Letter of Recommendation
“​I have had the privilege and pleasure of working with Gustav for two years as one of our senior developers. During this time, Gustav's contribution to the team has been integral as he continues to pursue excellence in his work each day, proving to be someone that can be relied on.

Gustav was one of our first hires at the company. The main contributing factor that guided my decision was his dedication to delivering his solution to our internal technical test way sooner than required. He asked clear questions to make sure he knew as much as possible about what was expected. Gustav impressed and stood out by completing more than was required before the due date.

As I've continued to work with Gustav, his dedication to delivering results in a timely manner has been one of his attributes I've come to rely on the most. When a deadline is critical, Gustav will do whatever is needed to deliver within the time frame. He does not allow scope creep or distractions to slow down progress and will preemptively communicate potential roadblocks with stake holders ahead of time.

As a manager, I appreciate his strong communication skills. Gustav takes pride in being able to explain every component of his code, helping all involved in a project to understand, at a development level, the factors contributing toward solid progress, potential risks to the project and improvement possibilities.

Gustav would thrive in a leadership Position, bringing with him a deep respect for those he works with, an unwavering compulsion to deliver quality solutions, and an impeccable work ethic. His dedication to meeting deadlines and business objectives would encourage and motivate his team to constantly strive to be better, and work together as a unit to react to business requirements and changes in an industry which moves and changes rapidly.

It is my pleasure to recommend Gustav Trenwith for any technical or leadership position in a company.​

At Swordfish Software I was part of a team that was responsible for maintaining the legacy system used by call centres around the world to manage debt collection. I was also responsible for reviewing team members work, and planning new enhancements to the system.

On a daily basis I wrote code (PHP, HTML, CSS & JS) to solve bugs and build enhancements for the system. One of my biggest responsibilities was to redevelop the campaign system. This system was used by our clients to manage the debt collection system and included performing tasks such as sending reminder SMS messages to debtors 3 days before a payment is due, making Automated Voice Message calls and performing other actions related to the debt collection process.

Bachelors of Information Technology

Attended the University of Pretoria and completed a 4 year Bachelors of Information Technology, majoring in Computer Science and Multimedia. The degree included honours.

Description from University Info Page: “T​his exciting programme is the first of its kind in South Africa, and integrates, in a four-year programme, the different disciplines related to Information Technology.

Many people have a desire to be professionally prepared for a career in the IT-industry, more than becoming an expert in a particular discipline. The School therefore designed the programme with the explicit aim of ensuring that students have a grounding in all aspects deemed to be a necessary part of the background of the IT-professional. The fourth and final year thus includes a six months' learnership with participating organisations, where students will be employed as trainees.

Due to its nature, the curriculum is tightly prescribed, with relatively few options open to students. This ensures that the group of BIT students have a coherent team spirit, and a shared ideal and vision. The curriculum is also not for the faint hearted, and prerequisites are higher than for most of the other programmes in the School.”​


Attended Hans Moore High where I graduated matric at the top of my class with 5 distinctions in Natural Science, Computer Science, Technical Drawings, Technica Civil and English and an average of 85 % overall.
