$700K+ delivered on Upwork across 145 projects with a 100% Job Success Score. I architect and ship production AI systems, Voice AI agents handling live calls under 2-second latency, computer vision platforms processing 8M+ daily events, and full-stack products running in production for years. What I build: 𝗩𝗼𝗶𝗰𝗲 𝗔𝗜 & 𝗖𝗼𝗻𝘃𝗲𝗿𝘀𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗔𝗴𝗲𝗻𝘁𝘀 Real-time voice pipelines combining speech-to-text, LLM reasoning, and natural voice synthesis. I built SloanConnect, an AI telephony platform that automates insurance verification calls end-to-end, navigates IVR systems, holds dynamic conversations with representatives, and scales to hundreds of concurrent calls. Sub-2-second response time, encrypted compliance handling, production-stable. 𝗖𝗼𝗺𝗽𝘂𝘁𝗲𝗿 𝗩𝗶𝘀𝗶𝗼𝗻 𝗮𝘁 𝗦𝗰𝗮𝗹𝗲 Lead AI Engineer on two production CV platforms: Adlytic - privacy-safe in-store retail analytics with GDPR-compliant pipelines, heatmaps, and POS integration, and SportsEye - real-time soccer analytics from broadcast feeds with 96% accuracy across player tracking, field mapping, and tactical metrics with zero on-field hardware. 𝗠𝗮𝗰𝗵𝗶𝗻𝗲 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 Hybrid recommendation engines on PySpark processing 8M+ daily impressions. NLP and sentiment systems wired into live dashboards. Healthcare process automation with HIPAA-aligned data handling. Models built to live in real environments, not notebooks. 𝗔𝗴𝗲𝗻𝘁𝗶𝗰 𝗟𝗟𝗠 𝗪𝗼𝗿𝗸𝗳𝗹𝗼𝘄𝘀 (𝗖𝗹𝗮𝘂𝗱𝗲, 𝗢𝗽𝗲𝗻𝗔𝗜, 𝗺𝘂𝗹𝘁𝗶-𝗺𝗼𝗱𝗲𝗹) End-to-end AI agents shipped to production: a Shopify + Amazon SP-API customer service agent with order lookup, refunds, returnless-refund policies, Slack/Email approval gates, and Klaviyo sync. Multi-step LLM pipelines with tool use, RAG, function calling, and human-in-the-loop checkpoints. I design these as systems, not single prompts, and I'm comfortable across Claude, OpenAI, and open-weight models depending on what fits the workload. 𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸 𝗙𝗼𝘂𝗻𝗱𝗮𝘁𝗶𝗼𝗻𝘀 Every AI product needs scaffolding that holds. I've shipped Django/Node/React/Next.js platforms that ran 3+ years in production, Alchemist Real Estate, audIT.app, and a long-running B2B SaaS that grew from MVP to hundreds of users across $195K+ in contracted development. Distributed backends, REST/GraphQL APIs, AWS-native deployment, data pipelines, and the DevOps to keep them stable. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 As Lead Engineering Architect, I stay hands-on through the whole lifecycle, discovery, architecture, core implementation, deployment, and the long tail. I don't hand off and disappear. Most of my Upwork work is repeat business or long contracts measured in years, not weeks. If you're building a Voice AI agent, a computer vision platform, an LLM-driven workflow, or a full-stack AI product that needs to survive real load - let's talk.

I am an experienced full stack data and backend engineer. My background and skills include: - Expert in Python, SQL and NodeJS - Certified AWS Cloud Practitioner and studying for exams in Certified Developer, Solutions Architect, SysOps Administrator and Data Analytics - Two MScs in Mathematics and Data Science - Databases (Postgres, PostGIS, Aurora, DynamoDB, MySQL, Mongo, Redis, Snowflake, Redshift, Neo4j) and ORMs - Cloud Infrastructure (AWS, GCP, Terraform) - APIs (FastAPI, Flask, Express, GraphQL) - Orchestration (Airflow, Kubernetes) - Pub/Sub + Queuing (Kafka, RabbitMQ) - Version control Git - CI/CD (Docker, Github Actions, Jenkins) - GIS (Postgis, Shapely, GDAL, H3) - Web crawling (Scrapy, custom crawlers in Python/Node/Go) - PySpark/AWS EMR/AWS Batch I have worked in data and tech for 4 years including full time roles as a Data Scientist, Data Engineer, Backend Engineer and Head of Data. In a previous life I worked investment banking in Sales and Trading for 4 years. Previous projects include: - Designing and building a client a booking engine to allow them to expand into the reservation and beauty treatment business (GCP, Python, Postgres, Redis and FastAPI). - Assisted a bottling company in expanding their tech capabilities by moving them from spreadsheets into the cloud and developing APIs to automate their business with other partners (Python, Postgres, AWS, FastAPI). - Refactored an employers crawling system to make it more efficient. Previously each data entity was crawled on a regular frequency, but the vast majority of entities very rarely changed leading to unnecessary crawling and resource use. The refactor took into account the changes in the data and how often they occurred to predict the next optimal time to crawl resulting in a 15% reduction in cloud costs (AWS, Postgres, NodeJS, Python, RabbitMQ). - Developed a streaming change data capture pipeline handling 50 million unique payloads per day resulting in a +15% reduction in total cloud costs while allowing live data to be available to customers (AWS, Python, NodeJS, RabbitMQ, Postgres, Snowflake, Airflow) - Created a data architecture to allow aggregation of geospatial time series for any possible geographic polygon across +20bn global data points in sub-second time (AWS, Clickhouse, Python, FastAPI, Postgres, Uber H3, Redis) - Created an autonomous on-demand Excel and PDF reporting system to allow a sales team to generate their own reports from data stores with no required input from developers (AWS, Python) - Developer multiple machine learning models running production including an age/gender classification for faces in photos (Python, Keras, GCP), entity resolution system combining tabular, text and image embeddings to deduplicate +30mm listings across multiple provider platforms (AWS, Python, PyTorch, RabbitMQ, Neo4j, Postgres)

I'm a data engineer and database expert with a passion for data and extensive experience across a broad skill set: * Expert in SQL (Oracle, Postgres, MySQL, Redshift, SQL Server, Snowflake, Clickhouse), PL/SQL / PL/pgSQL, Data Modelling, Data Warehousing, query optimization / performance tuning, and Oracle APEX. * Competent across the following cloud platforms - AWS, Azure and OCI. * Proficient in Python, Terraform, Kafka, DBT, NoSQL and graph databases (MongoDB, Neo4J), Azure Devops Pipelines / CI/CD, Kubernetes, Docker, orchestration tools (Airflow, Prefect) I'm a great communicator and have a proven track record of exceeding client expectations. I'm a native English speaker and I believe communication is key, especially when working remote. I look forward to speaking with you.
