Data Architect | Full-Stack Attribution: Segment ➔ Appsflyer ➔ Mixpanel ➔ BigQuery ➔ Looker Studio
I architect end-to-end data pipelines that turn fragmented user interactions into a single source of truth. My expertise lies in the technical implementation of the Modern Data Stack, moving beyond basic tracking to building robust ETL/ELT workflows.
Core Technical Workflow:
Data Collection & Orchestration: Full-stack Segment implementation (Protocols & Functions) to centralize data streams from web and mobile.
Mobile Attribution: Expert AppsFlyer configuration, including SDK event mapping, OneLink smart scripts, and cost-aggregation.
Behavioral Analytics: Advanced tracking in Mixpanel and Amplitude to monitor complex conversion funnels, retention cohorts, and user journeys.
Data Warehousing: Automating data pipelines from Segment/Mixpanel into BigQuery for advanced modeling and long-term storage.
Visualization: Engineering high-fidelity Looker Studio dashboards that sync directly with BigQuery to track CAC, ROAS, and LTV.
By bridging the gap between raw tracking and warehouse-level reporting, I ensure your marketing spend on Google Ads and Meta Ads is backed by 100% accurate, multi-touch attribution.

4+ years building BI end-to-end Infrastructure. I sit with the ambiguity, ask what your team hasn't, and translate fuzzy business goals into a clear data model and KPI framework that holds up under scrutiny.
🧠 𝐖𝐡𝐚𝐭 𝐈 𝐛𝐫𝐢𝐧𝐠 𝐭𝐨 𝐲𝐨𝐮𝐫 𝐭𝐞𝐚𝐦
🔹 Ambiguity → Clarity: I define the right questions and metrics before building anything, so you measure what matters, not what's easy.
🔹 Semantic & Data Modeling: Star schemas, slowly-changing dimensions, reconciled grain, single source of truth
🔹 Scalable Architecture: Pipelines and models designed for "Day 2", maintainable, cost-aware, documented, built to grow instead of breaking at scale.
🔹 Context Integration: I unify Stripe, Shopify, Zoho, GA4, Ads platforms, etc. and CRMs into one coherent ecosystem that mirrors how your business actually operates.
🔹 Narrative & Decision Design: Every visual answers a business question and points to an action, analysis a CEO can act on in seconds.
⚙️ 𝗧𝗲𝗰𝗵𝗻𝗶𝗰𝗮𝗹 𝗧𝗼𝗼𝗹𝗯𝗼𝘅
🔹 BI & Viz: Power BI, Looker Studio, Zoho Analytics, Metabase, Apache Superset, Domo, Databox
🔹 Modeling & Query: SQL, DAX, Power Query (M), Python, dbt, Excel
🔹 Warehousing: BigQuery, Cloud SQL, Snowflake, SQL Server, MySQL, Firebase
🔹 Pipelines & ETL: Make, n8n, Fivetran, Apps Script, Cloud Run, Windsor AI, Coupler IO, Supermetrics
🔹 Sources: Stripe, Shopify, Zoho CRM, GA4, Google/Meta/TikTok Ads, Search Console, etc.
🔹 AI layer (the plus): OpenAI & Claude APIs, Claude Code, Codex, conversational analytics, anomaly detection, predictive models, and agent workflows for automated briefings & alerts
🚀 𝗪𝗵𝗮𝘁 𝗦𝗲𝘁𝘀 𝗠𝗲 𝗔𝗽𝗮𝗿𝘁
🔹 Business-first, not tool-first: I start with your objectives and constraints, not your dataset.
🔹 End-to-end ownership: From auditing sources and defining KPIs to modeling, building, and publishing, I run the full lifecycle.
🔹 Transparency: You own your data and infrastructure. I document every step, so nothing is a black box.
🔹 AI as leverage, not a gimmick: I automate the repetitive parts so the strategic parts get more of my attention.
⭐ 𝗪𝗵𝘆 𝗖𝗹𝗶𝗲𝗻𝘁𝘀 𝗦𝘁𝗮𝘆
🔹 Reliable communication and clear expectations , no micromanagement needed.
🔹 Insights in plain language, for technical and non-technical stakeholders alike.
🔹 Proactive: I diagnose and recommend, not just deliver charts.
🔹 Consistent delivery, on time, with care.
💡 𝗟𝗲𝘁'𝘀 𝗕𝘂𝗶𝗹𝗱 𝗬𝗼𝘂𝗿 𝗗𝗲𝗰𝗶𝘀𝗶𝗼𝗻 𝗦𝘆𝘀𝘁𝗲𝗺
If your business generates data but not clarity, let's fix that. I'll design the model, architecture, and dissemination layer that turn your numbers into a durable competitive advantage, clear, scalable, and genuinely yours.

Hi, I'm Param — Top Rated Product & Marketing Analytics Expert helping businesses build reliable tracking, fix attribution issues, and turn data into measurable growth with PostHog, Mixpanel, Amplitude, GA4, GTM, AppsFlyer, BigQuery, and Looker Studio.
If your tracking is broken, conversions don't match across platforms, or you can't trust your analytics data, I can help you build an analytics foundation you can rely on.
I work with SaaS, eCommerce, and mobile app companies to build reliable analytics systems that give marketing, product, and leadership teams confidence in their data. Whether you're launching analytics from scratch, auditing an existing setup, or fixing attribution issues, I help you transform fragmented data into accurate, actionable insights.
From event tracking and server-side implementations to mobile attribution, data pipelines, and executive dashboards, I deliver analytics solutions that are accurate, scalable, and built for long-term growth.
I work closely with founders, marketers, product managers, and developers to design tracking strategies, validate every event, and build dashboards that support confident business decisions.
✅ Services I Offer

Whether it's GA4 revenue not matching Shopify or Stripe, duplicated events, unreliable product analytics, or dashboards showing incorrect numbers, I make sure your data tells the real story.
✅ My Process
Every project starts with understanding your business goals, KPIs, and existing tracking setup. I then create a scalable tracking plan that aligns with your marketing and product objectives.
Once the strategy is defined, I implement, validate, and thoroughly test every event, conversion, and attribution flow. Finally, I deliver clear dashboards, documentation, and ongoing support to ensure long-term success.

I help ecommerce and marketing teams get clean, reliable data they can actually act on — from tagging and tracking setup to dashboards and reporting.
My work spans the full analytics stack: auditing and rebuilding GTM containers, implementing GA4 with proper ecommerce tracking, configuring Consent Mode v2 for GDPR/CCPA compliance, and building Looker Studio dashboards connected to sources like Snowflake, BigQuery, and Google Ads.
Recent projects include a full tag and attribution audit for a multi-storefront DTC brand (identifying a rogue GA4 property and cross-domain tracking breaks), a Consent Management Platform implementation (Cookiebot/CookieYes) across WordPress and Shopify sites with Consent Mode v2, and Looker Studio dashboards pulling from Snowflake data warehouses.

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

capabilities to your stack, let's talk.
