Work Experience
Software Development Engineer-II
Amazon Web Services (AWS)
- Delivered real-time manufacturing visibility across 8 global sites by building an event-driven pipeline processing hundreds of millions of shop floor events daily into DocumentDB and OpenSearch for sub-second search across 2TB+ of records.
- Delivered live views of inventory consumption, rack build quality, and assembly-line state by building an operational tracking surface, enabling teams to pinpoint production status at any point in the build chain.
- Delivered executive visibility into rack and server delivery commitments by surfacing facility throughput, production timelines, and on-time delivery performance, replacing ad hoc reporting with a single always-current source of truth.
- Delivered full component traceability by modeling component-to-rack/server lineage in DocumentDB, enabling inventory forecasting, rapid recall workflows, and asset-location tracking across 8 globally distributed facilities.
- Delivered a fault-tolerant processing layer for hundreds of millions of daily events by orchestrating Lambda, SQS, S3, and DynamoDB in an event-driven pattern, decoupling ingestion from downstream processing at a global scale.
Software Development Engineer-II
Amazon.com
- Owned the Supplier Central Platform, a multi-tenant gateway hosting 75+ internal supply chain applications for global teams and external suppliers, processing millions of daily requests.
- Migrated Supplier Central from private infrastructure to native AWS in under 2 months with zero downtime, keeping all 20+ dependent applications running throughout the transition.
- Stepped into a lead role on a US-to-India project migration, running OP1 planning, sprint ceremonies, and technical reviews while mentoring 2 interns and coaching junior engineers.
- Delivered the Compliance and Sustainability Platform from scratch, replacing manual file-based reviews with automated ingestion of supplier data, utility bills, and regulatory submissions against RoHS, REACH, and Amazon sustainability standards.
- Automated compliance evaluation using Drools business rules, Amazon Bedrock, and Textract for unstructured document processing, with historical trend dashboards and manual review gates for flagged events.
- Eliminated 4,000+ hours of manual compliance review per quarter across 200 global facilities, scaling to millions of devices without additional PM headcount and establishing a verified audit trail for Amazon's Climate Pledge goals.
Software Development Engineer-II
Cisco
- Engineered time synchronization features for Cisco NCS-5500 and 5000 series network backhaul routers using PTP, Sync-E, BITS, and GNSS, achieving nanosecond-level accuracy for 5G network infrastructure.
- Built 3rd-party hardware integration for time sync protocols across Cisco CFPs, SFPs, and external vendor equipment using C-based firmware and API integration.
- Built an in-house time sync testing solution at a hackathon, eliminating dependence on third-party device licensing and saving hundreds of thousands of dollars in testing infrastructure costs.
- Served as single-threaded owner for back-end development on the Shelf Virtualization Orchestrator (SVO), taking sole accountability for delivering configuration support for 2 Cisco product lines from MVP to production.
- Reduced manual network configuration time by hundreds of hours per deployment cycle by integrating the SVO application across multiple Cisco router platforms.
Software Development Engineer
Teradata
- Joined as an intern, earned a full-time offer, and became Single Threaded Owner for the Teradata Unity recovery system, taking sole delivery accountability on a US-to-India project migration.
- Delivered session-level recovery for Teradata Unity, enabling clients to selectively sync sessions and unblock previously unresolvable sync failures, making recovery possible in situations where full-system sync had stalled.
- Resolved critical on-call incidents for Fortune 500 clients, recovering petabyte-scale distributed Teradata warehouses in coordination with client site engineers across active, multi-site deployments.
Experience
Compliance and Sustainability Platform
• Designed and delivered end-to-end: data ingestion from Excel files and utility bills using Amazon Bedrock and Textract, Drools-based business rule evaluation, secure storage in S3 and DynamoDB, and historical trend dashboards with manual review gates for flagged events.
• Eliminated 4,000+ hours of manual review per quarter, scaled to millions of devices without additional PM headcount, and established a verified audit trail for Amazon's Climate Pledge goals.
Manufacturing Execution System (MES) - Infrastructure Supply Chain
• Designed and built the event-driven ingestion pipeline, live operational views, and component traceability layer using AWS Lambda, SQS, DocumentDB, and OpenSearch.
• Delivers sub-second search across 2TB+ of manufacturing data, tracks component-to-device lineage for inventory forecasting and recall, and surfaces on-time delivery performance against data center commitments.
Questive – AI-powered Goal Tracking App
https://github.com/btalloju/goal-tracker• Built solo using Next.js 14, PostgreSQL, Prisma, NextAuth.js, and Google Gemini for milestone generation and daily task ranking. Deployed to production on Vercel with a Neon serverless back-end and Shadcn UI component layer.
Supplier Central Platform
• Owned the platform as a senior engineer, migrating it from private infrastructure to native AWS in under 2 months with zero downtime while building and maintaining core authentication, multi-tenant routing, and user-to-supplier mapping services.
Teradata Unity — Session-level Recovery
• Served as single threaded owner, designing and delivering the feature end-to-end. Enabled clients to selectively sync individual sessions independently of the broader dataset, unblocking stuck recovery scenarios for Fortune 500 clients running petabyte-scale distributed data warehouses.
Time Sync Testing Solution
• Implemented in C with driver-level programming to interface directly with network hardware. Saved hundreds of thousands of dollars in third-party device licensing costs.
