Kajun Project:

• Built and integrated currency-rate-service (Spring Boot 3) using MySQL, Flyway, Redis, JWT, and OpenAPI, exposing endpoints for historical FX normalization consumed by PNL/Reports/Time Sheets.

• Drove the Spring Boot 3 / Spring Security 6 migration across Auth, Access, and Country-Calendar by replacing legacy configs with SecurityFilterChain/authorizeHttpRequests and refactoring to constructor injection.

• Set up infra & CI/CD by Dockerizing services, standardizing MySQL/Redis + Flyway configs, and adding GitLab CI pipelines for build, test, and image publishing.

• Engineered scalable backend systems for an AI-based learning app using Node.js, Express, and MongoDB Atlas, supporting 100+ users.

• Built RESTful APIs for real-time TTS/STT pipelines with OpenAI and Deepgram, reducing audio processing latency by ~40%.

• Developed RAG workflows with note chunking, vector embeddings, and semantic search using Pinecone.

• Integrated LLMs via LangChain for flashcard generation, dynamic quizzes, and AI tutoring, powering 500+ study interactions.

• Designed flashcard feedback logic and personalized learning reports, increasing user engagement during testing by 30%.

• Managed AWS S3 storage for 1,000+ user-uploaded files and collaborated with React Native engineers on full-stack features.

• Extracted truck driver records from the company system, dispatched certificates of insurance, performed data entry for insurance quotes, communicated with 20–25 clients, and finalized policies.

• Performed quality checks on endorsements (unit additions/deletions) and maintained data using Excel.

• Collaborated with producers to generate sales pitch documents using AMS360.

• Created production and TAT reports in Excel using data from AMS360.

• Partnered with a finance company to retrieve a pre-default loan list, helping reduce cancellations and late fee penalties by 65%.

• Proposed data-driven prototype to boost Sutter Health’s Scout app retention 25–30% via predictive engagement and user segmentation.

• Built an AI-powered chatbot prototype using OpenAI GPT-4 (Flask + React), simulating a virtual therapist for personalized support.

• Analyzed quantitative and qualitative data from user behavior and surveys, generating insights that shaped AI-driven marketing automation and community-based outreach strategies, targeting a 15–20% increase in app adoption.

• Spearheaded testing of 300+ server units from Super Micro, diagnosing hardware issues related to memory modules and system BIOS; documented findings in Excel to track recurring issues and analyze trends for long-term improvements.

• Oversaw end-to-end supply chain operations for server systems, managing logistics for clients like Zscaler; maintained shipment records in Excel and used Power BI to create dashboards visualizing timelines and delivery performance, reducing delays by 15%.

• Developed and implemented streamlined workflows for hardware testing and installation, cutting timelines by 20% through process optimization; introduced standard operating guides and used SQL to query large datasets for improved resource allocation.
