the same context in which the team planned network projects.

Selected authorised source archives are linked below. Production data, credentials and internal configuration remain private.

Selected professional archives

Systems I built for real operational work.

These repositories preserve authorised, sanitised code from retired workflows. They show how I translated operational problems into tools used by the teams where I worked.

ApolloMed Tech: leading and building a health-data wallet MVP.

A six-person project that grew from a degree assignment into a working web and mobile MVP, competition pitches and a business plan. I led the team and contributed directly to the Go web application, microservices and Fabric integration.
