why hire me

I turn high-throughput data into systems teams can trust.

A backend engineer focused on measurable results — faster systems, fewer production surprises, and clean event-driven architecture. Open to remote backend and distributed-systems roles.

Impact you can measure

I led a ClickHouse migration that made IoT analytics 99%+ faster — real numbers, not buzzwords.

Reliability by default

Real-time alarms, observability, and event-driven services built to stay predictable under heavy load.

Range across the stack

From RabbitMQ pipelines and microservices to production platforms — IBMS, Ignite, and Facilitrol-X.

01 // about

Backend engineer for data-heavy systems

Backend software engineer specializing in distributed systems, event-driven architecture, and high-throughput data pipelines. At Unifi Solutions I re-architected IoT analytics around ClickHouse for 99%+ faster queries, shipped real-time alarm & alerting over live sensor streams, and build resilient microservices with Node.js, TypeScript, NestJS, and RabbitMQ.

I care about systems that stay fast and predictable under real load. That means measuring before optimizing, keeping event-driven services loosely coupled and debuggable, and treating observability — Grafana dashboards, metrics, traceable IoT events — as a first-class part of the work, not an afterthought.

What I focus on

Performance

Profiling hot paths and re-architecting data layers for sub-second queries at scale.

Reliability

Resilient services with real-time alarms and alerting that catch failures early.

Event-driven design

Clean RabbitMQ messaging that decouples high-throughput IoT workflows.

Observability

Grafana dashboards and metrics that make production behavior easy to reason about.

Where I've worked

Mid-Senior Backend Developer
Unifi Solutions
Apr 2024 — PresentRemote
Backend engineering across large-scale IoT, asset-management, and predictive-maintenance platforms.
Led an analytics performance initiative: re-architected IoT analytics around ClickHouse, achieving 99%+ faster queries versus the previous solution and unlocking interactive dashboards over high-volume sensor data.
Designed and maintained real-time alarm & alerting logic over live IoT readings and thresholds, enabling early detection of abnormal conditions and proactive maintenance workflows.
Built and operated event-driven microservices on RabbitMQ — consuming, processing, and debugging real-time IoT events and asset-lifecycle workflows at scale.
Delivered backend features across large-scale asset-management & predictive-maintenance systems: IBMS, Ignite Meter, Ignite Shield, and Facilitrol-X.
Drove performance profiling and bottleneck analysis on high-throughput services, and improved observability with Grafana dashboards and metrics for faster production debugging.
Contributed backend features and integrations to ClimaCert-X, an AI + IoT sustainability-certification platform.

Selected work

A few things I've built — from production e-menu systems to AI research.

Product · 2023

QBite

Eco-friendly digital e-menu platform

A digital e-menu system that replaces printed menus with real-time, multilingual menus restaurants can update instantly — cutting waste while speeding up service.

Led the team building the platform end to end, cutting paper use by 90% and menu-update costs by 50%.

Improved order efficiency by 15% through a streamlined, mobile-first ordering flow.

Ran a process re-engineering effort to consolidate fragmented service flows into one pipeline.
