Vapusdata
Jun 2026 — Aug 2026

Vapusdata

Intern
  • Architected and built an end-to-end enterprise Prompt Contract system using Protocol Buffers, gRPC, and Bun.
  • Designed a multi-layered architecture following Separation of Concerns for scalable AI prompt management, split into five focused layers.
  • Prompt Contract (Library) — source of truth storing immutable prompt specs, templates, and system messages as large JSONB.
  • Prompt Contract Grid (Topology) — maps UI modules/components to prompt IDs and generates strict VRN identifiers.
  • Prompt Contract Grid Search (Discovery) — lightweight table with pgvector + tsvector for fast cosine similarity and full-text search without scanning large JSONB.
  • Prompt Contract Ranking (Telemetry) — separate high-write table for tokens, retries, errors, and model metrics to avoid locking config data.
  • Vapusfin PromptContract (Router) — maps actions to preferred prompt versions for safe rollouts and A/B testing.
  • Supported two execution paths: a dynamic AI agent flow (user query → embedding search → grid lookup → library fetch) and a direct UI flow (button action → router lookup → library fetch).
  • Enabled zero-downtime version rollbacks by updating version pointers instead of deleting prompts.
  • Isolated heavy JSONB (TOAST) from vector/search indexes for faster queries and lower database load.
  • Implemented a full feedback loop so ranking data could be used later for prompt performance evaluation.
Kubernetes & Cluster API
Jan 2026 — present

Kubernetes & Cluster API

Open Source Contributor
  • Fixed a goroutine leak in TestNodeSyncResync by correctly handling the opChan lifecycle, preventing test hangs in core Kubernetes. [PR #135217]
  • Resolved flakiness in TestROSANetworkReconciler (CAPA / AWS provider) with Eventually assertions. [PR #5861]
  • Updated Cluster API controller to remove finalizers during deletion when ownerRef was never set. [PR #13239]
  • Added Kubernetes Events for automatic certificate rotation in KubeadmControlPlane. [PR #13242]
  • Proposed maxRetry for RemediationStrategy in MachineDeployments to align with KCP remediation. [Issue #12553]
GitLab Terraform Provider
2024 — present

GitLab Terraform Provider

Open Source Contributor
  • Refactored token rotation into a shared RotatableToken interface across Project, Group, Personal and Service Account tokens. [MR !2894]
  • Implemented gitlab_project_security_settings resource for automated security management. [MR !2897]
  • Fixed wiki subpage title drift and special-character slug handling. [MR !2896]
  • Hardened DetermineExpiryDate to return proper validation info, preventing segfaults across all token resources. [MR !2722]
  • Made project label renames in-place via numeric ID mapping instead of full resource replacement. [MR !2719]
  • Built artifact-file data source to download text and binary CI/CD job artifacts through Terraform. [MR !2721]
  • Added group service account token data source, package dependency proxy resource (GraphQL), label priority support, and compliance requirement resource. [MR !2805 +]
  • Added gitlab_compliance_requirement resource for managing Compliance Framework Requirements and Controls (Ultimate) via GraphQL. [MR !3178]
