Professional experience
Founding Engineer · Brekfuz
– Present
- Built the answering layer of a knowledge platform, resolving source permissions before generation so one answer splits by clearance rather than leaking or over-restricting.
- Held the tenant boundary in the database rather than in application code, with the services verifying it against the live catalogue at boot and refusing to start without it.
Founding AI Engineer · Hey Amara
–
- Moved the agent platform's message-queuing layer off Redis and onto RabbitMQ, reworking the circuit breaker, gateway, orchestrator and service launcher around durable messages.
- Built the conversation compaction that holds a long thread inside its token budget by summarising earlier turns into a validated schema rather than prose.
Applied AI Engineer · UltraSafe AI
–
- Built a seven-layer extraction pipeline running six engines in parallel over clinical documents and reconciling their disagreements by vote.
- Built a four-stage retrieval pipeline fusing dense, SPLADE sparse and ColBERT representations, and deployed it on Kubernetes with tracing across the request path.
Founding AI Engineer · Munshot
–
- Built an MCP-compliant tool server putting more than ten data sources behind one contract, so the reasoning layer never carried provider-specific code.
- Built a fifteen-node LangGraph reasoning engine with recovery inside the graph, so a malformed provider payload degrades one branch instead of ending the run.
