Intro

Jagger Brulato

Senior full-stack engineer across product, systems, platform, and infrastructure work.

I’m a senior engineer who works across product, backend, platform, data, infrastructure, and developer tooling. I like roles where those pieces connect.

I’ve worked at Google, startups, platform teams, and product teams.
I can lead the work, make technical decisions, write the code, mentor engineers, and keep the system understandable as it grows.
My side projects follow the same pattern: languages, runtimes, compilers, simulations, games, compression, renderers, and backend utilities.

Focus

I like work that crosses product, backend, data, infrastructure, and developer tooling.

For me that has meant consumer apps, React and Three.js product surfaces, Node services, platform automation, data pipelines, mobile software, dashboards, and internal systems.

Work across the stack

I can work from the user experience through the backend, data model, event flow, infrastructure, and runtime behavior.

Use systems work in product work

Platform and data systems work has made me better at product engineering. I think carefully about boundaries, data flow, queues, observability, failure modes, and rollout paths.

Build things other engineers use

I like building tools, dashboards, APIs, deployment paths, Terraform workflows, CI/CD systems, and abstractions that other engineers use.

Experience

My experience spans product, platform, data, mobile, infrastructure, and leadership.

That includes senior startup work, Google data systems, AWS platform engineering, internal developer platforms, production apps, and team leadership.

Senior software engineering role at a clean-energy startup, focused on the Palmetto app and the backend services behind its home-energy product experience.

Building Node/Express services, MongoDB integrations, React product surfaces, and testable flows that help the Palmetto app turn complex home-energy data into a clearer customer experience.
Delivering customer-facing marketplace, rewards, recommendations, referrals, and onboarding features for homeowners moving through solar and energy workflows.
Contributing to solar production, electricity usage, grid export, utility connection, and energy-trend analytics for the newer Solar and Electricity usage experience.
Improving OAuth/JWT/Auth0-backed utility authentication, account state, energy history, and statistics flows across iOS, Android, and web clients.

Reference

How I work

I care about clear systems, practical architecture, and maintainable code.

I like code with clear boundaries, obvious ownership, useful tests, good observability, and tradeoffs the team can explain.

Working with a team

I’m useful when a team needs technical direction, implementation, code review, architecture decisions, and help unblocking other engineers.

Technical leadershipDeveloper onboardingCross-functional communicationSystem designExecution under ambiguity

Systems and platform work

A lot of my strongest work is around platforms, reliability, observability, CI/CD, deployment paths, cloud infrastructure, and asynchronous systems.

Leadership

I lead by making the work clear and staying involved in the implementation.

I set direction, make tradeoffs, mentor engineers, organize execution, review code, and take implementation work myself.

Set a clear direction

Turn an ambiguous goal into a plan with clear priorities, ownership, milestones, technical decisions, and a path to delivery.

Lead from the work

Make architecture decisions with firsthand context, and take on difficult implementation work when the team needs it: APIs, data flow, platform code, UI state, or deployment logic.

Organize for momentum

Break work into parallel tracks, surface dependencies early, and keep communication direct across product, design, engineering, and operations.

Raise the whole team

Share context, review thoughtfully, and help engineers take ownership of larger parts of the system, from feature work to architecture and production support.

Contact

If you need a senior engineer who can lead and build, reach out.

Email is the most direct way to reach me. I’m interested in startups, product engineering, platform work, data-heavy systems, infrastructure-heavy teams, and senior roles where I still write code.
