Damian Perera

Software Engineer


Hello, I'm Damian (he/him).

I am a full-stack developer passionate about building scalable, performance-oriented cloud applications and infrastructure.

I believe in failing fast - and my experience in platform design, monolithic migrations, microservices, and enterprise cloud solutions together with a strong passion to learn and keep up with the latest trends helps me in driving ideas from their inception, to design, development, and finally production. Having worked with agile software teams I am both results-oriented and delivery minded.

Engineering Manager, Personio

I had the pleasure to work with Damian for over a year at Personio. During this time Damian has proven to be a very reliable, friendly, team-oriented engineer, always showing a high degree of integrity and ownership. His technical skills not only helped the team but also me to understand the caveats and bottlenecks of our complex monolith-migration project and take proper decision right on time.

It's important to mention that Damian not only shows great technical and social abilities but also has a fantastic product awareness, always being a reliable peer in our cross-functional team. Due to a massive department growth and an urging need for his skills in another team, we're currently not working together but I'm truly looking forward to have the chance to work with Damian again.

Damian is a great addition to any team and I have no doubts I'll hear about uncountable success cases throughout his career as a software engineer.

I really appreciate working with Damian. He is a great colleague with a huge amount of expertise and truly is a team player: He delivers always great quality within his releases as he truly tries to understand the customer's problems as well the product requirements. He supports the onboarding of new colleagues, and with his good mood and openness, he increases the team's happiness. Mostly I am impressed with Damian's architectural and planning abilities. He supported me significantly with a complex roadmap planning of a technical re-architecture of our domain and made sure that all technical aspects and potential risks are considered before and during this complex architectural initiative.

Damian is a rare all-rounder in terms of practical full-stack knowledge, sound architectural foresight and good people management skills. He has demonstrated calm effectiveness in the face of many highly stressful situations.

While Damian was in my team I could rest easy knowing that he would be at the forefront of any issue that would come up, generally with a solution in place before it even gets to me. Aside from his on-point work ethic, he is also a pleasure to work with. Damian is often the life of the party and he demonstrates a passion for drawing the team together and motivating them.

I highly recommend Damian to any team that has a good vision for the future, if he buys into it, he will help get you there!

Damian is one of best Engineers I have worked with in my career.

He is an all-rounder who excels in Full-stack Programming, DevOps, Business alignment, Communication and Leadership at such a young age. Not only does he hold a strong suite of competencies, but also he processes great inter-personal qualities with humility that makes him a great team player and a well-respected colleague among peers. Moreover, I cannot appreciate enough on Damian's pro-activeness, self-engaged passion and extreme accountability when it comes to sustaining our day-to-day operations.

He is indeed a rare gem to find.

Technical Lead, Sysco LABS

Damian is one of the most exceptional characters I have met in my career. He takes pride in every aspect he's doing. He's quite an example for a true full-stack engineer, where he technically excels at every task he's given with. His knowledge on Javascript is top-notch where he has made a lot of contributions to our team as well as the open source community. What I like the most about him, is his curiosity to learn new technologies, evaluate them and quickly adapt into them. He's the kind of engineer who goes above and beyond his assigned responsibilities, to help his project and his team mates whenever needed.

He's also a great team player and a people's person with a solid personality, which indeed makes him adapt to any working environment he's put into. He possesses great leadership skills which will indeed be an inspiration to everyone working around him. He's a young and talented engineer, and he would definitely be an invaluable asset to any team.

Damian worked with me in 2019 during my time as engineering lead for Sysco LABS' customer experience organization. He was one of the more exceptional software engineers in that team: technically solid, hardworking and possessing soft skills necessary for future leadership. One of the things he did was taking ownership of a relatively complicated architectural change that helped improve the application's front-end performance significantly.

He'll be a great addition to any team.

Damian was the youngest in my team and a fine gentleman. He had the challenge to replace the skill set of a senior engineer. Undoubtedly he accomplished that challenge. That was his very first time working in front-end technology. Within a short period, he groomed himself as a well-experienced engineer. He posses strong skills in JavaScript, NodeJS, ReactJS and AWS. Also, he is skilled in Java.

He is a strong communicator. He delivers concepts clearly to different levels of audiences. He blends well with teammates, which makes him a required person all the time. His well-organized work structure helps stakeholders to get a clear picture of how things getting done. He is a go-getter. His friendly behaviour is a great asset to the team.

I highly recommend this wonderful young gentleman without a second thought.

It's not often that you come across individuals with the right balance of skill, passion, and attitude as exhibited by Damian.

I closely worked with Damian on the retail innovation project where he was entrusted with complex tasks that came with frequent changes and tight deadlines. I was particularly impressed by Damian's can-do attitude, teamwork, his passion for new technology and innovation, his ability to adapt to change, and his dedication that led to consistent timely delivery.

Damian would be an asset to any team and comes with my recommendation.
