Current & Upcoming Innovations
Autonomous Career Concierge
A production AI agent that answers recruiter questions about my career 24/7 — deployed on AWS and live on this site. Powered by Claude Haiku 4.5 via Amazon Bedrock, it retrieves answers from 22 career documents spanning 16 years of experience, including the 53M subscriber HLR migration.
- RAG Pipeline: Parallel S3 document retrieval across resumes, STAR responses, and CDR episodes — 150K token context window.
- Enterprise Guardrails: Bedrock content filtering (hate, violence, prompt injection) + PII anonymisation deployed to production.
- Full IaC: API Gateway → Lambda → Bedrock pipeline fully provisioned via Terraform with CI/CD on GitHub Actions.
Role Fit Analyzer
Paste any job description and get an instant semantic match score against my profile — broken down by skill domain. Powered by AWS SageMaker Serverless Inference running all-MiniLM-L6-v2, with zero idle cost.
- Zero-shot Semantics: No training data — cosine similarity on sentence embeddings, computed at inference time.
- Serverless Inference: SageMaker scales to zero between requests — no idle compute cost.
- Full IaC: SageMaker endpoint, Lambda scorer, and API Gateway fully provisioned via Terraform.
AI Ops Command Center
Real-time observability dashboard monitoring live AI services — usage analytics, feedback loops, system performance, and cost tracking across SageMaker and Bedrock. The ops layer that makes AI systems production-worthy at enterprise scale.
- Live Observability: Real-time metrics from SageMaker and Bedrock — usage trends, match score distributions, domain heatmaps, and invocation latency.
- Feedback Intelligence: Closed-loop analytics connecting recruiter responses to model performance signals — accuracy trends, gap categories, and score drift.
- Cost & Performance: Estimated cost per analysis, Lambda error rates, API health, and DynamoDB throughput — all in one private admin view.
GenAIOps: Governance-as-Code Framework
Scaling AI safety with an automated framework for GenAIOps. This project focuses on injecting security governance and cost-attribution directly into CI/CD pipelines, enabling enterprises to deploy LLM-backed services with confidence.
- Guardrail Automation: Programmatic deployment of content filters and safety policies via Terraform.
- Self-Healing Infrastructure: AI-driven log analysis to autonomously propose and apply infrastructure remediation.
