Software Development Engineer II (SDE-2) | Backend โข System Design โข Infrastructure โข Enterprise Applications
I build backend systems, scalable architectures, and infrastructure for enterprise applications in commodities fintech (CTRM โ Commodity Trading & Risk Management).
I'm particularly interested in how systems behave beyond the happy path โ scalability, reliability, multi-tenancy, data consistency, APIs, distributed systems, performance, and clean architecture.
I'm also a curious engineer who enjoys exploring new technologies โ from AI agents and LLM integrations to CRM platforms, quantitative/derivatives pricing systems, and cloud infrastructure.

Migrating a legacy MATLAB derivatives pricing engine to a Python/FastAPI microservice, targeting 7-significant-figure numerical parity across 17+ derivative product types.
- Reverse-engineered proprietary SciComp MEX binaries with no source access, covering Kirk's Approximation, Bilognormal (BLN) quadrature, Normal Diffusion local vol with Levenberg-Marquardt calibration, Craig-Sneyd ADI splitting, and barrier option pricing
- Replaced the MATLAB batch pipeline with Polars + vectorized NumPy, cutting per-batch compute time by ~83%
- Implemented a Strategy Pattern routing mechanism supporting 15+ derivative models, reducing new-model onboarding from multi-day work to a single registration step
- Diagnosed and fixed production issues: FastAPI event-loop blocking causing pod restarts under batch load, and DataFrame chunking inefficiencies in bulk inserts
- Service processes 1M+ pricing records daily on AWS EC2 with CloudWatch monitoring
Leading a MySQL-to-PostgreSQL migration for a multi-tenant CTRM platform.
- Migration pattern: strip business-unit table suffixes, add
tenant_id/business_unitdiscriminators, replace composite keys with UUID surrogates - Wrote Liquibase changesets, debugged null-returning views across joined master data, and built financial-parameter management APIs with full CRUD, RBAC, and pagination
Built a centralized license and tenant management platform using Angular, Spring Boot, PostgreSQL, and Hibernate.
- JWT authentication and RBAC enforced across 6+ microservices with role-level multi-tenant isolation
- Audit logs and configuration stored on AWS S3
A full-stack CRM built with Angular + FastAPI + Supabase, targeting micro-influencers in India (1Kโ100K followers).
- Core features: shareable collab link, inbound brand-lead form with budget qualifier, kanban-style lead inbox, WhatsApp/email notifications
- Configurable lead-status system with immutable key slugs and safe deactivation flows
- Freemium monetization model (Free / Pro / Agency tiers)

AI Agents + LLM Applications
Things I want to understand deeply rather than just use:
- Distributed systems & event-driven architecture
- Message queues & caching
- Database internals
- High-throughput APIs
- Kubernetes & cloud architecture
- Observability
- AI agent architecture & LLM infrastructure
- Large-scale data processing
Don't just make it work. Understand why it works, how it fails, and how it behaves at scale.
I care about:
Correctness โ Maintainability โ Performance โ Scalability โ Reliability
Good engineering is often less about writing more code and more about making the right architectural decisions before writing the code.
Working toward becoming a stronger backend / systems engineer, with a long-term focus on:
Backend Engineering โ Distributed Systems โ System Design โ Infrastructure โ Architecture
while keeping enough frontend knowledge to understand and build the complete product.
- ๐ณ Cooking and Travelling
- ๐ฑ Following consumer tech and the Indian job market
- ๐๏ธ Building side projects
- ๐ค Experimenting with AI agents
I'm always interested in talking about:
