1 ONE TEAM, FOUR LOCATIONS, THREE TIME ZONES. ONE GOAL. TEAMS OVERVIEW Sqor Sports - San Francisco, United States Inaka - Buenos Aires, Argentina Erlang Solutions - Stockholm, Sweden Erlang Solutions - Budapest, Hungary Pacific Time Zone UTC-08:00 Argentina Time Zone UTC-03:00 Central European Time Zone UTC+01:00 Central European Time Zone UTC+01:00 Sqor Sports San Francisco based tech startup. Sqor Sports is a sports social network, focused on providing the latest news, scores, and exclusive access to teams and athletes. Sqor Sports work with current and former athletes across all major sports, making direct connections with fans to boost brand awareness, promote new project launches, and drive sales growth. 75% of Sqor s users are mobile, so the importance of having highly reliable ios and Android apps is crucial enabling all users to access Sqor anywhere at any time. INAKA Buenos Aires startup, acquired by Erlang Solutions (ESL) in Experts in bootstrapping; taking a startup idea and build it to minimum viable product, before the client team takes over. They help clients launch quickly, with a codebase that can grow with them and their business. Inaka have extensive experience in designing end-to-end web and mobile apps in Java, Objective-C, Ruby, and use other leading technologies i.e. Android, ios, Rails, Riak, Elasticsearch, Redis, MySQL, and Heroku. Erlang Solutions Founded in 1999 soon after Erlang was released as open source. We specialise in providing businesses with truly scalable solutions through the creation, integration, delivery and lifetime support of a wide range of products and services. We have an extensive experience in system architecture and design, migration to OTP, prototyping, coding, integration, testing, profiling, code rewrites, code and architecture reviews and maintenance. Our HQ are in London with teams working from offices across the globe: Stockholm, Krakow, Budapest, Berlin, San Francisco and Buenos Aires.

2 PROJECT SUMMARY Erlang Solutions and Inaka fortified Sqor Sports legacy apps/servers by implementing several code improvements and refactors. For Sqor Sports to grow as they have projected, we planned and migrated their currentlegacy apps/servers to scalable and more reliable solutions. We also established important practices such as speccing/estimating proposed features, documentation, pull requests, test coverage and implemented new features. + + For ios (Mobile) that means transitioning from C# to Swift. + + For the Frontend that means moving from Backbone to Angular. + + For the Backend that will entail a complete overall architecture in Erlang. One of the project s highlights up to this point is the unique chat feature we developed in the mobile app from scratch. The chat, with its custom features, will be instrumental in differentiating Sqor Sports from its competitors. An iteration of this chat will be released to the app store in next month. TIMESCALE: start June 2015, complition scheduled for end of 2016 (mainly for the frontend and mobile); it is a long-term project. TEAMS BREAKDOWN Our remotely deployed team was built of 24 experts from many disciplines and offices. For this project to be delivered successfuly, it was important to have a leader within each team and on the top an overall Project Manager (in this case it was a PM from Sqor Sports). We also embedded developers within client s office and vice versa. Sqor Sports has sent 1 Junior Android and 1 Junior ios Developer to Inaka s Buenos Aires office, so that they could learn from our Senior Developers assigned to this project. 24 EXPERTS 4 LOCATIONS 3 TIME ZONES 1 GOAL Sqor Sports team 11 team members based in Sqor s San Francisco office main Project Manager ProJECT Leads ios Developer Android Developers Frontend Developer Erlang Backend Developers ESL & INAKA team 13 team members based in various locations Project Manager BA ios Developers BA Android Developers BA Angular Frontend Devs BA & BZ Erlang Backend Developers HU XMPP Backend Devs SE

3 COMMUNICATION, TOOLS & COMMON FRAMEWORK In a remotely deployed team working on one common goal, it is crucial for all team members to use one common framework, use a coherent communication system and be diligent in using the same tools. Two major aspects in managing remote collective teams are: + + Communication (two flows: ESL + Inaka + Sqor Sports for all stakeholders; and another flow for ESL + Inaka). + + Tools (task management tool Jira (Pivotal); internal messaging tool Slack - we created internal chat rooms for each team (Backend, Frontend, Mobile etc); daily standups on Google Hangouts and Skype). COMMUNICATION BETWEEN ERLANG SOLUTIONS + INAKA + SQOR SPORTS: + + Daily standups with all teams: Backend, Frontend, Mobile with our Project Manager attending all calls. All team members are encouraged to share what they are working on; it is also a great platform to mention any blockers, issues and ask questions. + + Weekly calls between ESL/Inaka Project Manager and Sqor Sports VP of Engineering. + + Weekly calls between ESL/Inaka and Sqor Sports Backend Developers (planning stage 2 and discussing specific tasks and features development). + + Adhoc calls - when facing an issue or sharing an idea. + + Face to Face workshops. Before commencing any work on stage two, we organised an intensive one week face to face workshop in San Francisco. For one distributed virtual team it was a great opportunity to discuss version 2 architecture, meet each other and establish frameworks and the roadmap. Attendees: 1 Lead, 1 Senior Developer from Erlang Solutions (Budapest), Sqor Sports CTO, Project Manager and all Backend Developers. COMMUNICATION BETWEEN ERLANG SOLUTIONS + INAKA: + + Daily standups with ESL and Inaka Developers and a Project Manager to discuss the workload, progress and any issues before reporting to Sqor Sports. + + Regular face to face meetings between Mobile, Frontend teams and a Project Manager (Buenos Aires office). + + Adhoc calls - when facing an issue or sharing an idea.
