What is a successful user onboarding flow and how to achieve it?

Onboarding new users

Microservices architecture with 50+ services.
• Decomposed business features. Working with MVP and full supporting to production aria.
• Managed project/stream architecture.
• Worked with user recommendation services and UGC.
• Shared DevSecOps practice, added load testing for major releases, code review (cross-review).
• Supporting and mentoring AQA team. Helped with e2e and common ci/cd pipeline.
• Tech talks.

• worked around UGC and moderation systems.
• reduced response time SDUI project by 2 times. Zero error rate.
• supported and helped to integrate AQA with common CI/CD pipeline.
• added open telemetry and applications errors metric.
• test coverage control (up from 20% to 60%+)

High load data system. Microservices infrastructure with Java 9+, Kotlin, spring boot and micronaut.
• Moved old services to micronaut and reactive stack. Increased speed of processing by 40%.
• Normalise data-pipelines (ETL) and added concurrency.
• Code review, added tests coverage (up to 60%) and set CI/CD with sonar.
• Added metrics, open telemetry, moved part of audit system to ClickHouse.

Fintech project, NDA.
• Set OAS3 with mock-service. Speeded up development up 3 times with Spec-first principal.
• Shared and set DevSecOps practice to the project. Added opentelemetry.
• Took part of architecture meetings. Successfully moved from monolith to microserices.

Public experience:
• presented at an open microphone event in Java Community, discussing reactive programming approaches and Project Reactor, awarded a certificate for active participation.
• organized meetups for the team on Kotlin DSL tools, changed the project's architecture, and established a minimum standard of 65% for all services.
• Arranged an event at the Java and Kotlin Developers Union on load testing tools, with over 180 online participants.
• Invited as an author to create a practical course on "Multithreading in Java".
• Conducted webinars on various topics with approximately 30 offline and 50 online participants.
• Experience in conducting various sections of technical interviews.

Digital solutions cover more than 1.1 million kilometers of roads and serve more than 11 million users. 

• more than 20 such libraries were created, and to implement the new service it was only necessary to connect the necessary modules.
• added loadtests, opentelemetry, OAS3, increased test coverage to 60%. 
• moved from Spring to Ktor. It speeded up the platform by 35-40%.
• worked through and decomposed into tasks the business logic for services responsible for paying for travel and recording data, integrating them asynchronously into many external systems.
• development transactions data pipelines (etl,elt).

Same time:
• leading backend platform for mobile application as a tech leader. The project implementation from scratch and management, speeding up the data collection process by more than 12 times.
• worked with integrations and payments platforms, ELT, data pipelines.
• optimized data processing - from 1.3 seconds to 0.680 milliseconds, and reduced resource consumption from 2 gigabytes to 512 megabytes by switching to a lighter technology stack.

As a Lead:
• moved from Redmine and SVN to Jira and git.
• added CI/CD and Jenkins - speeding up the production and delivery of releases by 80% - from one hour to less than 10 minutes.
• added load tests before major releases.
Tech:
• moved to microservices architecture with Spring cloud. Added OAuth flow.
• create new services for Integration with 15+ providers of goods, refresh data and create orders. Team could Increase in the number of dealers by 21% and an increase in the range of goods.
• added specifications for all of services. It could help to increase an amount of integration.

• Identified the bottleneck and developed a unique module that reduced the load by 95%.
• Worked with API service and reports (Generate all of available types reports for managers and customers).

• Help desk and supporting B2B systems.
• Most of the tasks concerned orders and delivery.
