Mastering Feature Flags: A Guide to Controlled Rollouts
"Mastering Feature Flags: A Guide to Controlled Rollouts" offers a deep dive into the strategic use of feature flags in software. Learn how to categorize and manage feature flags, navigate their lifecycle, and balance the benefits and risks. Ideal for architects, developers, product managers, and business leaders aiming for safer deployments, streamlined testing, and agile responses to market changes.
Scale your front-end with plug-ins
As projects grow bigger and with more features over time, companies are facing increasing code complexity. I am going to be talking about solving different challenges on the front-end, coming out of the increased scale of a software system.
What is a plug-in? Do we need decoupled front-ends? How do we design a system that scales both on production and during development? Can we achieve high cohesion and low coupling on the web, with JS? In this talk I am going to be answering many of these questions.
The technology stack presented is going to be: TypeScript, React, MobX, and the tooling to support them.
The mythical senior developer
A story about the never ending professional journey,
alcohol, unicorns, cynicism, egos, bubbles,
and hurt feelings.
Why copy/paste practices are not going to make
you invaluable, but thinking and working hard would.
In this talk we are going to explore the habits
that make or break professionals.
Abstraction 101
All developers talk about abstraction. And we often hear that it is observed in the wild. We hear that software architecture and development are all about abstraction.
In this talk we are going to explore some of the questions we face in the very early stages of our professional development:
- What is an abstraction?
- What is the wrong level of abstraction?
- What is the right level of abstraction?
- How do you know if you are doing it right?
This talk is suitable for people in different levels of their career development. Based on your level you are going to hear and understand different aspects of abstractions. It is also suited for beginners who struggle to grasp one of the most important concepts in programming - abstraction.
Github Copilot vs Reality
"GitHub Copilot vs Reality" is a 15-minute lecture designed to delve into the intersection of AI and software development. The session kicks off with an introduction to the role of AI in coding, followed by a quick primer on the GPT model that fuels GitHub Copilot. Attendees will gain insights into Copilot's features, capabilities, and limitations. The lecture will also address the gap between Copilot's theoretical promises and its real-world performance. Wrapping up, the talk will cover crucial topics like intellectual property and licensing issues. The aim is to offer a well-rounded view of GitHub Copilot and its impact on the software development ecosystem.
The hidden reality of software economics: Demystifying TCO
In this talk, "The Hidden Reality of Software Economics: Demystifying TCO," we delve into the complexities of Total Cost of Ownership in software development. The session is designed to provide a comprehensive understanding of the various cost factors beyond initial development, including maintenance, compliance, security, and decommissioning.
Goals:
- Explore the full range of software development costs.
- Question common assumptions about software solutions and architectures.
- Highlight often overlooked aspects of software economics.
- Discuss the balance between cost reduction and maintaining quality.
Session Overview:
- Analyze real-world examples to understand TCO dynamics.
- Offer insights into effective cost management strategies.
- Facilitate discussions on the intricacies of software project costing.
- This session is aimed at professionals in software architecture and project management, focusing on an informed approach to managing software project costs.
Performance 101
Everything you know about software performance is probably wrong… Performance is a business metric. Yes - how fast your web site or service is loading/responding is a business requirement. In this talk I am going to cover: - what, why, and how should be measured - what are some of the possible root causes for poor performance

So, you think you do quality assurance?
Who is responsible for quality assurance or who executes the quality assurance function in the team? Are they doing quality assurance or control? Join me in this one to find out what is the essence of quality assurance and what kind of development process you need to deliver without defects.
Lessons learned: WebSockets
I've been using WebSockets on production in a large scale system for the past 5+ years. In this session I am going to share variety of challenges I've personally dealt with and some of the ways on how to overcome them. If you'd like to know how to design application that can take advantages of WebSockets when you have a microservices and APIs based back-end, that's the talk you've been looking for!
Topic includes:
- What are WebSockets?
- Architectural and technological challenges.
- Protocols.
- Performance.
- Load balancing.
- Alternatives to WebSockets.
[WORKSHOP] Designing software with volatility based decomposition Vol 2.0
Problem decomposition - often, requirements come as an explanation of how to get to some result. We will discuss how to approach them so that the team can break down more complex problems into combinable components/services. Topics to be covered include:
- Divide and conquer
- Volatility-based decomposition (based on frequency or potential for change of the component)
- Devil's advocate approach to challenging design decisions
# Goals
- Learn how to identify areas of volatility and how to design to contain them.
- Highlight how different perspectives affect the solution to the same problem and how to take advantage of it.
- Define a common framework for clearing out requirements and identify solutions hiding behind the label "requirement."
# Process
The group will be split into teams of 2-3 people who will work with a customer to extract requirements based on a loose definition of a project. Each unit is time-boxed to complete specific objectives and present them to the other teams, where the entire group will digest and challenge the different solutions.
# Prerequisites
- Whiteboards
- Flipcharts
- Pens and paper
# Preparation for the participants
No prerequisites for the participants.
Small optimizations for critical decisions
Martin is going to share lessons learned from a decade of developing and maintaining a large scale system that deals with streaming near real-time updates to the end users.
This one is about the small things engineers do day to day that could have big impact down the road but sometimes could get neglected.
A day in the life of an architect
Ever wondered how the digital world's foundations are laid?
In this interactive session, we'll unravel the mystery of the Software Development Life Cycle (SDLC) and reveal why it's crucial to every organization. Gain insights into the architect's position within a team, their technical responsibilities, and how they bring innovative ideas to life. Discover the pivotal role software architects play in shaping the technological landscape and how their decisions impact businesses and organizational structures.
This talk is a deep dive into software architecture, the SDLC process, and the responsibilities of the architecture role. It is suitable for all aspiring architects, tech enthusiasts, and curious minds: don't miss this opportunity to explore the dynamic world of software architecture and learn how to harness your potential in this ever-evolving field.
