Feedback about Lukas Liesis

Over my years in technology I’ve seen thousands of developer resumes. I contact and interview about 10% of them and would hire 10% of the developers I interview. Luka’s immediately stood out as a reliable, highly skilled and talented developer who I can lean on with complex details. Lukas delivers as promised and his thoroughness and thoughtfulness when coding gives me peace of mind to know the job will be done well. I hope to continue working with Lukas for years to come.

Lukas is hands-down the best developer I have worked with in 15+ years of dev hires. He is sharp, intuitive, detail-oriented, and always thinking big picture, several steps ahead. He's not just a developer - he's also part engineer, strategist, and business mentor. What started as a project to fix my app's broken server evolved into a full rebuild — not just to clean up the mess I was in, but to create something that could truly endure and scale for years to come. Lukas tackled complex problems quickly, took my current mess, my verbose notes and ideas, and pages of mockups and has delivered feature after feature in ways I thought would only belong in our "someday" plans, not our current reality. I've watched him map logic, do math, and propose solutions multiple times while live on our calls. Pretty amazing! His communication is just as solid. He kept me in the loop with updates that over-deliver, progress reports, and questions when needed. I always knew exactly where we were in the project and where we were headed next. Lukas's character sets him apart. He's never condescending, never makes you feel like your ideas or opinions are too much. He's professional, patient, and focused on what's best for the project. When he pushes back, I listen because he usually sees something I haven't, and his ideas are gold. If you get the opportunity to work with him, take it. Worth every penny. I look forward to working with him again for our next phase of development.

Lukas is a strong communicator, engineer, problem-solver and get-things-done-er. He delivered on all of his promised and deadlines - almost always over-delivering. I can't recommend Lukas enough. In fact, if you have any doubt as to whether or not to hire Lukas - contact me directly and I'll tell you more.

Lukas was absolutely critical in delivering the front-end part of PRIX first service to customers. I worked directly with him and have nothing but good things to say. Our engineering-team were very impressed with his technical approach and code. But that's not the biggest part of being an amazing engineer. Lukas sees the bigger picture, prioritises, takes initiative, asks for clarification, thinks creatively etc etc. We hope to continue working with him for a long time yet!
