Instahyre

Software Development Engineer II

Jan 2025 – Jan 2026Remote, India
  • Full-stack development: Built employer-facing recruitment features using Angular + Django, including candidate screening modules (activities, notes, interview scheduling, evaluations). Architected Angular component structure for unified candidate sidebar view integrating 5+ modules with responsive UI and Django REST API integration.
  • Backend performance: Led company-wide Django-to-Jinja migration across 40+ modules; reduced page load from ~1000ms to <200ms (5x improvement). Optimized critical APIs via SQL query rewriting (N+1 elimination, index additions, complex join rewrites), Celery/Redis async offloading, and caching — reduced API response times by 40-60%.
  • System design: Architected unified candidate view backend integrating 5+ microservices with efficient data aggregation and low-latency queries (<50ms avg); built Elasticsearch-based resume screening pipeline for candidate matching.
  • Mentored SDE-1 engineers on async patterns, DB optimization, and API design; led production incident response using Datadog, Sentry, and Logz.io.

Cloudify

Business Integration Specialist

Aug 2024 – Dec 2024Remote, India
  • Full-stack development: Built and deployed Django/Express backends with React/Next.js + TypeScript frontends on AWS Serverless (Lambda, SST) and Azure; managed VMs, load balancers, PostgreSQL RDS/Azure Database instances.
  • Delivered production-grade 3rd-party integrations: Amazon SES (retry logic, bounce handling), MSG91 (WhatsApp/SMS, high-volume queue management), Stripe (payments, webhooks, PCI compliance), Celery/Redis (distributed async queues), Shopify/WooCommerce (inventory sync, order webhooks).
  • Set up CI/CD pipelines (GitHub Actions, GitLab CI), automated deployments, DB backups, and monitoring (CloudWatch, Azure Monitor); maintained 99.5%+ uptime.

Saara Inc

Lead Software Developer

May 2022 – Aug 2024Remote, India
  • AI product development: Led SalesGPT — production AI sales assistant for e-commerce merchants built on OpenAI GPT-3.5/GPT-4; owned full lifecycle from product discussions through UI/UX design, backend architecture, and Azure deployment. Built interactive React chatbot UI with real-time messaging and dynamic product recommendations.
  • LLM integration: Implemented prompt engineering (system prompts, few-shot examples, context management), rate limiting, and cost optimisation via request throttling, query caching, and batch processing — reduced OpenAI API costs by 40%. Built retry logic with exponential backoff and graceful degradation for production reliability.
  • Async AI pipeline: Offloaded LLM inference from the request cycle using Celery/Redis tasks; built ETL pipeline ingesting product catalogs (Shopify/WooCommerce APIs), user sessions, and conversation history into PostgreSQL for fast retrieval in AI context windows.
  • Set up custom Datadog metrics for AI response quality (latency, token usage, error rates); A/B tested prompt variants to improve recommendation accuracy.

SHL

Software Engineer — Reporting & Scoring

Jul 2020 – May 2022Remote, India
  • Core backend developer on Reporting and Scoring platform (PHP/Symfony-based custom framework): Developed REST APIs, managed databases, and built candidate assessment report generation pipelines. Led final milestone migration of SHL evaluation logic into Aspiring Minds' modules post-acquisition, combining best-of-breed scoring algorithms from both platforms.
