Hire the Best Python Consultants
in Canada

I’m a full stack engineer with Backend & AI having 7+ years of backend development experience and 3+ years working with AI/ML systems. I build and maintain production backend systems using Python, FastAPI, PostgreSQL, Docker and AWS, and I also develop and deliver AI features such as RAG pipelines, LLM integrations, AI agents and workflow automation. I already have 1,500+ hours of work history on Upwork and have worked with clients across the US, UK and UAE. Some of the work I’ve handled includes: • Python/FastAPI REST APIs and backend services • Debugging and improving existing backend applications • Data processing and automation using Python and pandas • PostgreSQL and MongoDB based applications • RAG pipelines and semantic search • OpenAI, Claude and other LLM integrations • AI agents and workflow automation • Document processing and knowledge retrieval • AI voice workflows using VAPI and Retell AI • Docker, AWS and CI/CD deployments • Async processing, background workers and microservices One area I particularly enjoy is connecting AI with real business workflows instead of building simple demo chatbots. For example, I have worked on AI-powered logistics/workflow systems where LLMs and retrieval pipelines were used to process business knowledge, automate quote-related workflows and support operational decisions. I have also worked on AI voice automation for outbound calling and lead engagement workflows using VAPI and Retell AI. My main stack Backend: Python, FastAPI, Django/DRF, Flask, Node.js AI/ML: OpenAI, Claude, LLMs, RAG, LangChain, AI Agents Data: PostgreSQL, MongoDB, MySQL, pandas, Vector Databases Cloud: AWS, Docker, GitHub Actions, CI/CD Other: REST APIs, authentication/RBAC, async processing, background jobs, microservices I’m comfortable working on both new systems and existing codebases — understanding the current implementation, debugging issues, improving reliability and delivering production-ready changes. If you have an existing Python backend that needs debugging, new API development, AI integration, RAG implementation, Microservices architecture, or automation, I’d be happy to take a look.

❓Are your GIS workflows slowing down your business? Contact me! 👉 I build automated GIS systems —helping organizations reduce costs, improve decision-making, and launch location-based products faster. Invite me for an interview & I will make a demo solution for you for free. Over the past 9+ years, I've built geospatial solutions for organizations including IBM, public health initiatives, a leading investment bank, and a high-growth AI startup. On Upwork, I've helped clients automate GIS workflows, build interactive mapping applications, and develop reliable spatial data pipelines that continue delivering value long after the project is complete. I don't just build maps—I build software systems powered by location intelligence. ⭐ What I Can Help You Build 🗺️ GIS Automation & Spatial ETL - Automated GIS workflows - Python automation scripts - Spatial ETL pipelines - GeoPandas & Shapely processing - Data validation and transformation - Batch processing for large geospatial datasets 🌍 Interactive Maps & GIS Applications - Mapbox & Leaflet web applications - Interactive dashboards - KML, GeoJSON, Shapefile processing - OpenStreetMap solutions - Territory mapping - Custom GIS tools 📊 Spatial Analytics & Decision Support - Location intelligence - Site selection analysis - Spatial reporting - Time-series analysis - Predictive geospatial analytics - Data visualization 🤖 AI + GIS Solutions - AI-powered GIS workflows - Intelligent document processing - OCR and spatial extraction - Geospatial data automation - Machine learning applications - LLM-powered geospatial tools ☁️ Backend & Cloud - PostGIS & PostgreSQL - FastAPI - REST APIs - AWS & Google Cloud - Docker - Database integration 🚀 Selected Project Experience Franchise Territory Automation - Built an automated Python and GeoPandas workflow that generated KML territory maps, validated geometries, and streamlined territory management.

Most e-commerce and SaaS companies lose 20–40% of their conversion data due to broken tracking and client-side signal loss. But insights are only as good as the data infrastructure underneath them. I bring Chemical Engineering rigor to data pipelines. I don't approach tracking as a marketer - I approach it as a process engineer. I apply Mass Balance and Failure Mode Analysis (FMEA) to find where the pipeline leaks and why - and now extend that into first-party Server-Side Tagging (SST) on GCP App Engine. Beyond fixing broken dashboards, I build hardened Web -> Server -> GA4 -> BigQuery pipelines that bypass ITP/ad-blockers and restore signal integrity before your data ever hits a report. 🚀 RECENT INTEGRITY WINS: - GA4 <-> Shopify Mass Balance & SST Proxy: Diagnosed a 4.95% phantom ROAS over-attribution rate, preventing ~$80,000 in phantom revenue from contaminating media models. - NL2SQL Semantic Layer Audit: Diagnosed 16 critical architectural failures across 5 bug classes in a BigQuery NLP layer - delivered to client engineering roadmap (5-star review). - SaaS Churn Risk Engine: Identified $250K monthly revenue at-risk using dual-method SQL redundancy validation - caught before it reached the model. 🛠 TECHNICAL STACK: GCP App Engine, Server-Side Tagging (SST), GA4, Google Tag Manager (Web & Server), Shopify, BigQuery, SQL, Python, Tableau 📫 TWO WAYS TO WORK TOGETHER: - GA4 Data Integrity Audit ($149): 47-point diagnostic, scored matrix, and developer-ready fix tickets (see my Project Catalog). - Strategy Consultation ($50): 30-minute triage call to identify your highest-priority tracking leak. Send me an invite or book a consultation with your site URL and top conversion event. I'll tell you within 24 hours if your tracking has a leak worth fixing - and whether you need a reconciliation audit, an SST proxy, or both.
