Software Engineer — Bentonville, AR

Romeo Adjam

I'm the engineer who can't stop building. I spend my workdays at Walton Personal Philanthropy Group, shipping data products at enterprise scale. I spend my off-hours in the workshop — turning real business problems into working software. Seven-plus years across Python, C#, Node.js, and SQL: APIs, data pipelines, AI automation, and full-stack apps. My current build is Revoloyalty, a rewards-card platform that helps short-term rental hosts turn check-ins into long-term loyalty.

Case Studies

01

Real-Time Data Integration Platform

At Leggett & Platt, the warranty call center team relied on manual exports and stale batch reports. 400+ database tables contained redundant, inconsistent data — and business partners had no programmatic access to ticket information.

SQL Server C# / .NET REST APIs Stored Procedures WPF

What I Built

  • Stored procedures to clean and normalize data across 400 tables, running 2,000+ queries to fix integrity issues
  • RESTful API exposing customer service ticket data to partners in real time — replacing batch exports with 24/7 live access
  • Database triggers to automate data capture and retrieval, removing manual intervention
  • In-house Windows app in C# for processing returned electronic components

Impact

Partners went from waiting days for batch reports to accessing live data around the clock. Data cleanup reduced query errors across 400 tables and established a reliable foundation the team continues to build on.

02

AI Automation Workflow Library

As LLMs and vector databases matured, there was no curated, ready-to-use collection of n8n automation workflows combining traditional automation with modern AI stacks — developers had to wire up each integration from scratch.

n8n Python OpenAI API Pinecone Weaviate Supabase Redis

What I Built

  • 200+ plug-and-play n8n workflow templates spanning AI, DevOps, finance, and IoT
  • Full RAG stack integration: Pinecone, Weaviate, Supabase Vector, Redis for storage; OpenAI, Cohere, Hugging Face for embeddings; GPT-4 and Claude 3 for LLM chat
  • Each workflow ships with docs, error handling, guard rails, and Slack/Google Sheets alerting
  • Organized into 20+ categories with master README and per-category documentation

Impact

Open-source resource enabling developers to import a JSON file, add credentials, and activate production-grade AI workflows in minutes instead of days.

Revoloyalty — Loyalty Rewards Platform

Short-term rental hosts compete on listings, photos, and price — but rarely on relationships. Most have no way to turn a one-time guest into a returning one, and existing loyalty tools are built for retail, not hospitality.

Python FastAPI PostgreSQL React REST APIs Cloud Infra

What I Built

  • Full-stack rewards-card platform purpose-built for short-term rental hosts (Airbnb, Vrbo, direct bookings)
  • Backend architecture for issuing digital rewards cards, tracking stays, and redeeming guest perks
  • Guest engagement flows that turn check-ins into long-term relationships — birthday perks, returning-guest discounts, referral rewards
  • Solo technical founder handling product strategy, architecture, and go-to-market

Impact

An early-stage platform giving STR hosts a real way to build guest loyalty — not just chase 5-star reviews.
