Books, tutorials & mentoring
Things I wrote down so you do not have to learn them the hard way
Books on growing as an engineer, video courses, and one-to-one mentoring.
Coach: Lead the Right Way
How to find your path to team lead: setting goals, finding resources and planning the steps. My most starred repository.
Stack Overflow The Right Way
The missing manual for taking part in Stack Overflow, Reddit, GitHub and other communities.
Webpack 4the Right Way
Webpack 4 the Right Way
From your first config to a production setup, step by step. More developer-experience tutorials are on my YouTube channel.
Mentoring
Want to talk about your career, a team, or a hard technical decision?
I mentor engineers on ADPList. Book a session to talk about growing into a lead, working with a team, or shaping a product.
Other tools
Built to understand how things work
Open-source experiments in networking and blockchain, made to learn from, not to sell.
Bavin
A real-time packet analyzer that shows network traffic as a stacked TCP/IP protocol view, built to help students see how the layers fit together.
Older Windows utilities and experiments are on Softpedia →
Professional work
What I have built with teams
Over ten years in web products, from trading and messaging to security and developer tools. The short version is below; dates, roles and details are on LinkedIn.
Financial trading web apps
A professional web trading platform, built end to end: watchlists, screeners, transaction timelines, board and chart management, and order-book reliability across the core flows. Plus the backend services behind watchlists and screeners.
Internal business tools
Performance-review, competency-assessment and customer-service apps with 30+ API endpoints and Slack notifications. A Redis cache and a Jira integration with failover made them handle 3x more load at peak, and shared tooling sped up development by 20%.
Real-time messaging
A Telegram-style business messenger built as a PWA, with up to 100,000 users. The hard parts were live updates, sorting contacts efficiently, offline storage, and keeping huge chat histories smooth.
Enterprise security and device management
A firewall management web app with real-time reports, device management for banking systems, and identity and access management. A JSON Schema form generator automated 100% of the very large forms.
Developer experience and team leadership
A starter-kit template that made new projects start up to 40% faster, 70%+ test coverage with unit, integration and end-to-end tests, code reviews, and mentoring of 15+ developers. I have led frontend teams and sat in 50+ interviews.
Imaging and industrial apps
Web front ends for X-ray vehicle scanners, a car-monitoring admin panel for 10,000+ users, a location-based car-assistance service, and a browser library that processes ~30 MB X-ray images, which influenced sales in three countries.
Earlier: security research and teaching
A machine-learning model that predicts software vulnerabilities (over 85% accuracy), real vulnerabilities found in web apps, and university courses on web security, assembly and network programming.
