> Senior Software Engineer (Java / Kotlin) | Distributed Systems | AWS | Ex-Mynd / Roofstock

Location: San Francisco Bay Area, United States
Profile: https://flows.cv/vladimirp

Senior Software Engineer with 15+ years of experience building backend systems in Kotlin/Java, focused on distributed systems, data platforms, and AWS.
 
At Roofstock (formerly Mynd), I built a large-scale property intelligence platform aggregating data for 100M+ U.S. properties from multiple sources. The system serves low-latency APIs and reduced property evaluation time by ~75%, enabling significantly higher throughput for analysts .
 
My work centers on:
 
 designing scalable backend systems and APIs (REST, gRPC) 
 solving data consistency and identity problems across multiple data sources 
 building event-driven architectures and data pipelines 
 working with SQL/NoSQL databases and AWS (S3, SQS, Lambda) 
 
I’ve also integrated LLM-based features into production workflows to automate validation, summarization, and improve data quality.
 
Earlier in my career, I led a team of engineers, which helps me work effectively across product, data, and engineering teams.
 
Currently exploring opportunities where I can work on large-scale systems and have meaningful product impact.

## Work Experience
### Senior Software Engineer @ Roofstock
Jan 2025 – Present | Oakland, CA
Mynd merged into Roofstock

- Built a centralized property intelligence platform aggregating 130M+ U.S. single-family homes (183 attributes, 13 data sources), served via gRPC/REST APIs on Snowflake Hybrid Tables. Cut property evaluation time from ~4 hours to ~1 hour, enabling analysts to process 4× more properties daily.
- Designed a field-level source priority framework to automatically resolve conflicts across overlapping data providers — each attribute governed by its most authoritative source without manual reconciliation.
- Engineered an event-driven enrichment pipeline (flood zones, school scores, AVMs, census, CBSA) using SQS to decouple 6 external enrichment services from the fast write path, keeping API latency within budget.
- Built a global property identifier (GRID) service to normalize and deduplicate addresses across 13 sources using 2-tier normalization (SmartyStreets → internal parser), deterministic hashing, and DB-level uniqueness constraints to guarantee zero duplicates under concurrent writes. Implemented multi-level caching that cut third-party address validation costs by ~5× (450M → 75M annual calls).

### Senior Software Engineer @ Mynd Management
Jan 2021 – Jan 2024 | Oakland, CA
- Designed and built the Service Request platform from scratch — the core repair/maintenance system for 40K+ properties. Built as a CQRS event-driven modular monolith (430+ command/event handlers, 40+ gRPC integrations), automating ~75% of workflows with multi-level approvals, vendor auto-dispatch, and SLA tracking.
- Built the Vendor Portal API (100+ endpoints) for 2,000+ vendors to manage end-to-end repair workflows. Reduced vendor onboarding time by 3× and job completion time by 25%.
Integrated OpenAI into the Service Request pipeline to auto-summarize work orders, validate resident-submitted requests, and verify vendor-reported work — reducing manual triage and QA effort across both sides.
- Built a multi-channel communication service processing 1M+ messages/month (SendGrid, Twilio, push, Slack) with event-driven async pipelines on DynamoDB and SQS.
- Architected a company-wide Geo API, migrating legacy geography models to U.S. Census Regions and Divisions. Led cross-team coordination and migration planning, reducing reporting prep time by 20%.

### Engineering Manager @ Mynd Management
Jan 2018 – Jan 2021 | Oakland, California, United States
Mentored engineers, established SDLC practices, and improved delivery predictability from 65% to 85%, reducing time-to-market by 20%.

### Senior Software Engineer @ Mynd Management
Jan 2016 – Jan 2018 | Oakland, California, United States

### Senior Software Engineer @ DataArt
Jan 2012 – Jan 2016 | London Area, United Kingdom
- Built a high-throughput messaging system (~20K orders/hour, millions of messages/day) for Ocado,
the UK's largest online-only grocer. Implemented bi-directional integration connecting warehouse
management to multiple e-commerce platforms using Kafka, Cassandra, and Apache Camel.
- Developed backend services and APIs for an Analytical Reporting Enterprise System for a major
Wall Street client, powering a spreadsheet-based interface that enabled analysts to query and
aggregate data from heterogeneous sources (SQL databases, external services) in real-time.

### Software Engineer @ Sberbank
Jan 2008 – Jan 2012
Developed various CLI tools for ETL processing, significantly improving data handling and processing efficiency.
Designed various monitoring systems, enabling proactive maintenance.
Collaborated with cross-functional teams to analyze and resolve technical issues, minimizing downtime and improving overall system reliability.
