Part of oncall rotation teamProduct focused features:- Split and stitch feature: Splitting larger data annotation job into smaller pieces to enable faster labelling.- Submission and rework feature: Centralised data submission process to customer. Earlier it was a done in a decentralised way. This feature also tracks data submission and rework process and helps identify inefficiencies.Core tech features:- Built incident identification micro service from scratch which helpes us identify inconsistencies in data because of non fault tolerant code. Also helps us identify incidents before customers report them and helps us resolve them, hence improving customer experience.- Large data deserialisation optimisation. I have worked on reducing core microservice memory consumption which helped increase its scalability by 2x- Dropwizard (java lightweight framework) enhancements to make it transactional- Refactoring code for optimisation as well as removing dependency from old micro services which are difficult to maintain- Single Sign On implementation in our system - Aimed at providing enterprise customers easy and controlled access to our SaaS tool.- Media upload - An intuitive drag and drop feature to help clients quick create jobs for annotation and get started with the product.- Subscription management and billing system integration with our Saas productCore tech features:- Working on engineering fault tolerant distributed SaaS system- Worked on Job Cancellation feature which allows end user to stop data labelling

GT-Silicon is a startup which has made an embedded device for pedestrian navigation system in collaboration with KTH Royal Institute of Technology, Sweden. I had worked on their device extensively during the internship to figure out solution to a technical problem present on their device. Magnetometer and pressure sensor present on their device were not functioning properly and I had to figure out an alternate way of programming registers. Work also involved calibrating data from various sensors and sending it to a mobile app.
