ABOUT ME

Results oriented Software Architect and FullStack Developer focusing on efficiency and quality

Make things done!

I'm a professional software architect & full-stack engineer with 18 years of experience and 10 years in freelance/contract work. I have been working for companies ranging from the Fortune 500 list to some small local companies. I also have experience as a startup founder. My core competency lies in the world of scalable web applications and platforms, cloud SaaS and PaaS, the blockchain, desktop software, and games development.

Some of the services which I would love to provide to my customers:

End-to-end product creation for innovative startups. I will help to understand the requirements, design the architecture which solves the current needs and is ready to expand when the product will start to grow, split the job into individual chunks and either execute these myself or oversee others doing the coding, ensuring that all of the business goals (including keeping development costs under control) are met.
Rapid and cost-effective MVP/product prototype, so the client in the meantime could work on raising the investment or getting initial market feedback for the idea.
Performance, scalability and stability improvements for existing products with a complex codebase.
Code reviews and refactoring to ensure that "technical debt" is under control and doesn't restrain future growth.

I'm multi-stack and multi-role and able to give valuable and justified suggestions on a stack of technologies to use or approach to achieve the desired result.

I'm easy-going, friendly, and fun - but at the same time focused, responsible and accurate. I will always share the "concern" with you if something is not right to ensure that everyone is fully aware of the situation.

I'm ready to take responsibility and be your "right hand" in getting the job done.

Multiple web apps created with the python stack, with the most complex ones being: • Highly scalable web application providing websites for dealers with inventory management, configuration, and multiple other options • Reservation system with a powerful backend and sleek frontend to allow customers to reserve a table in a high-end dining restaurants • ERP-on-the-cloud solution • Online collaboration tool which is a mix of upwork, github, google cloud, google docs and blockchain in one service. I write a self-validating code which follows the Zen of Python.

• Founded and developed a product for collaborative development with the help of the blockchain - https://dogezer.io • Created and started a company with a team of other freelancers (started with three, grew to 11 people) who I've been managing throughout the time of active development (2017-2018). • Created a still running SaaS collaboration platform that has an option to create your own project crypto token, organize an ICO and a bounty program. • Implemented my own framework combining the functionality of tools like GitLab, Slack, and Google Docs into one. Combined: Teams and projects marketplaces, cloud storage, integrated file manager, cloud documents editor and messaging, issue tracker, a payment system in fiat and on the blockchain, automated deployment of blockchain smart contracts and ICOs. • Designed a very detailed whitepaper for a blockchain project aiming to explain the project to future users and investors. • Attracted over USD $1 million in ETH and BTC investments by running an ICO of DGZ token. • Finished a massive marketing campaign for the ICO and the project, which included participation around the world in blockchain enthusiast conferences, internet marketing, and community management. • Organized a bounty campaign, which involved users in sharing referral links, which provided an investment bonus when buying DGZ tokens in the ICO. • Designed special smart contracts using Solidity in Ethereum Virtual Machine, which were to make mandatory automatic payments in fiat to team members who collaborated to the project created, executed, and finished on the platform.

At Trilogy I've developed many projects: 0. I've developed a micro-website that collects bigdata from a massive number of users who visit dealers' websites of Ford, Hyundai, Dodge, Cadillac. The back end was gathering data about user interactions on the platform, much like Google Analytics. 1. Created a highly-scalable management system "Autoplatform" for the data collected from dealer's websites. The service allowed to generate vehicle descriptions with a highly-customizable set of options and export the selected data through a REST API. 2. Developed the second project called "NextGenDealerSite(NGDS)", which utilizes the REST APIs of the "Autoplatform" to build a set of available vehicles for the selected local dealer to display on a website that is also built using this tool. The developed system was supported by over 1000 dealers of Ford, Hyundai, Toyota, Jaguar, and Land Rover for their websites, all on different domains for each dealer. 3. The third project was adding a "Build and pay" layer on top of the NGDS. As the name suggests, users of the websites could preorder a customized vehicle to be delivered to the dealer and then purchased by the customer.

A complex ASP.NET-based web tool with heavy use of JavaScript for OZON-NN, requested due to their expansion. The tool was essentially a CRM and inventory management solution. Developed solely by myself after getting a very high-level task explanation from OZON-NN, analyzing business needs, and creating technical requirements. VB.NET has been used as the main development language. The developed solution proved to be reliable because it is still used in the company.
