Shailen Sheth
Finance Engineer
I build modern finance systems for high-growth companies — combining accounting, automation, controls and AI-enabled workflows.
Impact
Building the operating system behind modern finance teams
Systems, workflows and infrastructure designed to make finance faster, more reliable and easier to scale.
AI
Agentic finance
AI Workflows
Embedded AI agents and LLM tooling into repetitive finance processes — automating low-value work and freeing capacity for higher-judgement tasks.
Multi
Connected stack
System Integrations
Connected finance systems across ERP, HR, payroll, PSP and reporting platforms — reducing manual handoffs and improving data consistency.
Flow
Clean inputs
Data Flows
Built and managed finance-owned data flows across ERP, PSP, HR and reporting systems — focusing on clean inputs, clear mappings and reliable outputs.
Logic
Structured checks
Reconciliation Logic
Built structured checks across PSP, backend and finance data to identify breaks faster and give Engineering/Data clearer evidence when issues surfaced.

Finance Builder Mode
Turning messy finance problems into systems that hold up.
I approach finance like a builder: map the mess, simplify the flow, automate what should not be manual, and leave behind controls and documentation that make the process easier to own.
MapMessy current-state processes.
DesignThe clean processes.
BuildWorkflows, docs, controls and automations.
RunUntil it survives real pressure.
