Work Experience
Full-stack Web Developer
Chase Reiner
- Developed an app that can be used to make automated contact with multiple businesses based on keywords. The work involved Google JSON API to search and use AI-based Python scripting to shortlist the relevant forms intelligently.
- Planned, developed, and deployed a scalable solution that handles millions of search requests daily.
- Developed an app with over 2,000 subscribers signing up for early access in the 1st week.
Python Desktop Application Developer
Jaime Danguillecourt
- Developed a desktop app that allows inventory management of jewelry items. Functions added involved adding, deleting, and updating items with 10-15 fields. The app was developed in Python.
- Built the GUI in PyQt5. The app involved replicating a GUI from a Figma-based concept. GUI was developed exactly as per the client's desire, and he was very happy with the results.
- Added various forms of filtering and sorting methods to the app that allowed filtration by categories, designers, status, and dates. The app was also able to sort by price and ID.
- Integrated some special features in the app, including five consecutive backups and scheduled database backups weekly. The app also included drag-and-drop functionality for images.
AI Application Developer
MY-CAMP GmbH
- Developed an algorithm that allows the storage of robot-based bins in a very compact warehouse. The algorithm was implemented in Python.
- Built interdependent algorithms to calculate the ideal path for moving a robot from one place to another while displacing other robots with minimum possible movements.
- Generalized the algorithm to take a grid of any size. The algorithm was developed in a parametric form that allowed the algorithm to be scaled to any grid size or any situation.
- Developed a GUI-based interactive simulator that allows inputting multiple grid sizes in which robot movement occurs. The simulator was developed in PyQt5.
AWS IoT Developer
Online Freelancing Agency
- Developed a remotely operated multi-channel DSLR camera control system with Raspberry Pi installed at the nodes, ESP32 as wireless hardware, and Python desktop app as control panel.
- Built golf training hardware that strikes the balls in front of the golfer based on sensory inputs received by the machine and completed the product's mechanical design and electronic development.
- Programmed a React Native mobile app with Node.js back end, which interfaces with a remote ESP32-based camera while using AWS IoT MQTT broker as a communication pipeline.
- Developed control hardware and algorithms for tracking solar panels.
- Created a series of software-operated toys for a client.
R&D Project Manager
The National University of Sciences and Technology
- Developed and led a project with dynamic small arms targets capable of detecting bullet hits using piezoelectric sensors. A desktop application was designed to control the overall system and monitor firing results.
- Built control and monitoring system for 8x8 feet pop-up targets powered by solar panels with remote monitoring from a desktop application. Wireless connectivity was enabled over 48 target nodes spanning over 6km in a desert environment.
- Programmed two degrees of freedom (DOF) robot capable of defect detection and classification in hollow cylindrical surfaces using a single computer vision and deep learning algorithm.
- Developed a simulator for UR5e robot, a six DOF robotic arm, using Simscape Multibody toolbox, Simulink, and MATLAB GUI designer.

https://pos.whitescastle.comGenesis AI — Agentic AI Platform with Wearable Integration
I built a multi-agent orchestration engine using LangGraph and LangChain to process ingested data and generate personalized "quests" — actionable daily goals tailored to the individual's health patterns, behavioral trends, and personal objectives. The system leverages RAG architecture with vector databases to maintain long-term user context and provide increasingly personalized recommendations over time.
The back end was built with Python and FastAPI, serving a React/TypeScript front end with real-time WebSocket connections for live wearable data streaming. I deployed it on AWS using containerized microservices with Docker, enabling horizontal scaling to support concurrent users. I integrated the OpenAI and Claude APIs for natural language understanding and quest generation, with custom fine-tuned models for health data interpretation.
SalesAICE — Autonomous AI Sales Agent Platform
I engineered the core AI engine with advanced objection handling using tactical empathy frameworks, real-time emotion detection from vocal cues, and adaptive conversation strategies. The system integrates with existing CRM platforms for automatic lead scoring, follow-up scheduling, and deal pipeline management.
I developed a multi-tier SaaS architecture (Starter, Core, Pro, Enterprise) with SDR automation, inbound call and message AI, closer AI, nurturing agent AI, and team trainer AI modules. It was built with Next.js and React for the front end, Python and FastAPI for back-end AI services, and OpenAI for natural language processing. The platform supports unlimited concurrent conversations with consistent quality, multi-channel integration (SMS, chat, voice), and enterprise-grade compliance and data governance.
MySpeakScore — AI-powered Public Speaking Assessment Platform
https://www.myspeakscore.ai/I built the AI scoring engine that analyzes multiple speaking dimensions, including clarity, confidence, structure, presence, and delivery patterns from video submissions. The system uses natural language processing and audio analysis to evaluate vocal cues, filler words, pacing, and overall communication effectiveness.
I developed the full-stack application with React for the front-end interface, Python and FastAPI for back-end video processing and AI analysis services, and integrated OpenAI models to generate warm, supportive feedback with human oversight for quality assurance. The platform supports multiple use cases, including everyday confidence-building, career preparation (interviews, presentations), and refinement of professional speaking skills. It was deployed on AWS, with secure video handling and processing pipelines.
Zlayt AI — AI-powered Legal Document Generation System
I built an intelligent document pipeline that processes case intake data and automatically drafts legal documents, including demand letters, complaints, and settlement agreements. The system uses vector databases to store and retrieve relevant legal precedents, statutes, and firm-specific templates, ensuring generated documents maintain legal accuracy and consistency with the firm's standards.
I developed the full-stack application using Python and FastAPI for the AI back end with LangChain for LLM orchestration, React and TypeScript for the front-end interface, and PostgreSQL for structured data storage. I integrated OpenAI GPT models for natural language generation with custom prompt engineering to maintain legal terminology and document formatting. It was deployed on AWS with enterprise-grade security to handle sensitive legal data and meet HIPAA-adjacent compliance requirements.
