What I'm looking for

I’m looking for a role where I can build and evolve C++ platforms that must be real-time, reliable, and operationally transparent—ideally involving media streaming, infra control planes, or AI infrastructure, with room to lead technical direction.

I’m a C++ software engineer focused on building production-grade platforms for real-time media, cloud infrastructure, and large-scale AI services. I enjoy turning complex requirements into maintainable systems—especially when performance, reliability, and operational clarity matter.

At Scalstrm AB (Sweden), I extend a just-in-time Live/VOD transcoding extensions system (plugins) to analyze and modify video/audio frames (blackout, watermark, deinterlace, frame repair...). I’m currently working across modern C++ and media streaming formats like HLS and DASH to keep pipelines efficient and dependable.

Previously at Net Insight AB, I developed and maintained the data plane for Nimbra Edge ⮺, including multi-program transport stream splicing for ad insertion via SCTE-35 messages. I also handled MPEG-TS parsing/generation and maintenance for RIST/RTP/SRT/HLS protocol support, with a strong emphasis on correctness and long-term support.

At Rakuten Inc., I led the design and implementation of a new Virtual Infrastructure Management control plane (Tech & Team lead), adding VPC for isolated tenant networking and building an extensible entity model and decentralized reconciliation engine. Earlier, I worked across Global DataScience/Advanced Computing platforms and AI application infrastructure (MLOps, Kubernetes, distributed storage), and I also delivered mission-critical systems in trading, simulation, and high-availability services—always bridging architecture, engineering, and operations.
