Job Title: Backend Engineer — Production Migration, Security Hardening & Ongoing Maintenance Location - Bangalore About the Engagement: NxtCurve Intelligence is an early-stage, AI-native workforce intelligence startup based in HSR Layout, Bangalore, building Skill Pramaan (blue/grey-collar verified skill passport, live pilot with 1000+ onboarding employees) and MySiGiL (white-collar skill passport with an AI-driven capability taxonomy). Our current codebase was prototyped on an AI powered coding workspace and now needs to move to a production-grade environment capable of supporting national, and eventually global, scale. Scope of Work: Phase 1 — Migration & Understanding (one-time) Review and fully understand the existing platform-based codebase across our product suite Design and execute migration to a production hosting environment outside this (AWS/GCP/Azure — your recommendation, with rationale) Re-architect any Ai platform-specific dependencies that won't hold up outside that environment Phase 2 — Hardening & Testing (one-time) Comprehensive testing: functional, load, and security testing before go-live Harden the application for enterprise-grade security — authentication, data protection, secure API design, credential management Build for durability and reliability at scale — this platform will eventually serve government/PSU clients (we're in active discussions with Karnataka and other state bodies) and international workers, so security and uptime standards need to reflect that from day one Phase 3 — Ongoing Monthly Retainer Monthly troubleshooting and incident response Continued feature development as the product evolves Proactive monitoring, patching, and security maintenance Should scale with us as we move from single-state pilot to multi-state and international deployment What We're Looking For: Strong production backend experience — not just prototyping; someone who's taken a system from "it works" to "it's live and load-bearing" Hands-on experience with cloud infrastructure (AWS/GCP/Azure), containerization, and CI/CD Security-first mindset — comfortable with authentication, encryption, secure credential handling, and the basics of building something audit-ready Python backend fundamentals (FastAPI or equivalent); familiarity with LLM/RAG-based systems is a strong plus given our stack Startup mindset: independent, communicates clearly, comfortable owning a system end-to-end with a small founding team Based in Bangalore strongly preferred - periodic in-person syncs expected, especially during the migration phase Engagement Type: Freelance/contract — Phase 1-2 scoped as a fixed-timeline project; Phase 3 as an ongoing monthly retainer based on performance and fit. To Apply: Share experience with production migrations, security hardening, and any relevant infrastructure/DevOps work. GitHub or portfolio links appreciated.

Hi, I will migrate your FastAPI based AI platform to a production AWS environment and harden it for audit ready security. I can work within your posted USD 250 to 750 budget for the initial phases. I migrated a FastAPI plus RAG prototype to AWS EKS with Terraform and GitHub Actions, supporting 10k daily requests and implementing IAM, Secrets Manager, and automated backups. My approach is to review the repo to map service boundaries and AI dependencies, re-architect model hosting and vector store access onto managed services, containerize and harden each service, implement CI CD and blue green deployments, and add enterprise-grade controls for authentication, encryption at rest and in transit, credential management and logging/monitoring. If you grant read access to the repo I will deliver a written migration plan and a prioritized list of security and uptime blockers within 48 hours, free and no commitment. Can you grant read access to the repo for that audit? Happy to jump on a quick chat. Ali Zain

Your platform will fail a government security audit if you migrate without implementing proper IAM policies, encryption at rest, and audit logging from day one. Karnataka PSU clients will require SOC2-equivalent controls before signing contracts. Quick questions - are you currently handling PII/Aadhaar data that requires localized storage compliance? And what's your target RPS once you scale beyond the current 1000-user pilot? Here is the architectural approach: - AZURE MIGRATION: Lift existing FastAPI services into Azure Container Apps with managed PostgreSQL, implement Azure Key Vault for credential management, and set up Application Insights for real-time monitoring across multi-state deployments. - SECURITY HARDENING: Build OAuth2 + JWT authentication layer, enable field-level encryption for worker PII, configure Azure Private Link to isolate database traffic, and implement rate limiting to prevent API abuse during public rollouts. - CI/CD + DEVOPS: Set up GitHub Actions pipelines with automated security scanning (Snyk/Trivy), blue-green deployment strategy for zero-downtime releases, and Terraform IaC so your infrastructure scales predictably as you expand to new states. I've migrated 4 AI platforms from prototype environments to production infrastructure supporting 50K+ concurrent users under strict compliance requirements. Let's schedule a 20-minute call to review your current architecture before you commit to a migration path.

Hi, this is exactly the transition I help startups make—from an AI-generated prototype to a secure, production-grade platform. I've led migrations to AWS/GCP, implemented Docker, Kubernetes, Terraform, CI/CD, FastAPI, PostgreSQL, secure IAM, secret management, monitoring, and enterprise-grade security hardening for scalable SaaS products. I'll first audit the existing codebase, eliminate platform-specific dependencies, then build a reliable deployment pipeline with comprehensive testing and monitoring. I recommend $6,000–9,000 for Phases 1–2 over 5–7 weeks, followed by a $1,000–1,500/month retainer for ongoing support and feature development.

I understand you're migrating your AI platform to a production-grade environment and need robust security. My experience with migrating complex systems and implementing hardened security measures for AI-driven applications, similar to the requirements for your Skill Pramaan and MySiGiL platforms, directly aligns with your needs. My approach will involve a phased migration leveraging infrastructure-as-code (IaC) with Terraform for reproducible environments. I'll implement containerization using Docker and orchestrate with Kubernetes for scalability and resilience. Security hardening will focus on principle of least privilege, secure API gateway integration, data encryption at rest and in transit, and comprehensive logging and monitoring with Prometheus and Grafana. We'll establish CI/CD pipelines with GitLab CI for automated testing and deployment. To ensure optimal results, could you elaborate on your current CI/CD tooling and any specific compliance requirements you anticipate? I'm eager to discuss how my technical expertise can help secure and scale your AI platform.

Hi, this is squarely my background: PhD in AI and ~two decades in software, including a stint as CTO of an AI startup, so I've taken systems from "it works" to "live and load-bearing." Moving Skill Pramaan and MySiGiL off a prototyping workspace onto production cloud is exactly the kind of migration I handle end to end. Approach: review the current codebase, then migrate to AWS/GCP/Azure (I'll recommend with rationale) with containerization and CI/CD, re-architecting any platform-specific dependencies. Then functional/load/security testing, plus hardening — auth, encryption, secure API design, credential management — to an audit-ready standard suitable for PSU/government clients. Comfortable with FastAPI and LLM/RAG stacks, and available for the ongoing retainer. Could you share the current stack and hosting? I work remotely and can join periodic syncs. Happy to send relevant portfolio links.
