A simple ambition: 10 LPA
I entered college with one clear ambition: earn a 10 LPA offer after graduation. It gave me a starting point, even though I had no idea how far the goal would eventually move.

The offer rose from 8 to 28 LPA. I declined because university rules could close later campus opportunities.
I joined with two Team Amigos friends and helped hire teachers, shape the course, and build the early learning platform.
Amazon came to LPU for interns. I became the first student selected directly for a full-time role, advertised by the university as 32 LPA.
I started coding before fully understanding the question and was not selected. The experience taught me to listen, clarify the problem, and only then solve it.
When my Scaler teammates left for internships, I returned to college and helped juniors and Programming Pathshala students prepare for placements.
With Amazon starting in July, HackerEarth became a six-month final-semester bridge into full-time engineering.
Competitive programming gave me a steady supply of difficult problems. The rankings mattered, but the lasting value was learning to stay with a challenge until I understood it.

A difficult question is not automatically a useful one. Clear wording, sensible limits, and complete tests shape every candidate’s chance to succeed.
At HackerEarth, difficulty alone was never the goal. Every problem had to challenge candidates while remaining clear, consistent, and focused on the skill it was intended to measure.
Each problem needed clear wording, sound constraints, a correct solution, and thorough tests. The assessment had to measure skill consistently and give every candidate a fair opportunity to demonstrate what they knew.
Creating problems pushed me to explore edge cases, design challenging variations, anticipate different approaches, and test solutions from a candidate’s perspective. Explaining these ideas further strengthened my knowledge.
Curated and tested algorithmic problems for hiring and internal coding contests conducted for Google, Facebook, Nokia, PayPal, Salesforce, and Infosys, including the nationwide HackWithInfy contest with 167,000+ participants.
Helped increase Nokia’s post-contest Net Promoter Score from 7 to 8 by strengthening problem quality, promptly addressing participant queries and accelerated issue resolution.

I worked on finance systems handling more than 100,000 invoice requests a day. The goal was simple: protect money, surface problems sooner, and keep every release dependable.
A small mistake could delay a payment or hide a costly invoice problem. Good work meant understanding the full customer need, releasing carefully, watching results, and responding quickly when something failed.
I built three checks for unusual, duplicate, and potentially fraudulent invoices. They identified more than $100M in anomalies within one month.
I helped reduce the wait for anomaly reports from 24 hours to near real time, so finance teams could act sooner.
I added service interfaces, dashboards, alerts, automated infrastructure, and release checks so the benefit could continue safely after launch.
Built statistical and ML-powered systems in Amazon Finance Automation to detect invoice fraud, duplicates, and anomalies at scale.
Built duplicate and anomaly-detection capabilities for invoice creation and update workflows handling 1 lakh+ requests every day across Amazon’s retail, non-retail, and corporate finance systems.
Implemented 3 anomaly-detection rules using statistical analysis and machine learning, including Isolation Forest. The rules identified over 100M USD in anomalies within the first month.
Reduced anomaly reporting latency from 24 hours to approximately 5 minutes through Gandalf-Veritas integration, giving finance teams near-real-time visibility into suspicious activity.
Built APIs and operational dashboards for monitoring and alerting, and used AWS CDK to provision infrastructure and CI/CD pipelines across multiple services.
Developed microservices using Java, Kotlin, TypeScript, Python, Elasticsearch, DynamoDB, Coral, Smithy, and AWS.

“I had the opportunity to work closely with Sanjay during the early stage of our career, and even though we worked together for just about a year, his impact was clearly visible. He quickly developed strong product knowledge and was able to get a deep understanding of multiple services in a short time, something that usually takes much longer. It was impressive to see him already making an impact at the next level, driving discussions, and contributing meaningfully across teams. What stands out most about Sanjay is his leadership quality and the way he connects with people. He's transparent, approachable, and always willing to help others, whether it's providing technical guidance, or simply supporting teammates when needed. He's someone who not only gets the job done but also uplifts those around him. A great colleague to work with, and someone who is continuously learning from everyone while being open to sharing his own knowledge. I've learned a lot from him in a short span of time, and it's been a real pleasure working together.”

Search work began with a simple question: what is this person trying to do? Language, local context, and careful releases all followed from that.
At Google, I learned to begin by listening, clarifying the need, and understanding the people affected. That approach guided both product decisions and work across several teams.
I built education features and helped Search better understand what people wanted from exam-related questions. The change reached 0.05% of Search traffic—an estimated 1M+ daily queries.
I helped launch exam results in Hindi, Tamil, and Telugu, then built a common service so several features could reuse the same support.
Progress depended on clear requirements, shared priorities, patient discussion, and careful changes across several teams.
Across 50+ Bosscoder sessions, I supported engineers who later joined Atlassian, Adobe, Amazon, PhonePe, and Microsoft.
As part of Google’s Search India Team, built exam OSRPs and the interactive Exam Quiz, reaching 100M+ educational users on a product serving 1B+ queries per day.
Migrated Google Search’s serving query-understanding architecture from entity-driven to intent-driven through the diOSRP Migration, enabling better Organized Search Result Pages (OSRPs) that answered user intent directly instead of routing users to the traditional 10 blue links; impacted 0.05% of Search traffic.
Launched localized Exam OSRPs in Hindi, Tamil, and Telugu, adding exam dates, fees and waivers, tabbed result layouts, and the Periodic Table. Localization reached 0.03% of Search queries and 0.0019% of educational queries, improving accessibility; also designed a scalable Language API for Indic locales.
Contributed across Google Search’s monorepo, one of the world’s largest codebases with 2B+ lines of code and 10M+ files, using C++, Java, Python, Go, gRPC, Protocol Buffers, Knowledge Graphs, and other internal technologies.
Collaborated across Search teams to resolve production issues, align requirements, and prioritize high-impact improvements.
Contributed to Google Bard’s early model-improvement journey by training and evaluating LLM responses, helping improve output quality as the technology evolved from unreliable early behavior toward practical usefulness.

Growing systems and people
Apr 2024 — Present · Oracle Health · Remote
Tech Lead since Oct 2025
I now lead work across design, delivery, hiring, and team growth for a healthcare reporting product where reliability directly affects people’s work.
Oracle Health offered meaningful problems, room to lead, and a flexible working model. The role grew from building software to helping a team deliver it well.
I guide the reporting product across requests, templates, data, final documents, security, history, and recovery when work fails.
For very large reports, the team cut memory use by 40%, improved speed by more than 25%, and reduced repeated data work by 60%.
I built the India team, led four quarterly releases, partnered with 25+ teams, and helped make 25+ hires while keeping the product from depending on one person.
Technical Lead for Oracle Health’s Clinical Reporting / Output Management team, owning the architecture, technical direction, delivery, and production readiness across 3 products: MRO Gen2, XR Gen1, and Dex Gen1.
Built 7+ Java Micronaut microservices from 0 to 1, transforming a medical-record output platform into a modular Gen2 reporting system spanning APIs, template management, data extraction, report generation, and the mro-ai-intelligence-service. Proposed modern AI capabilities, including an advanced AI-powered template builder, shaped the product roadmap, and aligned execution with product managers and partner teams.
Scaled the platform to handle 1M+ requests per day while keeping p90 latency under 30 seconds. For the roughly 1% of complex reports that take more than 10 minutes, and sometimes hours, introduced asynchronous fast and slow lanes with bulk generation, retries, DLQs, idempotency, horizontal scaling, security, dashboards, and alerting.
Led product delivery across 4 quarterly releases, from roadmap planning and architecture through production launch. Broke down work for 5 to 8 engineers, removed blockers, and drove architecture decisions, defect resolution, compliance, monitoring, and operational readiness.
Served as a primary escalation owner for critical production issues, leading high-severity investigations through diagnosis, remediation, and prevention. In one example, brought approximately 1,000-page reports back within the 30-second SLA, reducing heap usage by 40%, improving performance by over 25%, and driving request-level caching that cut data-extraction time by 60%.
Partnered with 25+ cross-functional teams to turn custom clinical-reporting needs into reusable platform capabilities. Cut Gen2 onboarding from 2 weeks to under 1 week, a reduction of more than 50%.
Led a project involving 3 engineers to deliver Gen1 Report Ingress and 6 APIs in 1 quarter + 1 month versus 2 quarters planned; enabled WebSphere-to-EJS migration with better performance, stability, scalability, and lower third-party cost.
Took ownership of highly ambiguous technical and product scopes, turning open questions into clear architecture and execution plans across multiple initiatives, including early-stage planning for the SI DRZ region build and EHRC modernization program.
Built and led the India Clinical Reporting team from scratch, growing the leadership scope to 10+ engineers across 3+ products. Strengthened organization-wide hiring as a Senior Key Interviewer (Bar Raiser), conducting 100+ interviews and contributing to 25+ hires; also mentored and judged 12 teams developing AI projects at Oracle-wide OraHacks hackathons.
