Marc Pios — Financial Systems Developer
A background in management accounting, forensic accounting, and financial consulting — applied to building the accounting systems, automation pipelines, and smart contracts that make financial operations reliable, automated, and transparent.
Marc is a financial systems developer with a background in management accounting and a drive to build the tools that make financial operations more reliable, automated, and transparent. His work spans cloud accounting systems, workflow automation, AI agents, and on-chain financial infrastructure.
Trained in management accounting, certified in forensic accounting and financial consulting, and writing smart contracts since 2021 — the same discipline that keeps a ledger balanced now shapes how the code is designed, tested, and audited.
Double‑entry discipline applied to code: every state change should balance, and every rule should be testable.
Systems should explain themselves — events, logs, and records that survive scrutiny long after the transaction.
Assume adversarial inputs. Identify who can call what, with which funds, before the logic is written.
Small, well‑defined modules that integrate cleanly with the platforms finance teams already run.
Four concurrent lines of work — automation for finance teams, web applications, on‑chain systems, and management accounting — each entry posted with its period and the work delivered.
Certified Forensic Accountant (CrFA) credential, covering forensic accounting principles, investigative techniques, and legal aspects of financial fraud examination.
Certified Financial Consultant (CFC) credential, covering financial planning, investment strategies, and ethical practices in the financial industry.
Combining accounting principles with systems thinking, laying the groundwork for a career at the intersection of finance and technology.
From chart-of-accounts setup to smart-contract deployment: the modules that make up a working financial system.
Directing AI coding and operations agents across development and automation—pair-programming in Cursor, reasoning with ChatGPT, Claude, and Gemini, and running self-hosted OpenClaw and Hermes Agent setups for persistent, tool-using work.
Designing and implementing custom n8n workflows to automate data pipelines, API integrations, and repetitive tasks across financial systems.
Proficient across multiple accounting platforms from setup and chart of accounts configuration to reconciliation workflows and financial reporting
Developing robust, server-rendered financial web applications, clean architecture, type-safe APIs, and interfaces built for data density and reliability.
Implementing performant, scroll-driven animations and UI transitions using GSAP and Motion, with Lenis for buttery-smooth scroll experiences.
Developing smart contract systems that encode financial rules on-chain, with emphasis on security, auditability, and upgradeability patterns.
Proficient with modern productivity and collaboration suites for documentation, project tracking, and cross-team communication in professional environments.
Production systems with live links — automation libraries and web applications built on the same stack described above.
A persistent Node.js service that holds a Discord Gateway connection, normalizes new and edited messages into a stable JSON envelope, and delivers them to an n8n webhook with retries, idempotency, and bounded concurrency.
