Krom Analytics
Field data, price monitoring, and market intelligence for Ghana's informal markets.
John Sena
Akoto
I build reliable systems for compute and data, with a growing focus on AI infrastructure, GPU clusters, distributed platforms, and market intelligence.
I am a software engineer at Oracle. My path runs through geophysics, scientific computing, and cloud systems; lately, it also includes Krom Analytics, a data initiative for understanding Ghanaian markets from the ground up.

01 · About
Infrastructure, reliability, observability at scale.
I like work where the details matter: scheduling, reliability, performance, data quality, and the messy last mile between an idea and a system people can actually use.
02 · Work
What I build
My current center of gravity is AI infrastructure: compute environments, schedulers, distributed systems, and the tooling around large workloads.
Slurm cluster automation
Provisioning, configuration, and validation work for distributed compute clusters.
AI infrastructure · scheduling · shell
Distributed systems foundations
Multi-threaded secure messaging with confidentiality, integrity, and non-repudiation.
Java · systems · security
Machine learning workflows
Notebook-based model development and evaluation, useful context for the workloads AI infrastructure supports.
Jupyter · ML · data
Scientific computing roots
Wavefield iterative deconvolution for seismic imaging research.

03 · Outside work
Side quests
A few threads that make the work feel like mine: public-interest data, the learning loop around AI systems, and life away from the keyboard.
Learning loop
AI infrastructure, GPU scheduling, Kubernetes-native platforms, and systems that make compute useful.
Outside work
Tennis, gardening, houseplants, volunteering, and mentoring students through CodePath.
