Impact

~400 hrs

saved per quarter

Data-quality validation catching defects before ingestion.

40%

faster page loads

Refactoring and Redis caching on the Domain Data Middle Layer.

5+

teams adopted

Shared Angular component library with cross-team governance.

Days → hours

data ingestion

Automated external ingestion, removing 3–5 manual steps.

Featured projects

Data intelligence, architecture intelligence, API resilience

Three projects that define my work — with ownership labelled clearly for each.

01Individually Architected

TAG (Table-Augmented Generation)

Enterprise Data Intelligence

Natural language → executable enterprise data intelligence. Business and domain data teams ask questions in their own terms; TAG resolves entities, discovers schema relationships, generates and validates SQL, runs it and recommends data actions.

TAG · Table-Augmented Generation

01 Business question

"Which regions in the upcoming release are missing rate records compared with the current production set?"

→ Intent: compare release vs. production

→ Entity: rates by region

02 Relevant tables

regionrate_headerrate_detail

03 Generated SQL

SELECT r.region_cd
FROM region r
LEFT JOIN rate_header h
  ON h.region_cd = r.region_cd
 AND h.release_id = :next
WHERE r.active_flg = 'Y'
  AND h.rate_id IS NULL;

04 Query result

  • REG-04missing
  • REG-11missing
  • REG-17matches

05 Recommended data action

For team review: rate_header, rate_detail for REG-04, REG-11

02Collaborative FDE Project

Architecture Intelligence from GitHub

Forward Deployed Engineer Program · Collaborative Project

A GitHub-connected architecture intelligence solution that analyzes application repositories, generates the current-state architecture, and suggests architecture updates for new features and technology upgrades.

Self-Healing API Clients with Tiered Routing

M.Tech Research · Software Engineering

Designed and evaluated a framework for resilient API interactions under runtime schema/API changes using LLM reasoning and tiered routing — validated with a 50-case automated evaluation.

  1. Schema change
  2. Failure detection
  3. Classification
  4. Tiered routing
  5. LLM reasoning
  6. Transform / cache
  7. Resilient call
