I am a Senior Software Development Engineer and Software Development Manager-in-training with nearly 10 years of experience at Amazon . My journey began as an intern and evolved into leading the architecture for high-availability, Amazon-scale distributed systems across payments, subscriptions, fraud prevention, compliance, and finance automation . Throughout my career, I've designed cloud-native AWS backend systems, complex API integrations, and event-driven microservices that have driven substantial business impact, such as a $55MM billing recovery system, a $14MM fraud reduction initiative, and a subscription transition platform generating $75-80MM globally

What makes me unique is my hybrid capability as both a hands-on technical architect and a delivery-focused engineering leader . I combine a strong foundation in backend engineering (using Java, Python, Elixir, PostgreSQL, and AWS) with rigorous operational leadership, escalation handling, and team mentorship . Recently, I have also expanded my expertise into AI and ML-adjacent platforms, independently building production-ready AI workflows, LLM intent classification pipelines, and AI-driven CRM integrations using frameworks like Phoenix LiveView and Oban . I do not just write code; I translate complex business ambiguity into scalable execution plans, ensuring that engineering outcomes align perfectly with measurable business value

What I am looking for is a Principal Backend Engineer, Tech Lead, or senior technical leadership role where I can drive large-scale system architecture and lead cross-functional initiatives . I thrive in environments where I can own the end-to-end architecture of high-scale systems, mentor engineering teams, and integrate modern data and AI capabilities to solve complex problems, all while maintaining a high bar for operational excellence, reliability, and customer impact

Employment History

Software Development Engineer II / Transitioning SDM at Amazon 2024 - 2026
SDE II / Transitioning SDM | Pune, Maharashtra, India - Led design and implementation of the Simba Holds Resolution service within Amazon Vendor Payments, enabling FinOps users and vendors to resolve invoice holds by updating invoice line price or quantity directly through FinOps and Vendor Central experiences; contributed roughly $5MM in savings through OFA migration. - Architected an AWS-based asynchronous workflow for the Dispute on Receive compliance program, initially launched in France and Germany, enabling vendors to dispute discrepancies between invoices and warehouse receipts earlier in the acquisition lifecycle and helping Amazon align with EU compliance requirements. - Drove JDK 8 to JDK 17 and 21 migrations across 5+ vendor payment services, delivering 20 to 40 percent higher throughput, substantially faster runtime behavior, modern Java language support, improved TLS posture, and sub-millisecond GC pauses through Generational ZGC. - Built end-to-end automation and integration test suites for domain services and core adjustment services using the internal Lugia framework over TestNG and Hamcrest, strengthening CI/CD adoption and enabling a push-and-forget delivery model with HITL only for sensitive pipelines. - Mentored 2 SDE I engineers and 5 interns, provided design and code review guidance, and partnered closely with PMs, SDMs, and TPMs to keep high-visibility initiatives moving with clear execution and stakeholder alignment.

Software Development Engineer II / Transitioning SDM at Amazon 2021 - 2024
SDE II / Transitioning SDM | Seattle, WA, USA - Led high-level architecture and low-level design for Project Chameleon, a Prime signup fraud prevention initiative that presents proactive challenges based on precomputed risk propensity and behavioral categorization, including enhanced VET, Transition Intent Verification, and Arkose CAPTCHA challenges for payment fraud, identity fraud, and bot traffic. - Partnered across PM, TPM, SDM, and senior engineering stakeholders to estimate, decompose, and deliver the program; owned the most complex modules personally, delegated well-bounded components to SDE I engineers, and mentored them through implementation, resulting in a solution with roughly $14MM in annual worldwide fraud reduction impact. - Helped preserve Prime signup performance by influencing upstream and partner teams on API usage and latency-sensitive integration patterns, ensuring fraud defenses did not materially degrade the end-to-end customer signup journey. - Architected and delivered Prime Billing Problem State Redrive, a native AWS implementation that redrove legitimate Prime customers after successful purchase events on newly added cards, restoring Prime benefits and unlocking approximately $55MM in business impact in North America with broader worldwide applicability. -Worked deeply with event-driven systems using ECS services, SQS and SNS patterns, DynamoDB-backed data flows, and internal workflow engines; mentored 4+ SDE I engineers, evolved into a tenured team lead, and authored high-level and low-level design templates later reused in the Prime payments space.
Software Development Engineer at Amazon 2017 - 2021
SDE I / SDE II | Bangalore, India - Foundational member of the Transition Service, a backend platform enabling any-to-any plan transitions in Amazon's subscription space, beginning with Prime Student to Prime and later extending to marketplace migrations, Teen to Student transitions, and multiple verification and eligibility strategies; the Student to Prime transition space alone drove roughly $35MM to $40MM in the US and $75MM to $80MM worldwide. - Designed core plan transition modules, configuration-driven workflow behavior, and atomic contextual enrichment APIs used to initialize and enrich transition workgraphs; built these systems using Java, Guice, interface segregation, factory-pattern module switching, and externalized configuration through AWS AppConfig to keep workflows extensible and operationally manageable. - Independently led the Germany Student graduation and transition launch, solving for marketplace-specific tenure rules, multiple Prime and Student plans, and Pangaea cross-country marketplace behavior; the launch contributed roughly $4MM in revenue and required strong cross-functional decision-making with limited SDM involvement. - Built CoralRetryMetricsUtils, a lightweight Java library for retry metrics and adaptive backoff strategies that improved downstream- awareness and helped reduce retry storm risk; the library was adopted by 30+ Amazon teams. Promoted to SDE II on March 31, 2019.
SDE Intern at Amazon 2016 - 2016
Developed Student audit, graduation, and reverification workflows that notified students near contract end, presented reverification and appeal experiences, and supported transitions from Student plans to Prime plans. Worked across Java backend services, Orca workflows, Spring MVC controllers, and Freemarker-based user experiences; converted to full-time SDE I based on internship performance.
SDE Intern at Global Logic 2013 - 2013
Gesture rejection using C#: Created a windows application that demonstrates gesture recognition using Kinect, allowing to right and left click, scroll, zoom anything using gestures
