Andrii Maglovanyi

Front-end Web Developer

Profile

Seasoned Web Developer with a modular and component-driven mindset, adept in bringing forth expertise in design, development, testing, and maintenance of software solutions.

On my way down the road, I evolved from a Web & UI/UX designer, through a Back-end developer role to the point where I am willing to develop myself as a Full-stack Web Engineer.

I'm able to effectively self-manage on independent projects, as well as collaborate in a productive team to create the most productive result.

I believe in the advantage of a T-shaped specialist who is willing to extend his versatility with a broader range of technologies and disciplines.

I worked a lot with PHP and a little with Java and Python. Today, I'm passionate about ubiquity and flexibility of the Javascript ecosystem.

Participation in all stages of product development - from the prototyping of accessible UIs, building rich cross-platform frontend applications, to the stage of implementation of high-load solutions and application backend architecture drives me strongly.

Executive Summary

  • Over twelve years of experience as Full-stack and Front-end Web Developer;
  • Extensive experience of development with JavaScript (Node.js, Angular/React and TypeScript);
  • Worked with relational (MySQL) and NoSQL (MongoDB, Redis) databases;
  • Hands-on experience in creating complex SQL queries, indexing and (de-)normalization data, replication, stored procedures, and triggers;
  • Good understanding of the concepts of functional programming principles.
  • Knowing the basic principles of object-oriented programming and design (OOP, OOD).
  • Understanding of ideas behind the domain-driven design (DDD);
  • Around one year of experience as a BigData software engineer (Java and GCP);
  • Good working knowledge on Agile methodologies like Scrum/Kanban for software development;
  • Understanding of CI/CD flow, PR/CR approach, Git/GitHub/Trunk Based Development flows. Code analysis, test coverage reporting, coding standards, and quality checking.
Read more About what I am looking for in a job
  • I believe that great projects are created by teams with a high level of mutual trust.
  • Each member of the team must understand "why" behind their "what".
  • Inner motivation is crucial. Ideally, working on the edge of my abilities, keeping the balance between what challenging and boring.
  • Autonomy is just as important. The need to feel confident and in control, an external stimulus should not create pressure.
Read more About my usual role on a team

I am comfortable working either independently (including remotely) or in team projects. I had such an opportunity on my job at Speakap and liked the variety.

A highly productive approach to me is to start a project as a team, brainstorming our ideas, building our deadlines and individual responsibilities before going off to work independently on assigned tasks.

I appreciate the possibility to discuss non-trivial decisions along the way. Knowledge and decision sharing is the key, although I prefer having multiple short (up to 30 minutes) and focused meetings to longer ones since I found them to be more fruitful and fairly short to break the work context.

When working remotely, it's crucial to be able to reach out to a team and it demands a habitual time boxing and a good preparation. I have recent experience with such and have built my procedures and tools which work best for me.

I prefer timeboxing and walling projects to a certain timeframe to make myself more effective instead of allocating the entire day for it.

Read more About a situation where I failed and what I learned from this

A well-remembered failure was the development of a greenfield project at InSkin Media without early delivering of an MVP to the customers. Moreover, it had not enough coverage with automated tests.

As a result, the product turned out to not quite meet certain expectations and required expensive refactoring.

It was complicated because of the absence of sufficient quality control at the initial stages and resulted in extra time and reduced cost efficiency.

Fail fast when it's justified. Extensive testing and incremental development to determine whether an idea has value are important to cut losses and adapt to changes.

An interesting challenge was the improvement of an applications market of the main platform. The applications were communicating with third-party services to provide a seamless single-entry experience for the customer.

Security concerns and storage of users' external data were paramount, as well as the ability to maintain and modify the collection of applications.

Applications worked in separate containers, consisting of common functional modules but having their own configuration, own database and development cycle.

The problem was the development and parallel run on old and new solutions for collecting and processing a large number of HTTP requests (~2000 RPS) for online advertising campaigns and comparing two implementations.

The verification required not only that new implementation gives the same results, but also it operates in acceptable nonfunctional limits, as the number of timeouts and latency.

The R&D team of which I was a member, created a Telemetry service based on CGP service. It was able to accept (App Engine), enqueue and transport (Pub/Sub), log (BigQuery), process (Dataflow), and aggregate (Cloud SQL) incoming data, turning it into a detailed nearly real-time statistics for ad companies.

The two solutions ran side by side and carried out daily reconciliations on the results. The verification process also made sure that calls to the new service are made on time with an acceptable failure rate.

After a few months of parallel run, the Telemetry service was switched over GCP based solution and the old system was retired.

Principles

No silver bullets
Off-the-shelf solutions deliver quick value but add inertia and accidental complexity.

Reduce inertia
Make decisions that favour quick feedback and change while reducing dependencies among teams.

Eliminate accidental complexity
Proactively remove and replace excessively complex processes and solutions so that you can focus on the essential complexity.

Consistent interfaces and data flows
Remove data duplication and create clean systems with consistent integration interfaces

Project Management

Scrum, Kanban
