Selected work with product weight.

A few representative builds across founder tools, operational systems, and data-heavy interfaces.

Atlas Studio project visual

AI workspace

01

Atlas Studio

A collaborative canvas for founders to plan product work with agent-assisted research, scoped briefs, and engineering handoff artifacts.

Turned scattered discovery into a shippable workflow teams could reuse each week.

Next.jsRSCPostgresLLM tools
Northline Ops project visual

Internal platform

02

Northline Ops

A planning surface for a logistics team, combining permissions, audit history, exception handling, and fast operational search.

Reduced handoffs between support, operations, and engineering without adding another spreadsheet.

ReactNodeQueuesRBAC
Signal Ledger project visual

Data product

03

Signal Ledger

A decision log for technical leaders that connects product bets, customer evidence, architecture notes, and delivery status.

Helped a small team keep strategy, execution, and technical tradeoffs in the same room.

Tools chosen for durable speed.

I like modern stacks, but I care more about clear boundaries, predictable releases, and systems a team can understand.

CITestingObservabilityReviewsDocs

Fast first impressions

Server-rendered pages, stable layout, careful image loading, and interaction code kept out of the critical path.

Readable architecture

Small modules, clear boundaries, typed contracts, and boring infrastructure where boring is the correct choice.

Tasteful product detail

Interface states, copy, spacing, empty paths, and edge cases get designed as part of the work, not after it.

AI that earns its place

Agents and copilots are scoped around real workflows, with guardrails, visible state, and useful fallback behavior.

A working process for uncertain product bets.

/ Operating loop

The work stays tight: frame the job, prototype the path, build the core, then refine after real contact.

04Tighten after contactReady

Frame the job

Clarify the audience, the proof needed, the failure modes, and the smallest version worth shipping.

Prototype the path

Make the workflow tangible early, then use the prototype to expose unclear requirements and hidden costs.

Build the durable core

Turn the chosen path into maintainable components, data models, tests, and release habits.

Tighten after contact

Watch how real people use it, refine the rough edges, and leave the team with clear operating notes.

Alex brings rare range: product taste, implementation speed, and the judgment to keep a system maintainable.

Mira Patel, founder and product lead

Led interface rebuilds without pausing product delivery.
Partnered with founders from product sketch through launch.
Built internal systems where speed, permissions, and audit trails mattered.
Comfortable moving between Figma, database schema, API design, and production debugging.

Selected notes from the work.

Short writing on product engineering, interface judgment, and the parts of AI UX that need more care.

AI UX

Designing agent states that people can trust

Why the most important interface for an AI feature is often the state between asking and answering.

Read note
Engineering

The case for smaller full-stack teams

A practical note on how tight product loops change architecture choices, review habits, and delivery speed.

Read note
Craft

Portfolio pages should behave like product pages

Recruiters and founders need evidence, not atmosphere. The page should help them make a serious decision.

Read note

Available for focused product builds.

Best fit: small teams that need senior product engineering, a sharper interface, or an AI workflow that should feel real.

Current focus

AI-assisted product surfaces, internal systems, and fast launch paths for founder-led teams.

Engagements

Product build sprints, frontend system upgrades, technical prototypes, and architecture reviews.
