Selected work
Featured Systems
Flagship builds - every one ships with architecture, a metric, and source.
Blockchain Inventory System
Problem - Enterprises lose audit integrity when inventory ledgers can be silently edited.
Immutable on-chain ledger + AI demand forecasting
SDG Knowledge Retrieval System (RAG)
Problem - UN-Habitat SDG 11 documentation is vast; teams lose hours searching for citations.
Llama 3.1 + LangChain RAG over vector embeddings, serverless inference on AWS Lambda
Global Climate & Food Security Intelligence Platform
Problem - Food-insecurity early warning is fragmented across siloed datasets and reports.
End-to-end data science platform: ingestion → models → dashboards
Social proof
What partners say
Abridged from written professional references - originals available on request.
“Collins re-architected how our unit handles records - PostgreSQL access was up 30%, ingestion that took days ran in hours after his Python automation, and 2,000+ sensitive files migrated with zero GDPR findings. He treats UN data governance with the seriousness it demands.”
Ms. Alice Ndungu
Supervisor, UNON FMTS Unit
“He migrated 520+ public records to PostgreSQL with zero data loss and cut turnaround by 30%. Beyond the numbers, Collins resolved 150+ tickets across five departments with a 95% first-contact rate - county systems were simply more reliable with him on the team.”
Mr. James Ndegwa
Dept. Administrator, Nakuru County ICT
“Collins kept campus IT infrastructure running dependably and had a rare gift for mentorship - junior technicians and students gravitated to him because he explains systems clearly and hands over documentation that actually works.”
Mr. Victor Rotich
Head of Department IT, PUEA Nakuru Campus
