Software Engineer · Full-Stack · End-to-End Ownership

Hand me a problem. I'll hand back a working product.

I work like an embedded product team of one: I take a problem from rough idea to a running product — design, build, deploy — with minimal hand-offs in between.

Operating Model

I tend to take a problem end-to-end — design, build, deploy, and the parts no one volunteers for: auth, billing, the deploy pipeline — so it lands as one decision instead of a chain of hand-offs.

I'm comfortable across the stack and across languages, so I can usually reach for the tool a problem wants rather than the one I happen to know. I lean on AI as a multiplier on delivery speed — it's a big part of why the two products below, each with auth, billing, real-time, AI extraction, and its own marketing site, shipped from one pair of hands. I've also led a small team, so I'm comfortable coordinating when a problem is bigger than one person.

Tier One / Two Products, One Builder

:wq— writequit.dev

Tier One / Developer Tool, Shipped Solo

writequit.dev

Freelance developers juggle tasks, time, and invoices across three disconnected tools — and lose the thread.

A full commercial SaaS — task manager, time tracker, invoice generator — in one terminal-native tool with vim keybindings and markdown tasks.
Auth (WorkOS), invoice generation (jsPDF), real-time chat and shared client boards (Convex), password-gated permissioned sharing.
The product design, the opinionated UX, and the marketing voice — not just the code.
SvelteKit 5 · Convex · Tailwind 4 · deployed on Vercel.

writequit task board: markdown tasks, a running timer, and status filters in one terminal-style view — The board freelancers live in: markdown tasks, running timer, status filters. “manage work, not a workspace.”

writequit time-tracking sessions with a live running timer — Time tracking with live running timers — part of the same tool, not a second app. “tasks. time. invoices.”

writequit invoices generated as PDFs — jsPDF invoice generation — billing built into the same tool, not bolted on.

writequit shared client board management with a share URL, password, and a live chat panel — Password-protected client boards with live chat (Convex) — permissioned sharing, real-time.

the public client view of a writequit shared board, unlocked, with live chat — What the client sees: a password-unlocked board with live chat — the sharing surface, from the other side.

REC00:48:21:stop

A complete, billable product — auth to invoice to live client collaboration — shipped end-to-end by one builder.[Felipe: add metric — e.g., paying customers / time-to-first-invoice]

Tier One / Consumer Product, Shipped Solo

pondera.casa

Choose the right house — without getting lost along the way.

Choosing a property means drowning in tabs and gut feeling. pondera turns a pasted listing URL into a structured decision — real scraping and LLM extraction, not a chat box — then curates, compares, and ranks.

Next.js 16 · React 19 · Convex · OpenRouter (gpt-4o-mini)

Paste
pondera.casa
Paste a link; AI extracts price, area, photos and a pros / cons / watch-outs card. No data entry.
Score
pondera.casa
Score each property on a checklist; portfolio stats update as you go.
Compare
pondera.casa
A side-by-side table with best value per criterion highlighted in gold.
Decide
pondera.casa
AI ranks the options and explains each position in plain language. You decide.

Real AI work — scraping, extraction, curation, ranking — wrapped in a polished consumer product and its marketing site, shipped end-to-end.[Felipe: add metric — e.g., listings processed / decisions made]

Tier Two / Internal Product, Shipped Solo

Venture Lab — Niterra Group

A growing venture team ran on a CRM that couldn't carry portfolio reporting, expenses, or contracts. I built a custom automation layer on Affinity CRM, then scaled it into a full internal portal serving multiple business functions — a Portfolio Management module (automated quarterly report ingestion, real-time dashboards, custom reporting) and an Expense & Contract Management solution.

“One internal portal carried reporting, expenses, and contracts across multiple business functions — an automation layer built on Affinity CRM.”

Replaced manual quarterly report handling with automated ingestion and live dashboards.
[Felipe: add metric — hours saved per reporting cycle / # portfolio companies tracked]

Venture Lab · Niterra Group

Niterra Ventures portfolio dashboard — total invested, estimated exit value and average TVPI above a quarterly revenue trend and a recent-movers list — Portfolio dashboard — total invested, estimated exit value and TVPI up top; a quarterly revenue trend, recent movers and a projected exit timeline below.

Portfolio Management

Niterra per-company financial detail with revenue and net-income charts versus plan — Per-company financials — revenue and net income vs plan, liquidity ratios, quarter and YTD variance.

Niterra exit-valuation model showing enterprise value and MOIC across low, mid and high scenarios — Exit modeling — enterprise value and MOIC across low / mid / high scenarios, with a liquidation-preference waterfall and comps.

Niterra deal funnel tracking conversion across the investment pipeline stages — Deal funnel — conversion from intake to investment across the pipeline, with drop and long-term-follow lanes.

Expense & Contract

Niterra expenditure tracking dashboard with spend versus budget broken down by domain — Expenditure tracking — spend vs budget by domain, paid / forecasted split, multi-currency totals.

Niterra forecast-accuracy report comparing forecasted and actual spend per engagement — Forecast accuracy — forecasted vs actual spend per engagement, scored by variance.

Screens from a public demo seeded with fictional data — no real portfolio data shown.

Tier Two / Precision-Ag Platform · Web + Mobile

Flora — Santos Lab

Agronomists needed drone, satellite, and field data fused into something they could read on a map — and capture offline in the field. I built the React/TypeScript platform (Leaflet + Turf.js) and an offline-first React Native field app, and grew from developer into Tech Lead of five.

Flora interactive map fusing drone, satellite and field data with geospatial analysis — Drone, satellite and field data on one interactive map (Leaflet + Turf.js geospatial analysis).

Flora offline-first React Native field-collection app showing a selected farm — Offline-first React Native field app — the same platform, collected where there's no signal.

Flora analytics dashboard with custom charts turning geospatial data into decisions — Analytics dashboards and custom charts turning raw geospatial data into decisions.

Flora filtered map with analysis layers — Filtered map + analysis layers — [Felipe: add scale metric, e.g. farms/hectares monitored].

A web + mobile platform that put multi-source geospatial data in one place — and the case where I went from building to leading the build, developer to Tech Lead of 5.

Tier Two / Systems Behind the Screens

The systems users never see

HomeOptions' real engine was internal. For a call-center sales operation I owned a custom SvelteKit CRM wired into Twilio's call center, an AI-assisted call-handoff tool, and a Go/HTMX compliance & debt-settlement platform — the systems that don't screenshot well but run the business.

“Three internal systems for a call-center operation — CRM, AI call-handoff, and a compliance/debt-settlement platform — owned end-to-end.”

[Felipe: add metric — calls handled / agent handoff time / compliance cases processed]

Public-facing work

HomeOptions public user portal rebuilt on Next.js server-side rendering — HomeOptions portal: rebuilt React SPA → Next.js SSR for performance and SEO. [Felipe: add load-time before/after or SEO lift]

HomeOptions blog and content surface built on server-side rendering — Content/blog on the same SSR foundation — SEO-driven entry points feeding the funnel.

Liftup public portal and ad-campaign landing page — Liftup portals & ad-campaign landing pages — fast, conversion-focused entry points. [Felipe: add conversion metric]

Back Matter / Built for the Love of It

When the work's done, I still build. A sampling of things made for the love of it — small games, starter templates, sprites and code, all mine.

Stupid Spider game title screen, built in Rust with the Bevy engine — Stupid Spider — a game built ground-up in Rust + Bevy: sprites, original music, and code, all mine.

Go + HTMX starter template — shared for other builders.

Sudokouija title screen — pixel-art sun and moon framing the menu, built in LÖVE for Scream Jam 2025 — Sudokouija — a horror sudoku built in LÖVE for Scream Jam 2025: solve the board before the timer runs out. Sprites and code by hand, no generative AI.
