Experienced leadership. Reliable systems. Fortune 100 scale.

Adam LaCasse

Senior Full-Stack Engineer | Enterprise Platforms & Applied AI

I take messy business problems and turn them into durable systems that real people rely on. I’m looking for user-centric engineering leadership work where I can shape architecture, lead end-to-end delivery, and apply AI where it creates real leverage.

Positioning

Experienced business fluency and platform delivery

Senior engineering ownership, enterprise-scale systems, and prior business leadership. That makes this résumé less about tool exposure and more about turning messy operational domains into software people can trust.

Enterprise modernization lead

Shape architecture and implementation plans across service boundaries, AWS services, platform data contracts, rollout sequencing, and support ownership.

Product-minded engineer

Own discovery, build, rollout, and iteration with HR business partners, recruiters, analysts, and executive sponsors.

Business operator turned builder

Nearly two decades leading finance and operations teams before engineering, including law-firm administration and FP&A leadership.

Applied AI with substance

M.S. Computer Science work in AI foundations, deep learning, and AI ethics, plus hands-on LLM integration and retrieval patterns.

Core capabilities

Every day tools

Languages & Frameworks

Backend, Data & Cloud

PostgreSQL, MySQL, REST/GraphQL APIs, microservices, AWS, CI/CD, containerization, observability

Applied AI

LLM integration, prompt design, retrieval patterns, AI-assisted developer tooling. Recent MSCS coursework in foundations of AI, deep learning, and AI ethics

Labors of love

Personal projects that show the same instincts

The production work is enterprise and private. The public work shows the same bias toward explicit domain models, low-noise workflows, and systems that stay understandable as they grow.

Experience

Liberty Mutual Insurance - Senior Software Engineer

Portsmouth, NH (Hybrid)

2019 - Present
  • RMIS platform redesign (2025-Present): Lead engineer on the data layer of a multi-year, ~$4M modernization of a risk management platform supporting ~$4B in annual premium and ~70K users (enterprises, brokers, auditors, internal teams) - replacing legacy mainframe workflows with cloud-native services on AWS, currently in the foundations phase building toward incremental cutover.
  • Defined shared data contracts and migration patterns (dual-write, shadow read, expand-contract) across downstream consumers spanning reporting pipelines and customer-facing data flows - new services can stand up behind the live legacy app without disruption.
  • Established service boundaries, rollout sequencing, and reference patterns the broader program builds against - downstream teams can move on the new architecture independently rather than waiting on a full ecosystem cutover.
  • People & Talent platforms (2019-2025): Engineered several internal greenfield platforms from initial discovery through rollout - performance management, a people knowledge hub, compensation support, and more - consolidating a sprawl of third-party tools and spreadsheets in support of Liberty's "best place to work" strategic priority across ~40K multilingual employees. Promoted from Software Engineer to Senior in 2021 mid-arc, through ownership of complex features and steady delivery on ambiguous technical problems.
  • Ran discovery, design, and rollout for each product in direct partnership with HR business partners, recruiters, analysts, and exec sponsors - turning loosely defined people-operations problems into systems each function actually adopted.
  • Operating principles across both programs: boring tools, explicit boundaries, small reversible shipments - applied through engineer mentorship and design/review standards adjacent teams now follow.
  • Brief rotation with the data and analytics engineering team - databases, warehousing, and BI pipeline work.
Tech: TypeScript, JavaScript, Node.js, React, Java (Spring), Python, PostgreSQL, AWS

Trilogy Education - Teaching Assistant

Portsmouth, NH

2019
  • Guided students through full-stack MERN development, debugging, and the habits that separate working code from maintainable code.
  • Sharpened the mentorship and technical-communication muscles I still use in engineering leadership contexts today.

The ATOM Group - JavaScript / Web Engineer (Contract)

2018 - 2019
  • Shipped performance, UX, and developer-experience improvements across client web platforms.
  • Implemented end-to-end testing that surfaced production defects and performance bottlenecks before customers did.

Devine Millimet - Director of Administration

Prior leadership experience (pre-engineering)

2015 - 2018
  • Directed operations - IT, finance, HR, marketing, and facilities - for one of New Hampshire's largest law firms.
  • Delivered measurable operational efficiencies through process analysis, systems thinking, and steady cross-functional leadership.

Brown Rudnick - Director of Financial Planning & Analysis

Prior leadership experience (pre-engineering)

2005 - 2015
  • Progressed from analyst → manager → director, including through the 2008 financial crisis and the years of operational discipline that followed.
  • Achieved >15% profitability improvement through strategic financial modeling, operational analysis, and executive partnership.

Education

  • M.S. Computer Science - Artificial Intelligence Concentration - Merrimack College
    Expected 2026

    Coursework: foundations of AI, deep learning, AI ethics, data modeling, and system design. The concentration is substance, not decoration - how modern AI actually works and where it earns its keep.

  • Full-Stack Web Development Bootcamp - University of New Hampshire
    2018
  • B.A. Management - Curry College
  • Additional study: Jazz Composition - Berklee College of Music

Leadership & Impact Themes

  • End-to-end product engineering: discovery, ship, iterate
  • Cross-functional collaboration with non-technical stakeholders (HR, recruiting, operations, executives)
  • People & Talent domain depth (performance, knowledge, recognition, recruiting)
  • Applied AI: LLM integration, prompt design, retrieval patterns
  • Boring-tech bias, explicit boundaries, small reversible shipments
  • Mentorship and standards-setting without over-engineering
