Software Developer building reliable, scalable web applications.
I help teams and founders ship features faster, reduce technical risk, and keep products maintainable over time.
Founder of R&D EagleLeaf
I’m Krzysztof Sikora — a software developer focused on web applications and long-term maintainability. I approach software engineering with clarity, structure, and ownership of the outcome.
I enjoy building products that need to scale, evolve, and stay understandable over time. I care about clean architecture, thoughtful trade-offs, and collaboration based on trust and transparent communication.
Outside of technology, endurance sports taught me consistency and discipline — the same principles I bring into engineering work: steady progress, clear goals, and finishing what we start.
I help teams move faster without sacrificing quality — from shipping features to improving architecture and reducing technical debt.
Building and improving web apps, implementing features end-to-end, integrations, performance improvements, and bug fixing.
Focus: maintainability, code quality, and shipping value.
Structuring systems for scale: boundaries, modules, data flow, and pragmatic patterns that keep teams productive.
Focus: clear design, fewer bottlenecks, better performance.
Codebase reviews, technical audits, roadmap planning, and focused problem-solving sessions for teams that need a clear direction.
Focus: risk reduction and better decisions.
