Project is in stealth mode developed by a single person from scratch. It is using within closed communities of target audience. But has 1500+ users already and continue to grow organically. --- Every day, car owners face problems that they need to solve. Every day, they worry about whether everything is fine with their car when they don't see it. Every day, they need to make sure that everything is in order and that all documents are not expired. And sometimes there are problems that also need to be able to solve, and even better to be ready for them in advance. I'm sure drivers can have less of that stress. To do this, I decided to make a service for them, to which they can delegate it. And communicate as with your friend, who can advise them or remind them of something important about their car. It will be able to remind them that they forgot, report when something happened to the car, help solve these problems, and offer services to avoid any nuances. Show less

I was leading small teams (up to 10 people) and full SDLC worflow of different projects from idea to production, and futher product growth, custom & customer integrations. And helped clients with building processes and growing their teams. Was involved as a really full-stack engineer: projects setup, deployments, database schema, backend API, web frontend and mobile apps, release pipelines and so on. But still prefer concentration on backend part. Also was leading teams of engineers with a single stack. Typical tech. stack includes: Python, Django / Flask / aiohttp, Celery, PostgreSQL / MongoDB, Redis, GitHub / GitLab, Heroku / GCP / AWS, React / Next.js and Flutter. Usually that was a development of web/mobile oriented services, microservices, various integrations to existing system, refactoring of existing solutions, etc. Main domains and areas: - Healthcare: platforms for patient and doctor, platforms for providers and while-labeling, integrations (HL7, FHIR 4 & 5, Apple Health, Google Fit, Fitbit); - Accounting & documents: Intuit QuickBooks, Sage Intacct, TaxJar, Adobe eSign, DocuSign; - Data Analytics & Data Science, ETL / ELT; - E-Commerce, CRM, ERP systems and Internal services.

Apr 2020 - Jun 2020
Due to lack of full team and enough resources - project abandoned. --- People should not spend much time on the process of looking for a solution using Google, disturbing their friends or comparing variety of alternatives. The way we want to help them, is to provide ability to ask our service a question, using the same natural language like with friends, but immediately getting short-list with the best solutions. That’s why I created DE-DE - a search engine that can find a solution among online services, businesses and entrepreneurs (on our marketplace). Ordering of results is based on feedback from real people, social value, popularity and user context (preferences, behavior and quiz answers). Show less
