#About

I am the kind of engineer who does not just ship features — I care about what happens after deploy. Most of my work lives in the space between systems: APIs that need to be fast, integrations that cannot fail, and products used by real people under real load.

In practice, that means systems that stay fast as data grows, integrations that keep working when third-party services don't, and features that hold up once real users depend on them every day.

#Experience

Full Stack Software Engineer

AIQIA / Nexance

2024 – Present

Worked on production web systems in logistics and communication contexts, contributing to backend, frontend, integrations, and system maintenance and evolution.

  • Maintained and evolved a ticketing and messaging platform used for internal and external communication.
  • Participated in the transition from Flowly v1 to v2.
  • Improved ticket and message-related API flows by reducing repeated queries and grouping required data before database access.
  • Implemented message search and reference-based pagination for long conversation histories.
  • Worked with WhatsApp and email integrations, including webhook processing, IMAP-based email reading, and asynchronous processing.
  • Contributed to WMS flows using GraphQL federation, Apollo Router, Pub/Sub, Prisma, and PostgreSQL.

#Projects

Flowly

Customer support and business messaging platform — tickets, WhatsApp, email, all in one place.

What it does

A communication hub for internal and external business operations. Teams use it to manage support tickets, exchange messages over WhatsApp and email, and keep a full audit trail of every interaction.

Impact

Long conversations load without lag, support flows stay responsive under daily use, and every interaction stays searchable and auditable for the teams that depend on it.

WMS

Warehouse management system for logistics operations — receiving, storage, dispatch.

What it does

A warehouse management system that supports logistics operations end to end — receiving cargo, tracking storage, and dispatching orders.

Impact

Warehouse events stay consistent across services, and product and history flows keep working correctly as the operation scales.

WhatsApp API

Self-built WhatsApp integration library — clean adapter pattern, async processing.

Personal Project / Open Source Experiment

What it does

A small library that wraps WhatsApp messaging behind a clean interface, handling sending, receiving, and webhook-style processing.

Impact

Keeps messaging-provider details isolated, so the rest of an app can send and receive without knowing the underlying API.

#What I can build for you

Backend & APIs

Reliable services and APIs that stay fast as data and traffic grow.

System integrations

Connecting third-party systems — messaging, email, external services — so they keep working when others fail.

Web applications

Production web apps that real teams use every day, from interface to database.

Performance & scale

Finding and removing bottlenecks so systems hold up under real load.

Real-time & async

Live updates, event flows, and background processing that handle work behind the scenes.
