Schedule Interview NowMy name is Vadym B. and I have over 9 years of experience in the tech industry. I specialize in the following technologies: JavaScript, Elasticsearch, GraphQL, node.js, LoopBack, etc.. I hold a degree in Bachelor of Science (BS), Master of Science (MS), Master of Engineering (MEng). Some of the notable projects I’ve worked on include: REST API for mobile application, NodeMoney. I am based in Kyiv, Ukraine. I've successfully completed 2 projects while developing at Softaims.
My expertise lies in deeply understanding and optimizing solution performance. I have a proven ability to profile systems, analyze data access methods, and implement caching strategies that dramatically reduce latency and improve responsiveness under load. I turn slow systems into high-speed performers.
I focus on writing highly efficient, clean, and well-documented code that minimizes resource consumption without sacrificing functionality. This dedication to efficiency is how I contribute measurable value to Softaims’ clients by reducing infrastructure costs and improving user satisfaction.
I approach every project with a critical eye for potential bottlenecks, proactively designing systems that are efficient from the ground up. I am committed to delivering software that sets the standard for speed and reliability.

DataArt
This is a mobile networking app, that helps you to find your potential partners, using AI. - I developed back-end on node.js using such frameworks: connect, express, sequelizejs, swagger. - DB: the main db is postgres; for fulltext search used elasticsearch (Lucene), for AI mssql - I also built front-end using Angular2 - For mobile notification was used Firebase Cloud Messaging (FMC) - For deeplink I used Branch.io - Mailgun was used for sending emails
Cryptocurrency built from scratch in node.js using Proof of Activity algorithm. - fronted was implemented on angularJS; - backend using such modules: "net", "express", "connect" , "nat-upnp", "crypto", "bigint", etc; - for structuring async code used generators; - portmapping in "nat-upnp" was overwritten for exchanging notification between peers in common network; - for saving data continuity, each next transaction include hash from current and prevent transaction forming blockchain; - each transaction signed by sender's private key; - each blockchain also has prevent block identifier and hash from all block;
