Product engineer. I ship the whole thing.
Frontend, backend, database, infrastructure — and the product decisions in between. I've built and operated production SaaS across esports, fintech, and regulated consumer products, working AI-native with Claude Code at team-scale output.
Work
Real products, in production, built end-to-end. Architecture notes included — ask me about any of it.
Seedro
Founder & Product Engineer — esports coaching & team management SaaS
An esports coaching and team management platform, built solo, end-to-end: Flutter/Dart frontend, Flask REST backend, PostgreSQL database.
The product is architected as a multi-role platform — coaches, players, and recruiters — with a three-tier access model, game-specific theming across six titles, and a full curriculum and season-management system. I took it from stakeholder spec to shipped frontend: translating a ten-feature-area product document into a structured engineering spec, establishing the design system and brand asset pipeline, and delivering the build against it, coordinating with a distributed team across engineering, business analysis, and design.
Production database migration: Supabase → DigitalOcean
Seedro infrastructure
Migrating a live product off a managed backend is where "full-stack" gets tested. I planned and executed Seedro's move from Supabase to DigitalOcean managed Postgres:
- Audited the full Row-Level Security surface and rewrote 51 RLS policies, replacing
auth.uid()dependencies with session-variable patterns (current_setting) so the database no longer assumed Supabase's auth layer. - Replaced Supabase Auth with a custom Flask authentication service (JWT), keeping the Flutter client contract stable.
- Schema dump, migration sequencing, and rollback planning for a production dataset.
The point of this case study: I don't just build on managed platforms — I can take ownership of the layer underneath when the product outgrows them.
Consumer intelligence platform
Product & Tokenomics Engineer — US fintech
Behavioral-intelligence fintech with a registered security token. I authored the token litepaper — rewriting governance language for regulatory accuracy in a registered-security context — and designed the SAFT pre-sale structure, staking tiers, data-quality scoring mechanics, and emission schedule.
This is the product-judgment side of my work: documents that had to satisfy engineers, investors, and compliance simultaneously.
Momoñus & regulated consumer products
Co-Founder
A regenerative agtech and consumer lifestyle brand (co-founder, 4+ years). I designed its WhatsApp-commerce architecture and website plan, and built the digital design system from the brand identity.
On the regulatory side, I led federal compliance analysis for a US-licensed processing operation under P.L. 119-37, identifying product reformulation requirements ahead of the November 2026 deadline — experience navigating a regulated industry where engineering and compliance constraints collide.

How I work
AI-native, judgment-first
I treat AI coding agents as leverage, not a substitute for engineering judgment. I own architecture and data-model decisions, decompose work into verifiable specs, direct Claude Code against them, and review, test, and edit every change before it ships. The result is solo delivery of full-stack systems — apps, auth services, database migrations — at team scale, with an auditable trail of specs and design docs.
Builder mindset
I'm comfortable owning a feature from idea → UI → backend → infra → deployment. Fewer handoffs, faster iteration, no "works on my machine" surprises.
Operational discipline
Clean deployments and strong defaults: firewall rules, TLS, sensible access, secrets management, and documentation so your team can maintain what we build.
Engagements
I'm open to three shapes of work:
- Full-time remote — product engineer / founding engineer roles where I own features end-to-end.
- Contract & contract-to-hire — scoped builds, migrations, or "we need this shipped" projects. Contract-to-hire welcome: evaluate me on real work.
- Fractional — ongoing part-time engineering ownership for early-stage teams.
Based in Panama City, Panama — full US business-hours overlap. Experienced international contractor.
