Fullstack Developer · Software Architect · Applied AI

3 years building complete systems end to end. Today I integrate AI for real: agents, RAG and vectors.

Tracks

TRACK 01

Backend

Java · Spring Boot · Go · FastAPI

Hexagonal architecture, REST APIs, queues, Liquibase and Alembic migrations, multi-tenant isolation per branch.

TRACK 02

Frontend

Angular · React · Astro · TypeScript

Operational apps that keep working offline, real time over WebSockets, and landings with their own art direction.

TRACK 03

Data

PostgreSQL · pgvector · SQL Server · MongoDB

Modeling, querying and tuning in SQL Server and PostgreSQL; NoSQL with MongoDB Atlas; vectors with pgvector.

TRACK 04

AI

LangGraph · RAG · Agents · FastAPI

Tool-using agents, RAG over business data, vector search and WhatsApp sales assistants running in production.

TRACK 05

Graphic design

Composition · Retouching · Art direction

I edit and compose images myself: my interfaces and landings never come out of an AI template.

TRACK 06

Foreign trade

Customs · Tariffs · B2B sourcing

Foreign trade operations, tariff classification and technical negotiation with international suppliers.

CurrentAudreySoft

Founder & architect

I design, build and run a complete POS system in production, from the database to the server.

CommunityTraining

AI for engineers

Training sessions for engineers on how to use and integrate artificial intelligence in their work.

Keynote

Three years coding by hand. Now AI works for me, not instead of me.

I learned to build without shortcuts: architecture, databases, deployments, debugging in production. That is why I can push AI hard without losing control: I use it to move faster and I integrate it into systems as one more component, with agents, RAG and vectors, minding security, costs and data.

  • 01Tool-using agents that read and write in the real system
  • 02RAG and vector search with pgvector over business data
  • 03AI exposed behind authentication, rate limits and cost control

Exhibition

What I built. AudreySoft is in production and I run it.

AudreySoft

Founder · architect · sole developer

A POS system for stores, restaurants and services: sales, kitchen orders, recipe-based inventory, cash control, SUNAT e-invoicing, offline mode and an AI sales assistant on WhatsApp. It runs on my own server with CI/CD and zero-downtime deploys.

Track 05

Design Studio

I am also a graphic designer: I compose and retouch my products’ imagery. That is how a landing avoids looking like "another AI-made page": it has art direction.
