I design and operate production systems end to end — from Django and FastAPI services to AWS infrastructure, CI/CD pipelines, and AI integrations. My work sits at the intersection of backend engineering and DevOps: shipping reliable APIs, automating deployments, and making complex platforms easier to run in production.

About Me

I'm a hands-on engineer who enjoys owning problems from the database layer through to deployment and monitoring. Whether it's tuning PostgreSQL queries, wiring up HaloPSA integrations, or standing up Terraform-managed AWS environments, I focus on systems that stay maintainable long after the first release.

I'm a Backend & DevOps Engineer with 3.5+ years of experience building cloud-native applications for MSP and enterprise environments. Most of my work involves turning operational pain points — slow reports, fragile deploys, scattered logs — into automated, observable platforms that teams can depend on daily.

On the application side, I build with Python (Django, FastAPI), design REST APIs, and work closely with PostgreSQL, Redis, RabbitMQ, and MongoDB. On the infrastructure side, I provision and manage AWS (EC2, ECS, RDS, S3, Lambda), containerize with Docker, orchestrate with Kubernetes, and automate delivery through Jenkins, GitHub Actions, and Terraform.

I've also spent significant time integrating PSA platforms like HaloPSA, workflow tools such as Rewst and n8n, and AI services including LLMs, RAG pipelines, and ElevenLabs — always with an eye toward practical production use, not demos that fall apart under real load.

I hold an AWS Solutions Architect Associate certification (SAA-C03) and care deeply about the operational side of engineering: structured logging, useful alerts, clear runbooks, and deployments that don't wake anyone up at 2 a.m.

Certifications

I validate cloud architecture skills through industry certifications and keep them current as AWS services and best practices evolve. This certification reflects hands-on experience designing resilient, cost-aware systems on AWS — not just exam prep.

Technical Skills

These are the tools I reach for most often in production. I'm comfortable going deep on a stack rather than skimming many — especially where backend services, cloud infrastructure, and automation overlap.

Experience

I've spent the last several years at IT By Design working across backend services, cloud infrastructure, and automation for MSP operations — often bridging gaps between product engineering and the teams running systems in production.

IT BY DESIGN
Backend & DevOps Engineer
2023 — Present  ·  Full-time

Full-stack ownership across Python backends, AWS infrastructure, PSA integrations, and internal automation — supporting live customer workloads in a fast-moving MSP environment.

  • Built a live reporting engine that ingests and processes real-time HaloPSA data, replacing manual report generation and cutting reporting overhead by roughly 80%.
  • Led a PostgreSQL migration for core services — redesigning schemas, indexing strategies, and query patterns to improve performance by 60% while lowering infrastructure spend.
  • Designed end-to-end CI/CD pipelines with AWS, Jenkins, Docker, and Terraform, enabling repeatable builds, staged rollouts, and zero-downtime deployments.
  • Managed production infrastructure across EC2, ECS, RDS, and S3, including autoscaling policies, backup strategies, and cost-conscious resource sizing.
  • Implemented centralized observability with Splunk and CloudWatch — structured logging, dashboards, and alert routing that reduced mean time-to-detect incidents by 70%.
  • Built RAG-based AI assistants and knowledge tools using LLMs, vector databases, and LangChain — giving teams faster access to internal documentation and runbooks.
  • Automated operational workflows with Rewst and n8n, connecting HaloPSA, monitoring systems, and notification channels to reduce repetitive manual tasks.
  • Integrated ElevenLabs and other AI services into internal tooling where voice and conversational interfaces improved technician and support workflows.

Featured Projects

Selected work that reflects how I approach engineering problems — reliable backends, thoughtful infrastructure, and automation that saves real time for the people operating the system. Each project below combines multiple layers of the stack, not just a single tool or framework.

01

Document Intelligence RAG Chatbot

A document Q&A system that lets users upload files and ask natural-language questions against their content. Built with FastAPI and LangChain, it chunks documents, generates embeddings, stores vectors for retrieval, and uses RAG to ground LLM responses in source material — reducing hallucinations and supporting multi-document sessions.

02

AI Knowledge Assistant

An internal knowledge platform that indexes documentation, wikis, and runbooks so teams can search conversationally instead of digging through folders. Django powers the API layer, PostgreSQL stores metadata and conversation history, and Redis handles caching — with source attribution on every answer so users can verify responses.

Cloud Native CI/CD Platform

A deployment automation platform for shipping services to AWS with confidence. Jenkins orchestrates the pipeline, Docker packages applications, Terraform provisions infrastructure, and Kubernetes runs workloads in production. Supports blue-green releases, one-click rollbacks, and Slack notifications so the team always knows what shipped and when.

Live PSA Reporting Engine

A real-time reporting system built around HaloPSA data for MSP operations. Django and Celery handle ingestion and scheduled jobs, PostgreSQL stores aggregated metrics, RabbitMQ queues heavy workloads, and AWS hosts the production environment. Teams get dashboards and scheduled email reports without waiting on manual exports.

Centralized Observability Stack

A unified monitoring layer across Splunk, CloudWatch, Prometheus, and Grafana — giving one place to trace incidents from alert to root cause. Custom Python Lambdas enrich events, dashboards surface service health, and alert rules prioritize actionable signals over noise. Cut mean-time-to-detect production issues by 70%.

Infrastructure as Code Framework

A modular Terraform framework for spinning up complete AWS environments — VPC networking, security groups, ECS clusters, RDS databases, and S3 buckets — from reusable modules with remote state. Designed so new environments stay consistent, auditable, and quick to provision without copy-pasting boilerplate.

Pipeline Catch

A small arcade game built into this site — catch deploys and infrastructure components, avoid bugs and outages. It's a light break from reading, but also a nod to the kind of fast feedback loops I try to build into real pipelines: ship often, catch problems early, keep production healthy.
