Shipped platforms
BrasMedia, FinFriend, and Gestão & Transporte cover branch operations, financial utility, and operational control.
Arthur Hoch · Porto Alegre, Brazil
I build developer tools, workflow systems, and software for real operations.
From branch-screen platforms and financial calculators to browser tools and operational systems, I ship products built around recurring work.
Developer tools
Cookie Injector and URL Swap reduce repeated browser and environment friction.
Technical continuity
Public GitHub work and the DES/OpenMP/OpenMPI project show longer-term technical depth.
Selected work
Products and tools with real use behind them.
The strongest pattern here is practical execution: software for branch operations, financial estimates, developer workflows, and operational clarity.
Featured products
Platforms with heavier product scope.
BrasMedia, FinFriend, and Gestão & Transporte are the clearest proof of range across operational platforms, calculator products, and business workflows.
Operational Platform
BrasMedia
Corporate TV software for branch operations and centralized screen management.
Built for multi-location teams that need reliable screen control, urgent updates, layout governance, and stable playback across many branches.
- Problem
- Branch screens are hard to govern when content, layout updates, and operational visibility depend on local manual handling.
- Why it matters
- It shows execution in a serious B2B workflow where rollout, governance, and operational continuity matter.
- What it demonstrates
- Multi-location operational thinking
- Centralized workflow design
- Product framing for real teams
- Proof
- Public product site
- Clear branch-operations positioning
- Arthur Hoch is referenced publicly on the site
Financial Product
FinFriend
Financial calculator platform for mortgage, loan, retirement, tax, and budgeting estimates.
It organizes dozens of focused calculators into one useful product for people who need fast estimates before reaching for heavier financial software.
- Problem
- Many financial questions start with estimation, but the tools people find are often fragmented, slow, or too narrow.
- Why it matters
- It shows practical product breadth, information architecture, and clear user-facing utility.
- What it demonstrates
- Utility-first product thinking
- Scalable calculator architecture
- Clear decision-support flows
- Proof
- Public platform with over 46 calculators
- Coverage across mortgage, loan, retirement, tax, and budgeting topics
- Public about page emphasizes simple, accessible tools
Business Software
Gestão & Transporte
Operational software for logistics, reporting, and financial control.
Built for day-to-day transport operations where reporting, cost visibility, and ongoing control matter.
- Problem
- Transport teams need clearer visibility into costs, reporting, and daily operational status.
- Why it matters
- It shows execution in a real business domain where software has to support practical decisions, not just look polished.
- What it demonstrates
- Operational software delivery
- Business-to-product translation
- Workflow support in a serious domain
- Proof
- Public product site
- Visible logistics and financial-control framing
- Monitoring and reporting positioning
Developer tools
Focused tools for daily technical work.
Cookie Injector and URL Swap are smaller in scope, but they are strong proof of workflow sensitivity, product judgment, and public shipping discipline.
Developer Tool
Cookie Injector
Browser extension for faster cookie work in active tabs.
It turns a repetitive testing task into a cleaner flow with saved values and direct injection.
- Problem
- Session setup and cookie testing are slow when handled by hand.
- Why it matters
- Public distribution and clear usability choices make it stronger than a portfolio-only utility.
- What it demonstrates
- Developer empathy
- Public shipping discipline
- Usability-aware implementation
- Proof
- Chrome Web Store listing
- Visible public usage signal
- Accessibility and keyboard support
Developer Tool
URL Swap (Dev Helper)
Small browser tool for switching environments and redirecting URLs during development.
Built around a narrow pain point: repeated URL changes across localhost, staging, and production-like environments.
- Problem
- Environment switching wastes time when the same redirects happen all day.
- Why it matters
- Small scope, but strong proof that product judgment also shows up in narrow developer tooling.
- What it demonstrates
- Workflow sensitivity
- Lean product scope
- Fast client-side utility
- Proof
- Chrome Web Store listing
- Clear environment-switching use case
- Built for repeated technical use
Earlier technical work
DES Cipher with OpenMP and OpenMPI
Not a flagship product. Clear continuity proof.
Academic Technical Project
University-era C project built around DES, parallelism, and lower-level implementation.
It matters here as historical depth: hands-on work with C, OpenMP, OpenMPI, and performance-oriented thinking well before the later browser tools and business software.
- Technical focus
- C, with supporting C++ and Makefile
- Parallelism with OpenMP and OpenMPI
- Systems-oriented and performance-minded implementation
- Why it belongs here
- It shows that the technical side of the portfolio did not start recently. There was already serious implementation work during university.
- Public grounding
- Public GitHub repository
- Repository description: "Des with openmp and open mpi"
- Mostly C, with C++ and Makefile in the language mix
About
One execution pattern, different product contexts.
This portfolio makes more sense as a pattern than as a random collection: understand recurring work, scope the software carefully, and ship something people can actually use.
BrasMedia handles branch-screen operations. FinFriend turns financial estimation into a usable calculator platform. Cookie Injector, URL Swap, and Gestão & Transporte add depth across technical and operational workflows.
The DES/OpenMP/OpenMPI project shows the technical side started earlier. The through line is still the same: practical software, clear use, and real execution.
What I build
- Developer tools for repeated technical workflows.
- Workflow systems and operational software for branch, logistics, and control-heavy environments.
- Practical digital products such as calculator platforms and decision-support tools.
Grounding
- Based in Porto Alegre, Brazil.
- Professional experience includes ADP.
- University background at Universidade de Santa Cruz do Sul.
How I work
- Start from the workflow, not the feature list.
- Keep scope disciplined and interfaces readable.
- Prefer shipped proof over inflated positioning.
Proof
Public signals that hold up.
Shipped products, public links, and older technical work make the case more clearly than louder language.
Operational platforms
BrasMedia and Gestão & Transporte show work in branch operations, logistics, reporting, and control-heavy environments.
Financial product utility
FinFriend turns mortgage, loan, retirement, tax, and budgeting estimates into a broader calculator product with over 46 public tools.
Developer tools
Cookie Injector and URL Swap are public tools built around repeated technical workflows.
Public profile hub
GitHub shows the build history. Linktree gives one lightweight hub for profiles, shipped products, and public entry points.
Technical continuity
The DES/OpenMP/OpenMPI repo adds older systems-oriented depth: C, parallelism, and performance-minded implementation.
