I'm Simon Waiblinger (simwai, or Wobby to some), a full-stack developer working from Vorarlberg, Austria, who has spent the past five years building systems that prioritize reliability and velocity in roughly equal measure — though the balance shifts depending on whether I'm maintaining production systems under pressure or prototyping a new trading algorithm. My frontend work centers on Vue and Angular — Vue for its pragmatic approach, Angular for enterprise applications (especially with .NET backends) where sustained development investment justifies the framework's complexity. Backend work spans Node.js and .NET ecosystems.
Much of my work involves automation in its various manifestations: trading bots that execute strategies without human intervention, scrapers that extract signal from noise, and algorithms that compress complexity into manageable abstractions. I've also devoted substantial energy to building business pages using headless CMS or WP. Statistical analysis in Python rounds out the toolkit, transforming raw data streams into actionable insights through proper quantitative methods.
My architectural philosophy derives from pragmatic experience rather than dogmatic adherence to any single paradigm. Clean Code principles, the Law of Demeter, and strategies like KISS and DRY inform daily decision-making, while patterns like Observer, Strategy, and Command provide structural scaffolding when complexity justifies abstraction. I favor explicit dependency injection over framework abstractions when transparency matters, composition over inheritance wherever feasible, and alignment with CUPID and SOLID principles as conceptual guides rather than rigid constraints. The Agile Manifesto's emphasis on working software over comprehensive documentation resonates, though I interpret this as "documentation follows understanding" rather than "skip documentation entirely".
System reliability demands attention to failure modes that many developers ignore. I build graceful shutdown mechanisms into every long-running process and implement fail-fast logic that exposes problems immediately rather than allowing them to propagate through layers of abstraction. Modern codebases suffer from two opposing pathologies: excessive exception throwing that drowns signal in noise, and silent fallbacks that swallow failures until debugging becomes archaeological excavation. The correct approach makes errors visible, actionable, and traceable without creating so much logging overhead that production systems become unreadable observability nightmares.
Regarding AI-assisted coding: I use LLMs as a tool to support a faster realization of my visions. I work with coding assistants as well as agents. I know these tools are not super reliable, but I already accomplished working projects with significant higher speed, so I try to master this and squeeze out the most reliable code I can get although this doesn't work for each project especially. Sometimes, any agent just suck and then you have to go into the battle with only your coding assistant and the docs equipped.
My open-source contributions include a merged PR to npm-packlist that improves debugging output for 20+ million npm users, potentially saving thousands of developer-hours daily through better error visibility in the packaging pipeline. I authored the PowerShell deployment automation script for freqtrade (a trading bot with 30k+ GitHub stars) and implemented scheduled cooldown reset functionality that prevents strategy exhaustion during volatile market conditions.
Outside software development, I maintain balance through physical and contemplative practices. Taekwondo training builds kinesthetic awareness and focus, meditation practices (mudras, Qi Gong) develop body-mind integration, and gym work provides straightforward feedback loops between effort and result. Winter brings freeriding opportunities, vacations typically involve coastal environments, and I practice shuffle and hip-hop dance styles as creative outlets. Swimming serves both athletic and meditative purposes. Alpha wave music maintains flow states during extended coding sessions. Gallery visits, concerts, and social events provide exposure to perspectives outside the technical bubble, while family time, nature exposure and laughter keep me grounded in reality rather than pure abstraction.
I draw intellectual inspiration from Salvador Dalí's surrealist work, which demonstrates how constraint violation can reveal deeper structural truths, and from developers like sindresorhus (TypeScript craftsmanship) and xmatthias (Python technical depth) whose code exemplifies clarity without sacrificing power.
