About & Focus

Build. Ship. Improve.

Portrait of Lawrence Dsouza

Software engineer focused on backend systems, AI applications, and real-time software. I like turning practical ideas into reliable products across APIs, computer vision, automation, and realtime user experiences.

01

Backend Systems

APIs, authentication, asynchronous services, databases, and realtime communication designed as one dependable system.

02

Applied AI

Voice agents, retrieval workflows, tool calling, and automation shaped around a real user task rather than a model demo.

03

Computer Vision

Detection, face embeddings, image retrieval, and camera pipelines that turn visual data into searchable information.

Selected work

Products, systems, and experiments I have built.

The interesting part is not the technology list. It is how the pieces were made to work together.

Backend + Digital Twin

Smart Workspace Optimization System

A workspace operations platform that brings bookings, occupancy, access management, and realtime facility analytics into one system.

Built with Next.js, FastAPI, MongoDB, WebSockets, HVAC optimization, and RAG-based natural language querying.

Agentic Voice AI

Nevira - Agentic Voice AI Assistant

A low-latency voice assistant that listens, reasons, calls tools, and responds naturally in realtime.

Includes wake-word detection, async tool execution, and function calling for search, weather, and email automation.

Other work

Four more projects across computer vision, mobile, and product engineering.

Computer Vision

Camera Analysis

A realtime camera-monitoring system that detects motion and faces, captures important events, and records searchable visitor activity.

Uses timestamps and SQLite-backed visitor data to keep captured events organized and searchable.

Python · OpenCV · SQLite
04

Computer Vision Search

Facial Recognition Image Retrieval

An image-retrieval pipeline that detects faces, converts them into numerical embeddings, and ranks matching photos with cosine similarity.

The workflow separates detection, embedding generation, indexing, caching, and retrieval so large photo collections can be searched without recomputing every face.

Mobile App

Members App for a Club

A mobile club-management app for member accounts, events, authentication, and shared realtime information.

Built Firebase-backed workflows for event tracking and member management.

Flutter · Firebase
06

Finance Tool

Student Budget Tracker

A student-focused budgeting tool for recording expenses, understanding spending patterns, and keeping day-to-day finances visible.

Built as a lightweight finance workflow with React, Firebase, and a responsive Tailwind UI.

Have something difficult to build?

Let’s make it work.

I am open to software engineering roles and selected projects involving backend systems, applied AI, realtime products, and computer vision.
