About
Hi, I’m Marko Kalasan. I specialize in backend and frontend engineering, cloud infrastructure, and building scalable systems. I’ve led a small team at Wolfware Labs, designing network/back-end architectures, IAM, CI/CD, and blue-green deployments, delivering high-performance apps with AWS, Bun, and SvelteKit.
I enjoy tackling tough problems like end-to-end encryption and video encoding pipelines, collaborating with designers on UI/UX, and mentoring peers. I’m excited about new challenges in software engineering and product development.

Work experience
Led a small backend/web team and built greenfield cloud/network infrastructure with IAM, GitOps, Notion/JIRA triggers, env isolation, blue-green deploys, and backups. Shipped high-performance apps on Bun/SvelteKit/SQL/AWS and ran zero-downtime Firebase -> AWS migrations. Created internal codegen (incl. a Swift client for tRPC, later open-sourced). Solved hard problems like fintech-grade end-to-end encryption and a self-hosted 4k60 video encoding/editing pipeline.
Worked on several SwiftUI and UIKit projects in a team of developers. Closely collaborated with designers to tackle UI / UX challenges and offer feedback from an engineering standpoint. Worked on MSL shaders for custom camera filters for the companion app to a Netflix show
