-
Jun 2023 – Jun 2026 Software Development Engineer 1
IQVIA
- June 2023–June 2026. Backend engineer on IQVIA's KPI Library, the dynamic reporting layer within Orchestrated Analytics, working across configuration, dashboard, analysis, and export workflows for healthcare analytics. Built and maintained C#/.NET services, data-access components, automated test infrastructure, and a schema-grounded AI copilot with supporting evaluation, retrieval, security, and observability infrastructure.
- Built and maintained C#/.NET services and shared components across four KPI Library workflow areas—configuration, dashboard, export, and gateway; used EF Core with SQL Server for configuration data, MongoDB for dashboard caching, and AWS S3 in export workflows
- Refactored repeated filter-resolution logic into reusable query components, consolidating 6 duplicated implementations into 2 shared components; centralized validation and business rules and added regression scenarios for combined filters and edge cases
- Added in-memory caching to targeted .NET read paths and improved interaction with the MongoDB-backed dashboard cache, reducing MongoDB reads per warm request from 4 to 1 and p95 latency from 420 ms to 340 ms across 500 equivalent warm requests per benchmark run
- Extended two export paths—CSV and presentation exports—with regional-formatting and commentary support; increased automated high-risk export scenarios from 28 to 46 and reduced pipelines requiring a flaky rerun from 12 of 100 to 4 of 100 comparable export-test runs by controlling fixtures, locale, and browser state and normalizing volatile file metadata before hashing stable content
- Implemented server-side axis-break resolution for KPI charts by computing adjacent gaps in ordered KPI values and translating qualifying intervals into Highcharts yAxis.breaks, keeping visualization behavior consistent across clients
- Reorganized three CI stages, build, test, and packaging; ran independent test suites in parallel and reused build artifacts between stages, reducing median successful-pipeline duration from 24.5 to 20.3 minutes across 25 comparable runs before and 25 after the change
- Contributed OpenTelemetry/Jaeger instrumentation and correlation identifiers across 8 named API, database, and cache operations in three workflow areas—dashboard, configuration, and export—making cross-service calls and database latency visible during debugging
- Designed a schema-grounded dashboard copilot that compiled analyst requests into versioned, permission-scoped operations for KPI selection, filtering, comparison, visualization, commentary, and export; validated and previewed each plan before approval, executed it idempotently with concurrency and rollback safeguards, then verified the final state and recorded an audit trail, improving exact requested-state completion from 65% to 87% and reducing invalid committed changes from 8.1% to 0.9% on a 350-workflow held-out subset of the agent benchmark
- Built a 400-workflow agent evaluation platform with trace replay, deterministic state and business-rule graders, numerical and export assertions, human-calibrated narrative scoring, multi-trial execution, and CI release gates; caught more than 20 prompt, model, retrieval, and tool-schema regressions before rollout and reduced candidate-model qualification from five days to one
- Developed an evidence-grounded KPI investigation assistant combining deterministic calculations, anomaly detection, hierarchical driver analysis, and source-linked narratives; increased numerical claims matching computed evidence from 91% to 98.7%, reduced unsupported analytical statements from 12% to 3%, and cut median investigation time from 13 to 7 minutes on an expert-reviewed task set
- Built a policy-enforcing execution gateway with capability-scoped authorization, tenant and market propagation, sensitive-data redaction, approval workflows, untrusted-content isolation, and immutable provenance; observed zero unauthorized executions across 5,000 adversarial cases while keeping benign-task false blocks below 2%
- Developed tenant-, permission-, and version-aware hybrid retrieval over KPI definitions, calculation rules, dashboard templates, and operational knowledge using lexical and embedding retrieval, reranking, effective-date filters, structured lookups, versioned citations, and calibrated abstention; improved Recall@5 from 0.76 to 0.93, citation precision from 84% to 97%, and reduced stale KPI explanations from 12% to 3% on a held-out retrieval evaluation
- Built an observable, provider-neutral model gateway with versioned prompts and models, complexity-aware routing, scoped caching, cost budgets, bounded retries, circuit breakers, fallbacks, shadow evaluation, and end-to-end AI traces; reduced p95 validated-response latency from 17 to 9 seconds and cost per successful workflow by 42%, while keeping candidate-model task success within one percentage point of the baseline model
- Received the IQVIA Impact Program - Silver award in May 2025
