In a notable instance, I optimized a critical workflow by transitioning it from Python to high-performance Trino (formerly Presto) SQL Engine for Big Data. This transformation led to a remarkable reduction in execution time, plummeting from 2 hours and 40 minutes to just 6 minutes - this means that productivity increased by approximately 96.25%. This substantial enhancement was achieved through the Presto engine's superior parallel data processing capabilities. The outcome not only accelerated information processing but also resulted in significant cost savings for the client. This achievement underscores my proficiency in optimizing processes and leveraging cutting-edge technologies to deliver tangible benefits.
Conducted comprehensive evaluations and assessments, ultimately recommending the adoption of Snowflake database.
Identified critical performance issues with the Snowflake Query Optimizer for queries exceeding one minute, leading to the development and implementation of a targeted solution.
Demonstrated exceptional problem-solving skills by optimizing a typical query for updating 10 rows in a one-terabyte table from 6 minutes to an impressive 5 seconds, significantly enhancing operational efficiency.
Successfully resolved user interface delays, a critical concern, by implementing a caching strategy leveraging the MySQL database with MEMORY storage engine, ensuring near-instantaneous data retrieval even for big datasets. This approach achieved comparable performance to Redis, with the added advantage of a SQL interface.
----
Spearheaded workflow optimization initiatives for one of the largest tobacco corporations, focusing on Treasure Data's Enterprise Customer Data Platform.
Successfully transitioned tasks previously implemented in Python to leverage the power of Trino (formerly Presto), a high-performance SQL Engine for Big Data, resulting in remarkable performance enhancements ranging from 10 to 40 times.
Notably, a task with an initial runtime of 13-15 minutes was streamlined to achieve completion within an impressive 18-20 seconds, exemplifying a substantial boost in operational efficiency and productivity.
---
Led critical initiatives for one of the largest fintech companies specializing in investment management solutions.
Directed the development of robust monitoring and logging systems for Snowflake, ensuring optimal performance and reliability.
Formulated disaster recovery strategies for mission-critical databases including MS SQL Server, Confluent (cloud Kafka), Atlas MongoDB, and Snowflake, bolstering data integrity and security measures.
Engineered specialized SQL scripts for comprehensive Snowflake monitoring, providing real-time insights into system performance and stability.
Orchestrated seamless integration of Snowflake with Rapid7 for effective logging and incident response procedures.
Delivered strategic recommendations for modifying configurations to reduce RTO and RPO in the event of a disaster recovery scenario.
Interested in working with big data. I love to learn new tools and apply them in work.
I am looking for a long-term, stable and reliable relationship.
I like to work with data, analyze it, look for patterns and relationships.
