I ship production systems, then teach the fundamentals behind them
About Me
Hello! I’m Francisco Calveyra, a Software Engineer and Computer Engineering student at Universidad Austral.
I work primarily across backend engineering, AI-powered systems, and product development, with experience building production software, RAG pipelines, cloud services, and cross-platform applications. I tend to gravitate toward backend and AI work, but I’m comfortable working across the stack and owning features end to end.
Alongside my professional work, I’m a Teaching Assistant in Programming, Software Engineering, and System Design. Teaching has become an important part of how I strengthen my own fundamentals and approach software with a stronger focus on clarity, maintainability, and good design.

Claude Desktop Swap
An open-source Go CLI that switches between multiple Claude Desktop accounts without logging out, treating the app's local SQLite cookie database as the authoritative session state. Features atomic profile snapshot/restore with WAL checkpointing, rollback on failed writes, and strict file permissions, shipped as versioned cross-platform binaries via GoReleaser.
Polyglot
An open-source AI skill library that lets agents translate files between formats by discovering or building the required converter at runtime, instead of relying on hardcoded conversions. Built on a LangGraph agentic backend orchestrating skill discovery, conversion and format validation, with Azure infrastructure fully provisioned through Terraform and a test harness spanning unit, integration and security scanning.
Agentic DevTools
A terminal-based AI assistant for Python code quality. Paste code and ask it to lint, format, refactor, or run tests — the agent picks the right tool, executes it, and explains the results. Features RAG-powered refactoring with GitHub repo indexing.
Rusty Instagram Bot
A Rust backend integrating with Meta's Instagram Graph API for DM auto-replies, webhook forwarding, and story uploads. Features HMAC-SHA256 signature verification and a Terraform-provisioned Azure cloud environment.
Experience
Game Developer
Develop cross-platform educational games with Flutter and the Flame engine, integrating interactive Rive animations and Firestore-backed state management to track user progress. Partner with multidisciplinary design and education teams to turn visual concepts into working gameplay features.
Full-Stack Developer
Built the backend (Firebase Cloud Functions, Firestore, Auth) and the base Flutter client for an on-demand roadside-assistance app, plus a management dashboard for admins and fleet owners shaped by interviews with real operators. Re-engaged as a paid freelancer to build Cloud Functions for a WhatsApp bot and a web assistance-tracking page that replaced the original Flutter driver flow.
AI Software Engineer
Engineered a real-time AI interview suite for HR teams, wiring OpenAI's Realtime API into live voice interview agents alongside Python agents for meeting synthesis and candidate evaluation. Built high-precision RAG pipelines on MongoDB vector search for semantic resume matching, and led the macOS migration with ScreenCaptureKit, PyObjC and PyAudio.
Flutter Trainee
Built and shipped production UI components and features for Disney Parks in Flutter and Dart under senior engineer mentorship. Worked inside an Agile squad, taking part in sprint planning and peer code reviews that lifted code quality and cut review turnaround.
