Engineer & Develop

Big Data & Analytics Engineering

Your data is piling up in S3, Redshift is timing out on every report, and your analysts are still waiting three days for a query that should run in three minutes. Flentas designs and builds your end-to-end data engineering stack — from ingestion and transformation to warehousing, BI, and ML-ready pipelines — so your business runs on insight, not gut feel.

The Reality

Why Does Every Report Take Three Days?

Your data is piling up in S3, Redshift times out on every report, and analysts wait days for a query that should take minutes.

Reports take days, not seconds

Nobody owns the pipeline, so a question that should run in three minutes waits three days in a queue.

Three ETL jobs, two warehouses

Overlapping stacks and a spreadsheet nobody trusts mean every metric has three answers.

Redshift times out on every query

Raw, processed and aggregated data all hit the same cluster, and full-table scans burn the budget.

The query bill keeps climbing

Unoptimized clusters and unpartitioned tables make every dashboard refresh a line on the invoice.

ML never leaves the notebook

Models trained in Jupyter never reach production because there's no pipeline to carry them.

PII has no lineage

Personal data scattered across dozens of tables with no catalog is a DPDP audit waiting to happen.

Key Benefits

From Data Chaos to a Single Source of Truth

  • Stop Waiting for Insights

    Reports that should take seconds are taking days because nobody owns the pipeline. Production-grade data pipelines on AWS — ingestion to dashboard — give every team accurate, real-time answers without raising a ticket.

  • Fix the Broken Data Stack

    Three ETL jobs, two data warehouses, and a spreadsheet nobody trusts. Flentas consolidates your data architecture onto a unified, scalable AWS stack — one source of truth your analysts, engineers, and executives all agree on.

  • Cut the Query Bill in Half

    Unoptimised Redshift clusters and full-table scans are burning your cloud budget. Flentas right-sizes your warehouse, partitions your data lake, and configures serverless query execution — up to 60% reduction in compute costs.

  • Put ML Where It Belongs — in Production

    Models trained in notebooks that never reach production. SageMaker-powered ML pipelines with automated retraining, feature stores, and inference endpoints — so your models actually drive decisions, not quarterly slide decks.

How It Works

How We Build Your Data Platform

  1. 1

    Audit the Data Chaos

    Most teams don't know what data they have, where it lives, or why three systems disagree on the same metric. A data architecture audit catalogues sources, maps flows, and scores data quality — so we fix the right problems first.

  2. 2

    Build Pipelines That Don't Break

    Brittle cron jobs and manual ETL scripts fail silently until a stakeholder notices the dashboard is stale. Event-driven ingestion pipelines using AWS Glue, Kinesis, and Lambda — with automated alerting and retry logic so data flows reliably.

  3. 3

    Land Data in the Right Store

    Raw, processed, and aggregated data all queried from the same place is why your Redshift cluster times out. Flentas designs your storage architecture — S3 data lake, Redshift warehouse, and Athena for serverless ad-hoc queries — giving each workload the right engine.

  4. 4

    Deliver Dashboards That Get Used

    BI tools nobody trusts because the numbers change on every refresh. Semantic layer definitions, certified datasets, and QuickSight or Tableau dashboards with row-level security — finance, operations, and product all see the same truth.

  5. 5

    Take ML From Notebook to Production

    Data science prototypes living in Jupyter notebooks that never ship. SageMaker pipelines with feature stores, model registries, A/B testing endpoints, and automated retraining — your models run in production, not in a slide deck.

  6. 6

    Govern Data Before Regulators Do

    PII scattered across 14 tables with no lineage documentation is a DPDP audit waiting to happen. AWS Lake Formation access controls, Glue Data Catalog lineage, and data masking policies make your data estate governed, documented, and defensible.

Case Studies

Where Big Data & Analytics Engineering Makes a Difference

Fintech

BFSI / Fintech

60% Reduction in Incident TAT

Loan origination data siloed across five systems with no single risk view — a serverless analytics pipeline on AWS delivers real-time credit decisioning dashboards, cutting analyst query time by 80%.

Gaming

Gaming / High-Traffic Platforms

35% In-App Purchase Conversion Uplift

Millions of game events per second with no monetisation visibility — a Kinesis-to-S3-to-Athena pipeline enabled real-time player behaviour analytics and a 35% uplift in in-app purchase conversion.

SaaS

SaaS / Subscription Platforms

4 hrs Reporting Time, Down from 3 Days

Churn prediction model trained quarterly on stale data — automated SageMaker retraining with daily feature refresh reduced monthly churn by 18% within two quarters.

E-Commerce / Retail

Daily sales reports delivered the following afternoon via emailed spreadsheets — an automated QuickSight pipeline gives merchandising teams live inventory and revenue visibility across 12 product categories.

“Our analysts were spending three days every week just preparing data for reports that were already out of date by the time they landed in inboxes. Flentas redesigned our entire data pipeline on AWS — Glue, Redshift, QuickSight — in under eight weeks. Reports that used to take three days now run in under four hours. The dashboards update every 15 minutes. We made better pricing decisions in the first month than we had in the previous two quarters combined.”
