Alex is now available for hire Hire Alex

Senior full-stack developer with over 13 years of experience, but mostly expert in Node.js back end. I like optimisation win every way, like code efficiency and resources consumption. Reliability and security is also in my priority. I'm not afraid of any challenging involvements because every complex task had found it's solution during my whole career. Strong mathematics and algorithms knowledge helps me a lot in terms of optimisation too, but still afraid to divide by zero :) In real life I like hiking, billiards, playing guitar and cooking.
