JOBUBA (cofounder)

Jobuba is a social, real-time gig platform, where users and companies can offer their gigs (or jobs), and users - jobbers within the distance are then notified of the offer. Jobbers can then bid on the offer with a message, price and availability. Poster of the gig can then select one of the bidders, depending on their price, availability and social feedback received from previous gigs. When the bidder is selected, contact information is revealed to both parties, and they can contact each other via email, phone or in-app messenger.

As a technical cofounder, I was in charge of implementing complete backend, responsive frontend, scalable infrastructure (AWS Beanstalk) and also React Native prototype for Android. I was also acting as a tech lead for our iOS app developer.

Jobuba is built using Angular/RxJs, Python/Django, Elastic Beanstalk, RDS - PostgreSQL, ElastiCache, EC2, Load balancer, Redis. Android mobile app is built using React Native and iOS app is built with Objective-C.

Trackosaurus (ProductHunt hackathon project)

Trackosaurus is trying to address user anonymity when they are interacting with ecommerce web sites.

A lot of users refrain from leaving their email or phone number on a website, if the product they want to buy is out of stock. Why? Well, they risk getting spammed.

We saw the solution in push notifications where users can anonymously sign up for notification when item is back in stock, when seller offers free shipping, when price is dropped, when tickets are on sale, etc...

I implemented backend, FCM push notifications, responsive frontend and installable JavaScript widget.

Trackosaurus was built using Vue.js, Python/Django, PostgreSQL
