Nikolay Grishchenko

Cloud architect and engineering manager — I build highly-available, high-load applications on AWS, and I love sharing the craft.

I love Python and I love AWS, and I build highly-available, high-load systems out of serverless, event-driven components — somewhere between 500 and 1,000 Lambdas across the companies I’ve worked with (300+ at Better Impression alone). I’m an AWS Certified Solutions Architect Associate, and with colleagues and open-source enthusiasts I maintain sosw, a framework for orchestrating AWS Lambda.

Most of all, I love to teach — which is why SOSW runs training programs for developers, alongside consulting and architecture design for complex web, event-processing, and data-processing systems.
