Sanjay D.

I build and ship production web applications end-to-end: TypeScript across the stack, React/Next.js frontends, Node/NestJS APIs, PostgreSQL with Prisma, and AWS infrastructure that I design, deploy, and maintain myself (Terraform - ECS Fargate, RDS, ALB, CodePipeline, VPC networking). Recent work includes a security/threat-intelligence platform I architected on AWS — multi-service backend, data pipelines processing domain-scan feeds, MITRE ATT&CK-mapped schema, CI/CD from Bitbucket to ECS. I've also built and delivered SaaS MVPs for startup founders (see reviews below) and long-term product work spanning 395+ hours with a single client. Where I'm most useful: • Building a SaaS product or MVP from zero to deployed — frontend, API, database, cloud, CI/CD • Adding AI/LLM features to existing products — API integrations, structured outputs, data pipelines • AWS work: architecture, cost optimization (I've cut infra bills by rethinking networking), deployments, managing with terraform . • Rescuing or extending an existing TypeScript/Node codebase in production I work with a security mindset — I've built threat-intelligence tooling and design systems with auth, data isolation, and compliance in mind, which matters if you're in education , fintech, healthcare or handling user data. Fluent English, comfortable with daily standups and US-overlap hours (IST evenings = US mornings). I own features end-to-end and communicate clearly in writing — you'll always know where things stand.
