Prakhar Varshney — AI systems engineer
From interfaces to distributed systems to multi-agent orchestration—I turn ambiguous, human workflows into reliable software that moves at machine speed.
The route
Places changed the scale of the problems I could see. Drag the globe or choose a stop to follow the shift—from learning how software works to designing systems that coordinate intelligence.
Where curiosity became craft.
Delhi is both the origin and the foundation: taking things apart, asking better questions, then turning that curiosity into a computer-science education and a bias toward shipping.
How I think now
The hard part of agentic software is not the demo. It is designing roles, memory, guardrails, evaluation, and fallbacks so the whole system remains useful under pressure. Explore the operating system below.
Version history
My career is less a ladder than a widening lens: from “can I build this?” to “should this exist, can it scale, and can people trust it?”
Operating range
I work across the stack because agentic products rarely fail in only one layer. My sharpest edge is connecting model behavior, distributed infrastructure, product experience, and measurable outcomes.

Senior Software Engineer · Singapore
Built the agent harnessEngineered the production runtime behind an autonomous sourcing team: specialized agents, Zod-validated tool contracts, shared workflow state, checkpointed execution, retries, fallbacks, and human escalation across Gemini, OpenAI, and Anthropic.
Made quality measurableBuilt reliability loops around every stage with constraint and schema validation, evidence-grounded outputs, hallucination checks, confidence gates, regression evals, and model-based scoring—sustaining 95%+ spec accuracy across 1,200+ monthly requests.
Optimized every tokenReduced AI cost and latency through task-aware model routing, context compaction, token budgets, caching, batching, parallel fan-out, and early exits—reaching 100+ specs per minute and 70% faster turnaround.
Productionized the intelligenceRan the system on AWS Lambda, Step Functions, SQS, CDK, Python, TypeScript, and PostgreSQL with per-run traces, cost/latency telemetry, replayable jobs, and recovery paths powering AutoQuotation, supplier ranking, and product mapping.
Senior Software Engineer · Boston
Automated complianceLaunched VacTrack, an AI vaccination-compliance platform that reduced Student Health Services workload by approximately 60%.
Scaled document intelligenceArchitected a horizontally scalable document pipeline capable of processing 1,000 documents per minute with Python, Docker, and AWS.
Returned time to physiciansPioneered multi-channel patient engagement across SMS, email, phone, and WhatsApp, saving physicians an average of three hours daily.
Software Engineer · India
Modernized operationsLed admin-platform delivery and deployments across Django, Vue, Kubernetes, Docker, and S3, raising marketing throughput by 30%.
Accelerated paymentsBuilt an event-sourced Kafka payment service that made client-side payments 65% faster.
Moved work off the request pathImplemented offline synchronization and invoice queues with Django Channels, Celery, and pyPDF—improving speed by 18% and cutting server cost by 21%.

The human in the loop
Crossing cities, domains, and systems taught me that engineering is a social act. The best architecture begins with listening; the best automation preserves human judgment; and the best teams make room for dissent, ownership, and a little wonder.
