I'm a Senior Big Data and AI Engineer who builds production data platforms at petabyte scale and agentic AI systems that operate autonomously in production. Over the past nine years, I've worked across AWS, GCP, and Azure, delivering 50% faster pipelines, 40% cost reductions, and measurable automation of analytics workflows through LangGraph, Google ADK, and Databricks. On Upwork that translates into 21 completed contracts with near-perfect 5-star ratings and repeat enterprise clients — from quick, high-stakes database fixes to 100+ hour platform engagements. I take full ownership: architecture, cloud infrastructure, and delivery. WHAT CLIENTS HIRE ME FOR • Databases & DBA (deep specialty) — PostgreSQL, Citus, TimescaleDB, ClickHouse, and Trino: cluster design, replication and high availability, performance tuning, and migrations with zero data loss (RDS-to-Citus, 500GB+ PostgreSQL, ClickHouse shard/replication design). This is where my reviews are densest: - "His knowledge of ClickHouse Cluster is truly exceptional. He designed it exactly as needed." - "A game-changer — his analysis identified cost-saving opportunities and improved our solution architecture." (AWS database review) - "Super helpful even though it was new technology that's hard to find talent for." (pgvector on RDS Postgres) - "Did a fantastic job improving the database speed and migration." (500GB PostgreSQL migration) • Big-Data Platforms & Pipelines — Apache Spark, Trino, Apache Iceberg/Delta Lake, and Airflow + dbt on Kubernetes. I design petabyte-scale batch and streaming pipelines with the governance, lineage, observability, and SLOs production demands — typically 50% faster processing, 40% lower cost, and 99.9% uptime. • Production GenAI & Autonomous Agents — agentic systems on Google-ADK, LangChain, LangGraph, CrewAI, and MCP, plus RAG pipelines on Milvus, pgvector, and Pinecone. I ship them with real tracing and observability (LangFuse, Opik, MLflow) and guardrails — systems that run reliably, not demos. RECENT WORK • ClickHomes AI — a live real-estate analytics and lead-generation platform I architected end to end: a dual database (ClickHouse OLAP + PostgreSQL OLTP), a RESO-compliant ETL pipeline ingesting 9,500+ MLS listings with schema validation and lineage, a LangGraph ReAct AI search agent with streaming responses, multi-factor lead scoring, and Celery-powered email drip campaigns — deployed on Docker/Nginx and live in production. • TARA @ UXCam — an autonomous multi-agent analytics platform (Google-ADK + MCP) across 500+ mobile apps that cut analytics delivery time by 60% and manual effort by 75%, with RAG over 1M+ videos a month and full agent observability, governing 10TB+ of data per day on Databricks + Unity Catalog. HOW I WORK I design the architecture, stand up the cloud infrastructure, and deliver production-ready code — then make it observable, reliable, and cost-efficient. I communicate clearly and proactively across time zones, and I'm direct about trade-offs and timelines. TECH STACK Databases: PostgreSQL, Citus, TimescaleDB, ClickHouse, MySQL, MongoDB, Redis. Data: Apache Spark, Trino, Apache Iceberg, Delta Lake, Airflow, dbt, Kafka, Kinesis. AI/GenAI: Google-ADK, LangChain, LangGraph, CrewAI, AutoGen, MCP, RAG, Milvus, pgvector, Pinecone, Weaviate, MLflow, LangFuse, Opik.

I build production-grade Python-based data extraction and Web Scraping systems that survive where others fail. Projects range from focused data extraction tasks to large-scale Anti-Bot resilient infrastructures — each engineered for stability, performance, and long-term reliability. Over 12+ years, I’ve designed extraction systems processing 1B+ structured records across marketplaces, aggregators, AI/ML platforms, competitive intelligence systems, and enterprise catalogs. My systems are built using Python, Scrapy, Playwright, and Selenium — combining Web Scraper development, Data Mining, API Integration, and ETL pipeline design into stable, production-grade architectures. Whether you need a targeted scraping solution or a high-volume distributed pipeline, I architect the right system. When data becomes mission-critical — reliability matters more than code. ────────────── What I Build ────────────── • Custom Python Web Scraper and Data Extraction systems aligned with business logic • Scalable web crawlers handling anything from selective datasets to millions of pages • Continuous update pipelines (batch & incremental ETL workflows) • Queue-based distributed processing • High-concurrency execution models • API-based data extraction and system integrations • Clean ingestion into PostgreSQL / MySQL / APIs / cloud storage • Automated validation, deduplication & anomaly detection • Structured Data Mining pipelines for growing datasets You receive structured, business-ready datasets — not scripts to babysit. ────────────── Anti-Bot & Protection Layers ────────────── Modern platforms are protected.I work inside environments guarded by: - Cloudflare (403 / 429 / Turnstile) - DataDome behavioral detection - Akamai Bot Manager - PerimeterX - Reverse engineering of detection vectors & TLS/JA3 fingerprint alignment - Headless & browser fingerprint detection - hCaptcha / reCAPTCHA v3 Enterprise - Sustainable session & token lifecycle management This is not proxy swapping. This is controlled, sustainable access engineering. ────────────── Scale & Cost Control ────────────── As volume increases, scraping typically fails in two ways: 1) Stability collapses 2) Infrastructure & proxy costs explode I optimize concurrency models, routing logic, batching strategy, request distribution, and traffic patterns to maintain high throughput with controlled infrastructure load. Where relevant, I reduce proxy and infrastructure costs by up to 30% while preserving system stability. Result: High uptime. Predictable performance. Controlled margins. ────────────── Future-Proofing ────────────── Websites evolve. Structures change. Protection layers update. I implement structural drift monitoring and heartbeat systems that detect site changes before pipelines fail — shifting from reactive recovery to proactive control. Most developers fix scraping after it breaks. I design systems that minimize breakage from the start. ────────────── Who This Is For ────────────── • Founders building data-driven products • AI/ML teams requiring proprietary datasets • Businesses automating competitive intelligence or market tracking • Companies where reliable data access supports growth ────────────── Confidence Check ────────────── If needed, I can provide a working sample before full engagement to demonstrate data quality and bypass stability. To get started, send: - Target website(s) - Required data fields - Expected volume - Update frequency - Preferred output format Whether you're starting with a focused scraping task or building a large-scale data infrastructure — let’s build it properly.
