Message

At LMKR, I work on Halliburton’s PetroHive and PetroBank enterprise data platforms. On PetroHive, I built a sequential import pipeline to prevent skipped records and designed concurrent processing with user-scoped session isolation.

I also led PetroHive’s bidirectional integration with GVERSE and built a warehouse management module. Before LMKR, I developed financial platform features at MoneyPex and payment integrations and an AI surveillance platform at A1 Global Technologies.
