Production Engineering Case Study

Healthcare / Backend / Full-Stack Engineering

Healthcare Scheduling Platform

Production engineering work across healthcare scheduling workflows, backend APIs, authentication flows, mobile fixes, and reliability improvements.

Problem

Healthcare teams rely on reliable scheduling and coverage workflows. Issues in authentication, calendar behavior, backend logic, or mobile flows can create friction for users and internal teams.

Solution

Worked across backend APIs, frontend/mobile flows, authentication, calendar behavior, and reliability improvements to support more stable healthcare scheduling workflows.

Result / Learning

Contributed to production systems used for healthcare scheduling and operational management, improving maintainability, reliability, and user experience across key workflows.

AI Integration Case Study

AI / Internal Tools / Workflow Automation

AI Workflow System

An AI-powered workflow system for document search, structured answers, and internal knowledge automation using modern LLM APIs.

Problem

Teams often store important information across PDFs, documents, spreadsheets, chats, and internal tools. Finding the right answer can take time and create repetitive manual work.

Solution

Designed an AI workflow system that can ingest documents, index content, retrieve relevant context, and generate structured answers using modern LLM APIs.

Result / Learning

Created a reusable AI workflow architecture that can be adapted for internal search, support automation, operations, and knowledge management use cases.

Product Engineering Case Study

Supply Chain / Blockchain / SaaS

BlockTrack Technical Case Study

How LayerSeven designed a blockchain-powered supply chain traceability platform.

Problem

Agricultural and logistics supply chains can suffer from poor visibility, manual tracking, middlemen dependency, and limited trust between stakeholders.

Solution

Designed a full-stack traceability platform where supply chain actors can create, transfer, and verify product batches through structured workflows and blockchain-backed verification.

Result / Learning

Built a working product prototype demonstrating end-to-end supply chain traceability, role-based workflows, batch tracking, shipment management, and blockchain-backed verification.
