I build data platforms that work at scale and keep working as your
business grows.
Over the past 10 years I've served as the lead or founding data engineer
across fintech, e-commerce, ride-hail, legal tech, and cybersecurity
companies. That means I've designed systems from scratch, made architecture
decisions with no one to fall back on, and delivered platforms that
product teams actually use.
Here's what I typically get hired to do:
→ Build greenfield data platforms on AWS or GCP from the ground up
→ Design and ship production ETL/ELT pipelines (Airflow, Dagster, dbt)
→ Set up scalable warehouses and governance (Snowflake, BigQuery, Redshift)
→ Implement real-time streaming pipelines (Kafka, Spark Streaming, CDC)
→ Build AI-powered data applications (RAG, LLMs, LangChain, vector DBs)
→ Fix broken or unreliable pipelines and make them production-grade
→ Architect cloud infrastructure on AWS, GCP, Azure (Terraform, Kubernetes)
Recent work includes:
- Led data platform engineering for a US e-commerce company processing
billions of events daily. I re-architected ingestion pipelines, built
Snowflake governance from scratch, introduced Prometheus monitoring and
CI/CD standards across the platform.
- Built a full data platform on GCP (BigQuery, Dataproc, Airflow) for a
music streaming company. Firebase, AppsFlyer, and app store data all
flowing into one warehouse within weeks.
- Designed an AWS data platform for a ride-hail company managing 500+
streaming and 700+ batch jobs — including a self-serve portal that
replaced multi-step CLI workflows for engineers.
- Built a legal AI search engine using LangChain, Pinecone, and RAG —
full pipeline from document ingestion to LLM-generated answers, deployed
on AWS with auto-scaling.
- Built an AI inventory insights agent for a US automotive company —
multi-source data pipelines, real-time APIs, conversational interface.
I work in English daily, communicate proactively, and deliver production-
ready code — not prototypes. I'm used to working directly with CTOs and
technical leads in US and European time zones.
Tools I work with regularly:
Python · SQL · Airflow · Dagster · dbt · Snowflake · BigQuery · Spark · Meltano ·
Kafka · AWS (S3, EMR, Glue, ECS, Lambda, EC2, EKS) · Databricks · GCP · Azure
Terraform · Docker · Kubernetes · LangChain · FastAPI · MLflow · Weaviate, Celery
If you're building a data platform, fixing one, or adding AI/ML
capabilities to your stack, let's talk.

Integrated systems rarely break on the first successful API call. They break three weeks later: a failed Shopify webhook, an ERP order that never synced, a CRM contact missing from the pipeline, or POS inventory that no longer matches the store.
I build and fix the middleware/API layer behind those systems.
My strongest work is around Shopify, ERP, CRM, POS, and Laravel-based backend systems where product data, orders, inventory, customers, payments, and reporting all need to stay aligned.
What I usually handle:
- Shopify / Shopify Plus integrations and custom commerce workflows
- ERP and CRM syncs: Acumatica, Salesforce, Zoho, HubSpot, SAP-style systems
- POS and inventory workflows: Clover, store operations, loyalty, order flows
- Laravel/PHP middleware, APIs, webhooks, queues, cron jobs, retries, and logs
- Admin dashboards, reporting panels, and operational data models
- Production debugging where the issue is hidden across multiple systems
Relevant background:
- Built and supported systems handling 24k+ products, 3M+ users, and 2,000+ locations
- Led technical delivery across teams of 20+
- Worked across Shopify, Shopify Plus, Magento, BigCommerce, Acumatica, Salesforce, Zoho, Clover POS, Laravel, REST/GraphQL APIs, PostgreSQL, MySQL, AWS, Firebase, and payment systems
I also take on SaaS MVPs and React Native app work when the project depends on backend architecture, integrations, subscriptions, analytics, or production stability.
If your store, ERP, CRM, POS, or internal dashboard is held together by fragile syncs and unclear data flow, I can help trace where it breaks and make the system reliable.

How to Hire Top ColdFusion Developers
How to hire ColdFusion developers
Got a need for web application development speed? A ColdFusion developer can help you whip up a modern web app in a snap.
So how do you hire ColdFusion developers? What follows are some tips for finding top ColdFusion developers on Upwork.
How to shortlist ColdFusion development professionals
As you’re browsing available ColdFusion development consultants, it can be helpful to develop a shortlist of the contractors you may want to interview. You can screen profiles on criteria such as:
Technology fit. You want a ColdFusion developer who understands the tools, frameworks, and libraries you wish to use in your site.
Project experience. Screen candidate profiles for specific skills and experience (e.g., integrating ColdFusion with React).
Feedback. Check reviews from past clients for glowing testimonials or red flags that can tell you what it’s like to work with a particular ColdFusion developer.
How to write an effective ColdFusion job post
With a clear picture of your ideal ColdFusion developer in mind, it’s time to write that job post. Although you don’t need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project.
An effective ColdFusion developer job post should include:
Scope of work: From single-page applications (SPAs) to mobile apps, list all the deliverables you’ll need.
Project length: Your job post should indicate whether this is a smaller or larger project.
Background: If you prefer experience with certain libraries, tools, or frameworks, mention this here.
Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.

Why hire ColdFusion developers?
The trick to finding top ColdFusion developers is to identify your needs. Do you need help integrating a ColdFusion back end with an Angular front end to create a dynamic SPA? Or are you building a mobile app with CFMobile? The cost of your project will depend largely on your scope of work and the specific skills needed to bring your project to life.

How much does it cost to hire a ColdFusion developer?
Rates can vary due to many factors, including expertise and experience, location, and market conditions.
An experienced ColdFusion developer may command higher fees but also work faster, have more-specialized areas of expertise, and deliver higher-quality work.
A contractor who is still in the process of building a client base may price their ColdFusion development services more competitively.
Which one is right for you will depend on the specifics of your project.
