Building scalable, AI-enabled platforms trusted by enterprise customers

I design, build, and modernize large-scale SaaS platforms — search, pricing intelligence, product matching, and analytics — and the AI-enabled engineering workflows around them. Over 20+ years, I’ve repeatedly been handed acquired products with serious problems and turned them into systems that win customers back: cutting matching query latency ~40%, saving $120K+/year in cloud spend, and shipping retention-critical capabilities for strategic enterprise accounts.

From modern React applications and GraphQL APIs to AI-assisted development workflows and cloud infrastructure, I enjoy turning ambitious ideas into reliable production systems.

About Me

I am a Senior Software Engineer with 20+ years of experience across search platforms, distributed data pipelines, and modern frontend architecture. At Wiser Solutions, LLC, I lead initiatives in product matching systems (React + GraphQL + NestJS), real-time analytics platforms (dbt + Trino + Apache Iceberg), and Elasticsearch/OpenSearch scaling, relevance tuning, and cost optimization.

Highlights of my recent work:

  • 🔎 Product turnaround: led the ground-up redesign of an acquired pricing product (Ruby on Rails → Elasticsearch/NestJS/React), restoring performance and bringing churned customers back into active use.
  • 💰 Cost efficiency: drove $120K+/year in cloud savings through OpenSearch/Elasticsearch ILM strategy, shard optimization, and gp3 migration — while improving P95 search latency and indexing throughput.
  • ⚡ Performance: cut query latency in matching APIs by ~40% through index design, analyzer tuning, and candidate-retrieval architecture.
  • 🤖 AI in practice: introduced AI-assisted development and review workflows (Claude Code, Windsurf) with automated quality gates, improving PR turnaround ~18%; designed an LLM-assisted validation workflow for product-match results with deterministic guardrails.
  • 📚 First author of “Scalable Software Architecture Design for Cloud-Native Applications,” IEEE CCWC 2026 (IEEE Xplore); practitioner publications in USENIX ;login: and O’Reilly Radar.
  • 🏅 16 peer reviews completed for IEEE and international journals.

Beyond delivery, I focus on scalability, reliability, and developer productivity — turning complex systems into maintainable engineering platforms and standards adopted org-wide.

Projects / Case Studies

🔹 Polaris Matching Platform

  • Built a React + GraphQL rule builder for enterprise-scale product matching.
  • Designed NestJS + PostgreSQL Matching Rules Service APIs, integrating with OpenSearch candidate retrieval.
  • Achieved 40% lower query latency and streamlined releases via Kubernetes + GitHub Actions.

🔹 Price Approvals — Enterprise Pricing Governance

  • Delivered a pricing approvals platform end-to-end (frontend, backend, storage) for a strategic enterprise account, helping retain the customer and protect recurring revenue.
  • Architected Elasticsearch data streams and lifecycle policies for historical retention, enabling auditable pricing governance at enterprise scale.

🔹 NGPI Data Models & Analytics

  • Architected dbt + Trino + Iceberg pipelines for hourly/daily aggregation of extraction, pricing, and error data.
  • Introduced partitioning (customer_id, extracted_at) and incremental models.
  • Enabled real-time insights across millions of records, boosting analytics productivity.

🔹 OpenSearch/Elasticsearch Cost & Performance

  • Designed ILM hot-warm tiers, shard balancing, analyzers (edge_ngram, keyword, lowercase), and nested mappings.
  • Migrated storage to gp3, optimized doc/value usage, and consolidated indices.
  • Saved >$120k/year in cloud spend while improving P95 search latency and indexing throughput.

🔹 Windsurf-Powered Developer Assistant

  • Created repo-aware prompts and PR/test scaffolds with Windsurf.
  • Automated code-mod recipes and “risk diff” summaries in PRs.
  • Reduced PR cycle time by ~18%, accelerating onboarding and delivery.’

🔹 Market Price Index (MPI) Redesign — Product Turnaround

  • Led the technical redesign of an acquired Ruby on Rails product with severe performance problems — rebuilt on Elasticsearch, NestJS, Redis, and React.
  • Restored usability, unlocked large-scale pricing analytics, and brought churned customers back into active use.

🔹 React Component Library

  • Developed TypeScript + Ant Design component system, shared across 3+ micro-frontends.
  • Integrated Storybook workflows and strict typing.
  • Increased developer velocity and UI consistency.
