03Experience

Software Engineer · One Convergence

Feb 2023 — Present
  • Lead engineer on Dkubex, an enterprise GenAI platform — re-architected the RAG pipeline to support hybrid search (vector + BM25) and multimodal ingestion.
  • Drove Dkubex 2.0, a platform revamp on Kubernetes: Helmfile-managed multi-service deployments, Gateway API + Traefik routing, OAuth2-Proxy for unified auth.
  • Cut container image size 80% (10 GB → 2 GB) and lifted serving throughput 2×+ (30 → 50–80 req / GPU) through profiling and Langflow integration.
  • Stood up ClickHouse / HyperDX / ClickStack observability — measurable MTTR reduction on inference-path incidents.

Digital Specialist Engineer · Infosys

Aug 2021 — Feb 2023
  • Full-stack delivery on enterprise React + Node.js applications.
  • CI/CD authoring on GitHub Actions; introduced container-first workflows to client teams.

B.Tech, Mechanical Engineering · Vishnu Institute of Technology

Enterprise GenAI Platform

Dkubex

Lead engineer on a RAG-first GenAI platform: hybrid search, multimodal ingestion, Langflow-driven flows, OAuth2-unified auth.

  • ▸Re-architected ingestion → retrieval → generation pipeline end-to-end
  • ▸Hybrid search (vector + BM25) lifted top-k relevance on internal eval set
  • ▸2×+ serving throughput per GPU through batching + scheduler tuning

Next-Gen Unified Architecture

Dkubex 2.0

Multi-service Helmfile + Kubernetes deployment with Gateway API + Traefik routing and ClickStack observability across the inference path.

  • ▸Cut container image footprint 80% (10 GB → 2 GB) via base-image audit + multi-stage builds
  • ▸Single-pane observability across services with ClickStack
  • ▸Gateway API migration unblocked per-route auth + rate-limit policies

LLM Gateway Platform

SecureLLM

Independently designed and built an LLM proxy gateway with dynamic multi-provider routing and API key abstraction for tenant isolation.

  • ▸Provider-agnostic routing across OpenAI / Anthropic / Azure
  • ▸Tenant-scoped key vaulting; upstream keys never reach the client
  • ▸Per-tenant usage + cost telemetry from day one
