Tigran A.

Hello, I am a web-development professional with 10+ years of experience building and improving small to big live projects, mostly Ruby on Rails, but have hands on experience with live Elixir and Phoenix projects. My core competency lies in the ability to jump into an existing project, read its code, and start delivering fixes, improvements, and features without delay. As a professional, I want to be a reliable developer who will help you build a good product. I will hear what you need, evaluate it from different perspectives based on my knowledge, then I will give you feedback, we will clarify the task, and I will deliver what we agreed on. I do remember to keep a good balance between development speed, app performance, and maintainability. Which means sane code cleaning, optimization, or testing. Personally I am striving to be reasonable, responsible, and independent, with good emotional health and control. I am interested in a long-term collaboration, preferably part-time(to maintain good work-life balance), comfortable both solo and in a team. Some of my interests: walking, pong, badminton, trekking, mindful sci-fi, chess, engineering, physics, biology, and mind.
