Work History
Senior Software Engineer
Mimecast
Lexington
07.2025 - Current
- Led Java backend architecture and implementation across APIs, Postgres schema design, Liquibase migrations, scheduler workflows, release coordination, and production debugging for Mimecast Engage across self-hosted and AWS-hosted environments.
- Implemented nearly all backend work for a 2026 Engage campaign redesign, including legacy-to-new-model migrations, Postgres/Liquibase schema changes, and Java logic supporting per-campaign customization while preserving legacy campaign behavior in the same codebase.
- Re-architected campaign configuration and delivery logic to support notification overrides, release strategies, due-date policies, cadences, and per-campaign targeting across active-active database clusters in a multi-grid production topology.
- Coordinated cross-team backend designs from API contract through implementation, launch, and troubleshooting with frontend engineering, DevSecOps, product, and customer-facing support teams.
- Mentored several colleagues moving from support into development by advising on technical learning paths, engineering habits, and areas of focus.
Software Engineer II
Mimecast
Lexington
10.2022 - 07.2025
- Built nearly all Java/API backend functionality for Engage Human Risk Scorecards, including a standalone AWS-hosted API service supporting generated email content, scorecard data, previews, templates, risk breakdowns, and campaign scheduling workflows.
- Designed the User Scorecards API contract and partnered with frontend engineering to support admin and end-user previews, customization, template management, and asynchronous delivery workflows across all Mimecast regions.
- Built asynchronous processing flows using DynamoDB for event logging, scheduled discovery of unprocessed jobs, and SQS-triggered execution for enterprise customers with up to 10,000 users at a time.
- Redesigned campaign processing to avoid inefficient per-campaign loops across hundreds of campaigns per customer per cluster, supporting concurrent handling across hundreds of customers per region.
- Used Cursor, Claude, and Codex for code analysis, debugging, boilerplate generation, test generation, and identifying edge cases, validations, and defensive strategies.
QA Engineer II
Mimecast
Lexington
05.2020 - 10.2022
- Built Java-based manual and automated API testing practices while participating in API on-call and deployment rotations, creating a foundation for later backend engineering ownership.
- Used database queries, internal reporting, and telemetry analysis to validate API behavior and inform product changes across Ataata, Awareness Training, and Engage.
- Helped integrate Ataata into Mimecast by combining Level 3 support knowledge with QA/API testing experience, clarifying microservice ownership and filtering non-bug customer cases before escalation to development.
QA Engineer I
Mimecast
Lexington
11.2018 - 05.2020
- Tested Java API workflows and backend product behavior for Ataata, Awareness Training, and Engage during integration into Mimecast systems.
- Queried Postgres data and internal reports to d API behavior, investigate customer-impacting issues, and support telemetry-informed product decisions.
- Partnered with support and engineering teams to distinguish product defects from configuration, usage, expectation, or integration issues before escalation.
Engineering Support / Escalation Support Engineer
Mimecast
Lexington
02.2016 - 11.2018
- Deflected 80%+ of escalated cases from engineering teams by triaging reports, identifying non-code issues, and preserving developer focus for product and feature work.
- Owned investigation and root-cause analysis for complex backend and integration issues, coordinating with engineering teams when confirmed defects required code changes.
- Built deep knowledge of microservice interactions, stack ownership, customer environments, and enterprise administration patterns later applied to QA and backend software engineering roles.
Implementation & ExCore Engineer
Mimecast
Lexington
04.2013 - 02.2016
- Onboarded new customers onto the Mimecast email gateway, guiding Exchange/365 configuration, DNS record changes, and migrations from existing email/security services.
