I turn ambiguous requirements into clear product decisions and reliable software. I take ownership from discovery through delivery, across frontend, backend, and AI.

Personal finance fintech
Full Stack Developer / AI Engineer
Built and evolved a connected finance product across accounts, transactions, transfers, recurring activity, shared finances, currencies, insights, and AI-assisted interactions on web and mobile.
Took ownership from product design and domain modeling through security, performance, observability, and release preparation, keeping financial rules coherent as the product expanded.
Refactored the patient app and connected monitoring plans, medical devices, measurements, thresholds, alerts, triage, follow-up, video consultations, and clinical administration.
Reworked state and data boundaries, helped consolidate fragmented services, and became a technical reference across mobile, web, and backend. AI-assisted decisions stayed under clinical review.
Modernized a production platform across three markets, owning station maps, prices, offers, rewards, premium, payments, cards, security, localization, and critical releases.
Resolved a critical stations-map issue two weeks before launch. Worked across Fleetcor/Pay+ integrations, transactional correctness, performance, crashes, and release regressions.
Delivered four client products from discovery and architecture through release: cross-platform commerce, a professional-services marketplace, an interactive football tactical board, and crypto-finance systems.
Adapted between different users and business rules, covering catalogue and affiliate flows, service lifecycles, payments, responsive drag-and-drop tools, financial calculations, dashboards, and role-based access.
Built a modular product for newspaper kiosks covering inventory, POS, cash, suppliers, customers, deliveries, route planning, and returns.
Developed the Firestore model and integrated authentication, validated forms, shared state, maps, directions, and cloud hosting. Repeated architectural refactors turned a learning project into a sustained operational product.

Contractor and supplier compliance SaaS
Full Stack Developer
Built and maintained production functionality used by Telecom, Pluspetrol, and Tenaris. Worked across frontend, backend, business-critical MySQL data, deployment, and technical support.
Handled debugging, QA, AWS releases, and structural codebase fixes while preserving established compliance workflows and production continuity.
A native macOS widget that brings Apple Music, Spotify, and YouTube Music into one desktop interface, with artwork, playback controls, and a background host.
A personal tool that turns structured work history into tailored CVs. It selects relevant experience, drafts focused sections with AI, and saves the result to Notion.
A small React hook for asynchronous requests. It gives loading, error, and result states a reusable interface, with custom response extraction and guards against updates after cleanup.
An unofficial macOS wrapper for Graveyard Keeper 2. It sets up Wine and Apple’s graphics translation layer, imports an owned Steam copy, and creates a desktop launcher.
A browser-based finance demo with separate intake, planning, auditing, and publishing steps. Deterministic functions exchange visible JSON handoffs and run a reproducible correction loop.
A command-line checker that finds missing YAML translation keys and incomplete counted-value translations, then returns a failing exit code when coverage is incomplete.
An AI review experiment that scans React and React Native pull requests for nested component patterns and drafts contextual feedback using AST analysis and OpenAI.
