Lead Software Engineer (Backend)
riskprofiler.ioRiskProfiler Cyber Security
Leading the backend team at RiskProfiler, a cybersecurity startup that helps organizations assess and manage their attack surface and security risk.
- Building scalable APIs and data pipelines in Python, JavaScript and Go - handling 1M+ API requests and 10M+ cloud asset scans every month while ensuring high availability and low error rates.
- Developing serverless and server-based architectures on multiple cloud platforms - AWS, GCP and Cloudflare - while optimizing cloud costs, e.g saved over $2000/month in the past few months without impacting performance.
- Integrating AI agents where useful, such as integrating Google Gemini LLM and RAG to autofill security questionnaires, reducing manual effort by 80%.
- Building and mentoring the backend team - by interviewing candidates, conducting code and design reviews, and setting up best practices for development, deployment and monitoring.

Software Developer (Full-Stack)
ethicalhat.comEthicalHat Cyber Security
Built online platforms that help security professionals assess their attack surface and improve their cyber security. Key projects that I worked on:
-
Serverless platform for discovering security issues
- Used AWS and the Serverless framework to build and deploy Lambda functions and Fargate tasks written in Python, Go, and JavaScript.
- Designed an event-driven architecture using SNS for notifications and implemented a rate-limiting setup using SQS FIFO queues for calling third-party APIs.
- Optimized DynamoDB schemas and indices based on query patterns and used DynamoDB streams to aggregate item counts across multiple categories.
- Created a user management module using Cognito user pools, clients, and authorizers, along with building REST APIs using API Gateway and Lambda.
- Accelerated front-end deployment by 15x using S3 and CloudFront via the Serverless framework, replacing AWS Amplify.
- Automated microservices deployment with a dependency resolution script, that made deployments up to 4x faster.
-
Full-stack application to run security scans
- Designed and implemented the UI using Semantic UI and developed the back-end with Django.
- Built core features, including the integration of multiple security scanners and vulnerability feeds.
- Managed background and periodic tasks using Celery with RabbitMQ.
- Developed a large-scale domain search feature using Elasticsearch to scan 250M+ domains.
- Worked with both relational (PostgreSQL) and non-relational (MongoDB) databases.
-
csat.cisecurity.org
Controls Self-Assessment Tool (CSAT)
Developed for the Center for Internet Security (CIS), USA- Developed the full-stack application, implementing the UI with Semantic UI and the back-end with Django.
- Independently built core features and integrated third-party services like Slack.
- Containerized the web app using Docker and automated service deployment with Docker Compose.
