Dipl.Ing.
Peter Hasitschka
Senior Fullstack Developer & Technical Lead
Building high-performance web and mobile products, leading teams, and designing the agentic workflows that make both faster.
Core Disciplines
Where I create the most value.
Full-Stack Product Development
Building complete digital products from the ground up — database, backend, and polished frontend UI.
Technical Leadership & Architecture
Guiding teams and designing robust, maintainable system architectures.
Agentic Workflows & Automation
Designing and integrating agentic AI systems — custom MCP servers, context engineering, and multi-agent orchestration.
Mobile App Development
Building cross-platform native apps with React Native — from architecture to App Store.
My Toolbox
Technologies and practices I use day-to-day.
AI & Agentic Coding
Designing and operating agentic systems — from model APIs and structured context to multi-agent orchestration and team rollouts.
Programming Languages
My multi-language skill set lets me apply the right language and ecosystem— from quick prototypes to data-heavy back-ends and performance-critical modules—exactly where each project’s requirements demand it.
Frontend
I translate complex business ideas into fast, accessible and search-friendly interfaces that scale from MVP to enterprise portals.
Backend
Clean architectures, strong typing and thoughtful data modelling keep server logic maintainable, testable and ready for heavy traffic.
Mobile & Desktop
Shared codebases power native-feeling apps across iOS, Android and desktop while shortening release cycles and ensuring UX consistency.
APIs & Messaging / Authentication
Robust, real-time communication and solid auth keep data flowing securely between microservices, devices and end-users.
DevOps & Cloud
Automated pipelines and container orchestration turn code into resilient cloud workloads with zero-downtime releases and clear observability.
Testing & Quality Assurance
A test-first mindset, continuous monitoring and actionable metrics bake quality into every commit and deployment.
Dev-Tools
Efficient build systems, modern package managers and collaborative IDE workflows keep delivery fast and developer focus on business value.
Methodology & Soft-Skills
Agile leadership, continuous improvement and clear bilingual communication align teams and stakeholders around impactful outcomes.
AI in Practice
How I apply agentic tooling — in practice, not just in theory.
Custom MCP Integrations
Building MCP servers that give AI agents direct, structured access to internal APIs, project management tools, and company-specific data — so the AI works with real context, not guesses.
Context Engineering & AI Memory
Designing persistent context systems (memory files, structured prompts, skill libraries) that make AI assistants actually reliable across sessions — not just impressive in demos.
Team Rollout & Agentic Coaching
Embedding agentic workflows into real dev teams — structured AI context setups, custom skills/commands, and multi-agent orchestration. Not just using AI — multiplying it.
