About

Full Stack Engineer who builds AI-powered products

I am a Full Stack Engineer with more than eight years building production web and mobile applications for US and international clients, increasingly focused on integrating AI into real workflows rather than treating it as a demo. My recent work pairs deep product engineering with the compliance rigor that healthcare and security teams expect.

That path has run through government platforms, an offline first field operations app, a HIPAA compliant OR scheduling app deployed at a hospital, a multi branch school platform, and a cybersecurity compliance platform aligned with CMMC and NIST SP 800-171. I work across React, React Native, Vue, Node.js, Next.js, and PHP/Laravel on MongoDB and PostgreSQL, tested with Jest, React Testing Library, and Cypress, with hands on AWS, Docker, and CI/CD.

Today I am extending that foundation into AI powered features: LLM integration, prompt engineering, function and tool calling, RAG, and agent workflows with LangChain, LangGraph, and n8n, shipped so they hold up in regulated environments.

Recent Projects

A selection of production systems across compliance, healthcare, education, and AI engineering, with the outcome that mattered for each.

Cybersecurity Compliance Platform

Cybersecurity compliance SaaS · US

Compliance and assessment platform aligned with CMMC and NIST SP 800-171. Architected assessment workflows, scoring logic, evidence tracking, and an OpenAI pipeline that turns raw control language and uploaded evidence into scored gap findings and remediation recommendations.

TypeScriptReactNode.jsExpress.jsMongoDBPostgreSQLOpenAIAWSCypress

Outcome. Replaced manual first pass review with validated AI findings, shortening reviewer turnaround.

School Management SaaS

K-12 school chain · Texas

LMS, finance, and cafeteria modules for a multi branch school chain in Texas, plus a React Native parent app for lunch ordering, student progress tracking, and push alerts, all on shared Node.js and Express APIs.

TypeScriptReactReact NativeNode.jsExpress.jsMongoDBPostgreSQLQuickBooks

Outcome. Unified academic, financial, and identity data across branches so staff no longer reconcile systems by hand.

AI Voice Assistant for Clinical Scheduling

Healthcare · Hospital deployment

HIPAA compliant operating room scheduling app deployed at a hospital. Redesigned the event driven architecture to fix a critical timer desynchronization across devices and timezones, and integrated speech to text for an AI driven clinical voice response tool.

ReactReact NativeNode.jsEvent-Driven ArchitectureSpeech-to-TextHIPAA

Outcome. Timers stay in sync across every device and timezone, with the fix shipped to all client platforms through shared libraries.

AI Digital Twin

Personal project · github.com/bali48/bilal-twin-langgraph

RAG chatbot that answers questions about my professional background: a LangGraph retrieve and generate graph over a Chroma vector store, with checkpointed conversation memory and a Gradio UI. A parallel LangChain (LCEL) version compares both approaches.

PythonLangGraphLangChainChromaOpenAIGradio

Outcome. End to end RAG with graph based orchestration and persistent conversation memory.

LinkedIn Content Agent

Personal project

Agent workflow that picks a topic each weekday, researches it with a search enabled LLM agent, drafts a post grounded in verified profile facts, and publishes to LinkedIn only after email approval.

n8nOpenAISerpApiLinkedIn API

Outcome. Human in the loop automation: nothing publishes without explicit approval.

AI Document Q&A

Personal project

RAG based application that lets users upload a PDF and ask questions answered from the document content. Streaming responses, recursive text chunking with overlap, and vector search built end to end.

Next.jsTypeScriptVercel AI SDKOpenAI APIPython FastAPILangChainHNSWLib

Outcome. Demonstrates modern AI engineering: chunking, embeddings, vector storage, and streaming retrieval augmented generation.

Subscription Marketplace Platform

Personal project · Architecture design

A multi-domain lifestyle marketplace with a credits system, partner venue management, dynamic pricing, and a polymorphic booking engine. Designed as a systems architecture and investor MVP exercise.

NestJSPostgreSQLRedisMongoDBElasticsearchStripe ConnectReactAWS

Outcome. Systems design at scale: hybrid datastore, modular monolith with event driven communication, and an append only double entry credit ledger.
