Vijay Khot
Backend & ML Infrastructure Engineer for the Built World
I spent over 7 years managing construction projects before earning my Master’s in Computer Science. Now I build backend systems and ML tools for the built world, from forecasting engines to permit workflows and payment systems.
My core stack is Python (FastAPI), Node.js (Fastify), AWS, and Docker. I turn messy, real-world workflows into reliable APIs and data pipelines.
Backend & APIs
RESTful services with solid data modeling and caching.
ML in Production
Dockerized inference engines with Redis and CI/CD.
Construction-Aware
Encoding real-world permit/material workflows into software.
Professional Experience
Backend Software Developer (Volunteer)
Oct 2025 - PresentActing as Technical Lead, I rescued legacy infrastructure by recovering domains and migrating DNS. I architected a zero-cost serverless donation platform using Netlify Functions. To unblock Google and Stripe verification, I engineered a critical email workaround, implemented SPF/DKIM security, and led MVP scope negotiations.
Software Developer (Volunteer)
Aug 2025 - PresentI architected a decoupled donation pipeline from WordPress to Salesforce using Platform Events and custom PHP middleware. This cut costs by migrating integrations from Zapier to Make.com. I also led recovery efforts for critical production issues like database migration failures and Cloudflare WAF blocks, while advising leadership on secure data strategies.
Project Engineer
May 2017 - June 2023I orchestrated a $3M+ government housing initiative that enabled 605 families to build homes. I managed the full lifecycle from proposals and permits to fund distribution while leading cross-functional teams. I also modernized reporting by building Python (Pandas) workflows to replace manual tracking.

Permit Workflow Service
A focused backend for construction permitting applications and compliance: deterministic rule engine, guarded state machine, and async PDF packet generation.
My Role:Designed and implemented a layered service (API/Domain/Data) with a deterministic rule engine, guarded state transitions, Prisma-backed persistence, and BullMQ worker for Puppeteer-based PDF packet generation. Added Prometheus-compatible metrics, Swagger docs, and secure x-api-key preValidation. Provided Docker setups and seed data for local development.
Material Forecasting Engine
Time-series forecasting service for materials: historical series storage plus model-based forecasts and cached responses.
What I built:Built a FastAPI backend with Redis caching, Alembic migrations, and a Next.js App Router frontend. Implemented Docker + docker-compose for local dev, CI with GitHub Actions, and deployments to Heroku, Vercel, and an AWS ECS pipeline (ECR/ALB/ECS). Resolved DB, Alembic and build-time environment issues during production deploys.
Email Outreach Platform
A robust full-stack platform for personalized email campaigns, contact management, and template-driven outreach. Built for efficiency, scalability, and real-world deliverability.
What I built:Led end-to-end development: architected RESTful APIs, designed service layer, implemented Prisma transactions, and solved critical email deliverability issues (SPF, DKIM, DMARC, AWS SES). Integrated rich text editor, live preview, dynamic placeholders, and campaign management. Migrated email infrastructure for sender reputation and production readiness.
