Jacob SzwarcbergProduct leader · Full-stack builder

Product leader who builds.

I own the full product lifecycle—from strategy, discovery, and requirements through architecture, production code, and launch. That means my product decisions stay grounded in what it actually takes to deliver.

I’m at my best turning ambiguous, real-world problems into working products: commercial SaaS, AI tools, and hardware-software systems used by contractors and government agencies.

Experience

TransTech Systems Inc.

Principal Product Manager

I lead TransTech’s software portfolio end to end as the sole product manager and software engineer—owning contractor-facing SaaS, DOT workflow automation, and on-device gauge software. I also rebuilt calibration infrastructure used by our production team and distributors across 20 countries.

TransTech ConnectConstruction quality-control platformCommercial SaaS · 75,000+ measurements across five continents

A commercial field-to-office product for contractors collecting and acting on density measurements. I identified the opportunity, led discovery, and built the platform from concept through launch.

  • Delivered as a React web application, a React Native application for iOS and Android, and software running directly on the density gauge.
  • Built Bluetooth device pairing, GPS positioning, photo capture, and real-time gauge-to-cloud synchronization for field workflows.
  • Architected organizations, role-based access, subscriptions, and shared project data; the platform now holds more than 75,000 measurements collected across five continents.
  • Ran go-to-market for the platform, from positioning and sales calls through product demos, customer onboarding, and ongoing support for major national contractors.
AI Operations AgentTransTech Connect capability · PilotApproximately ten tools · action-taking · permission-aware

Designed and piloted a full tool-using agent over each organization’s live construction data. The agent runs an iterative Claude API tool loop that selects tools, evaluates their results, and continues through multi-step operational workflows.

  • Parses and uploads reports, assigns measurements to projects, retrieves answers from customer documents, summarizes shifts, analyzes performance, and recommends improvements.
  • Built with the Claude API, database functions, edge functions, asynchronous job queues, and context management for long-running operations.
  • Uses confidence-based action handling to decide which operations can run immediately and which require confirmation.
  • Gates every tool and data request using the user’s JWT and verified organization membership, preserving multi-tenant data boundaries.
Ames ConnectRoad profiling and DOT collaboration platformNebraska DOT pilot · contractor and agency collaboration

A separate multi-tenant product for contractors and state transportation agencies working through roadway analysis, submission, and pay-adjustment workflows, now being piloted with the Nebraska Department of Transportation.

  • Created shared projects that let contractors and DOT teams collaborate on the same road-profiling data.
  • Built GIS visualization, road-profile analysis, and IRI computation tools.
  • Automated state-specific submissions and pay calculations to reduce cost and turnaround time for both sides.
  • Lead go-to-market and the pilot process with DOTs and contractors, including discovery, sales conversations, demonstrations, onboarding, and direct customer support.
Gauge SoftwareOn-device measurement softwareRedesigned on-device experience · Wi-Fi synchronization

I redesigned the software running directly on TransTech’s density gauges, improving the field workflow and connecting the instrument more directly to the rest of the product ecosystem.

  • Redesigned the on-device experience used to collect, review, and manage density measurements in the field.
  • Added Wi-Fi synchronization so measurements can move directly from the gauge into connected cloud workflows.
  • Worked across measurement hardware, device software, data transfer, and the downstream web and mobile products.

Valinor Systems

Owner & Software Consultant

  • Rebuilt TransTech’s gauge calibration portal and helped complete a new gauge product, owning requirements, product strategy, technical documentation, and full-stack development.
Machine Shop ERPOperations and production controlGoogle Sheets → custom ERP · quote-to-invoice · ISO 9001 traceability

Designed and built a custom ERP that migrated a precision machine shop away from Google Sheets and connected its core business processes in one system—from quoting and customer orders through planning, production, inventory, and invoicing.

  • Standardized normal and Kanban orders, part revisions, work orders, machine scheduling, material tracking, and production reporting.
  • Built due-date-based inventory allocation to prioritize customer demand and prevent overcommitting finished goods.
  • Added production history, scrap reporting, controlled corrections, and revision-level traceability for ISO 9001 workflows.
  • Introduced semi-automated quoting, automated invoices and customer emails, and real-time visibility into production and inventory.

Viking Cruises

Technical Product Manager

  • Led a passenger health-screening integration that connected passenger records to a third-party telehealth provider through APIs and automated workflows, eliminating manual record reconciliation and reducing processing from hours to minutes.
  • Analyzed 24 months of delivery data and built workload dashboards to identify and remove software-team bottlenecks.
Yield & Inventory RedesignRevenue, occupancy, and overbooking riskSeven-figure oversell savings across annual sailings

Rebuilt the Yield department’s workflows for setting inventory availability and overage levels across sailings. The system had to maximize sellable inventory and occupancy while controlling the operational and financial risk of overbookings.

  • Mapped the existing yield process with the operational team and translated complex inventory decisions into a clearer product workflow.
  • Redesigned how inventory and overage levels were set so the business could sell more confidently without introducing avoidable oversell exposure.
  • The resulting process changes generated seven figures in oversell savings across annual sailings.
Live Partner Inventory APIThird-party travel distributionOn-demand live inventory · replaced daily CSV and FTP delivery

Designed and led development of an API that delivers current inventory on demand to third-party travel partners, replacing a once-daily CSV file distributed over FTP.

  • Moved partner integrations from stale daily snapshots to live availability at the moment inventory was requested.
  • Designed the API behavior and data flow, then led implementation across internal systems and external partner requirements.
  • Reduced dependence on batch-file delivery while giving travel partners more accurate information for customer searches and sales.

Accenture

Technology Business Analyst

  • Analyzed enterprise data from SAP, Confluence, and Salesforce and translated findings for executive stakeholders.
  • Maintained a 300-feature backlog connecting product requirements, teams, meetings, and roadmaps.

Ventur

Owner

  • Took a real-estate software company from idea through fundraising, hiring, product development, and launch.
  • Led five developers and documented integrations across ten external data providers.
