SENIOR DATA ENGINEER · AMAZON

Abhijit
Krishna Menon.

I build data platforms,
and put AI to work.

From self-service analytics to engineering tools and customer-facing software.

01 / PLATFORM ENGINEERING

Analytics that teams can extend.

I set up the platform and agent harness; 50+ contributors built its domain context and SQL tools.

My contribution
Platform setup and engineering of an extensible analytics harness, with custom SQL-based tool onboarding. Contributors supplied domain context and SQL tools.
What it supports
MCP integrations, code interpreters, evaluations, intent and sub-topic routing, retrieval over a knowledge base, and safe, access-controlled answers. The React portal and Python backend support charts, reports, and self-service analytics.
Making it usable
Self-service onboarding of business domains, sources, and knowledge articles, alongside authoring, testing, and CI tooling for skills and topics. Systematic evaluations replaced manual log inspection for quality measurement.

02 / DATA + PRODUCT ENGINEERING

From disputes to prevention.

I built the analytics, enabled self-service, then shipped portal changes and entry validation.

Read the case studyClose details
Starting point
The program had no analytics around this workstream. I defined metrics, built Redshift models and pipelines, and created reporting that helped operations and BI partners see where excess dispute volume concentrated and what drove it.
Following through
When partner teams lacked capacity for needed product changes, I worked in the customer-facing portal and shipped UI updates and an automated point-of-entry validation gate.
What changed
The work progressed from analysis and recommendations to self-service visibility and a production control. My ownership crossed the data, backend, and frontend boundaries needed to deliver it.

03 / ENGINEERING WORKFLOWS

Less manual work. More signal.

Purpose-built AI tools for database exploration, query review, and incident investigations.

Explore
Built a Redshift MCP server for schema discovery, query execution, and performance diagnostics. Its secure proxy and identity layer support per-agent identity, audit provenance, and permission guardrails.
Review
Built an agent that executes pull-request SQL against Redshift, parses EXPLAIN plans, and surfaces syntax errors and optimization recommendations before merge.
Investigate
Built an autonomous on-call agent for ticket triage, parallel investigations, root-cause analysis, and automatically posted findings.
Further work
A voice-enabled coaching and learning agent turns performance data into spoken briefings. Reusable permission and ticketing frameworks support multiple applications.

04 / EXTERNAL PARTNERS

AI beyond the engineering team.

I contributed to DSP Companion, Amazon’s AI assistant helping Delivery Service Partners run their operations.
