Work History
Senior Software Engineer
Perceptive Informatics LLC (formerly Invicro)
01.2025 - 02.2026
- Led the frontend architecture and contributed to the broader system design for a Pre-Sales Portal built with React.js, TypeScript, and Golang that consolidated a fragmented R&D operations process (Excel, SharePoint, Salesforce) into a single data-integrated application, streamlining workflows for sales, science leads, and pricing teams.
- Contributed to enterprise data lake development using AWS data pipelines (Glue ETL, Lambda-based orchestration, Athena) for ingestion, normalization, and analytics across high-volume scientific data sets.
- Applied hypothesis-driven development methodology, operating as an internal consultant to identify pain points, bottlenecks, and inefficiencies in R&D workflows before building solutions.
- Led the frontend architecture and contributed to the broader system design of a consolidated medical imaging review tool, while building large portions of the full-stack application. Centralized fragmented R&D workflows (submission review, data selection, PHI checks, compliance checks) into a single interface, achieving a 57% throughput increase without additional headcount, and earning a 9.0/10 ease-of-use and 9.1/10 satisfaction rating across all application views.
- Led frontend architecture: evaluated and selected the React framework (Vite vs. Next.js), configured TypeScript, selected Material UI, designed the application structure, and implemented AWS-hosted serverless infrastructure via IaC.
- Designed and built RESTful APIs using API Gateway and Lambda, coordinating multiple independent services each with their own database (DynamoDB and PostgreSQL via RDS/Aurora), using Python, SQLAlchemy, and Alembic for reliable data integration and workflow automation.
Software Engineer
Perceptive Informatics LLC (formerly Invicro)
10.2019 - 01.2025
- Created a reusable AWS serverless template (Serverless Framework v3): React/TypeScript build synced to S3, delivered through CloudFront, backend APIs via API Gateway + Lambda, all defined as infrastructure-as-code with one-command deployment. Reused across multiple projects.
- Designed and implemented the data model and database schema across multiple databases (RDS and Aurora with PostgreSQL) using the Serverless Framework, with migration management via SQLAlchemy and Alembic.
- Implemented Datadog RUM (Real User Monitoring) for production application observability.
- Wrote comprehensive tests in Python and TypeScript (Jest) to ensure code quality and reduce regressions.
- Partnered closely with UX, product, and scientific stakeholders to translate complex requirements into intuitive user interfaces.
- Built a React form generator to support existing iPACS forms and form functionality, enabling consistency between the legacy and new systems.
- Served as sole engineer operating as tech lead on iPACS product releases, including the 3.5.0 release that reduced operational costs by ~$250K annually through targeted UX improvements, improving per-image task efficiency by 3x and raising user satisfaction by 31%; scoped features, built technical design proposals with trade-off analyses, coordinated with stakeholders, and delivered end-to-end.
