Senior Software Engineer specializing in front-end and full-stack web applications

Gurugram, India6y exp

“Started in a small startup environment and grew from frontend into full-stack ownership across mobile apps, web apps, APIs, backend, and production responsibilities. Strongest in JavaScript/TypeScript and React, with notable experience building an insurance "resume the journey" feature using MongoDB to persist multi-step form progress.”

“Built and owned an internal AI-powered knowledge assistant that centralized fragmented company knowledge across docs, tickets, and internal systems. They designed the backend, ingestion pipelines, vector search, RAG workflow, and APIs, then drove adoption through pilot testing and quality improvements—ultimately automating roughly 30% of support inquiries and cutting resolution time by about two hours per ticket.”

“Built an AI Image Editor end to end with a React frontend and Flask/PyTorch backend, focusing on the hard operational problems of deploying generative AI reliably across CUDA, Apple MPS, and CPU environments. Particularly strong in backend systems, API design, model lifecycle management, and architectural refactoring that improves reliability and future development speed.”

“Frontend engineer who led an internal React + TypeScript admin dashboard end-to-end, including a collaboratively owned component system and complex RBAC/permissions workflows. Emphasizes scalable architecture and correctness using React Query (mutations + query invalidation), centralized permission logic, and TypeScript for safe evolution, plus performance tuning for data-heavy tables and pragmatic MVP-driven delivery with gradual rollouts.”

“Frontend team lead who delivered an ArcMap React + TypeScript product end-to-end, emphasizing Atomic Design-based design systems, reusable component architecture, and performance optimizations (code-splitting/lazy loading, server-side fetching, webpack). Adopted React Query over Redux with centralized query-key management and coached the team on its usage while shipping quickly in a high-velocity environment.”

“Product-minded full-stack engineer with hospitality tech experience who owned and scaled a multi-region guest verification/check-in workflow (ID/passport scanning, OCR, and government submissions) and built internal tools that cut manual entry up to 80%. Also built a React/TypeScript + FastAPI RAG “second brain” with async ingestion workers and an event-driven e-folio email microservice hardened with idempotency and retries.”

“Backend/DevOps-leaning engineer who has owned a Python serverless platform on AWS (Lambda, DynamoDB, Step Functions), including complex multi-step business workflows with transaction-based consistency and robust failure handling. Also supported an on-prem SQL to Azure Data Lake migration by building and monitoring Python + Azure Data Factory ETL pipelines, and led GitOps-style CI/CD automation with GitHub Actions (tests, security scans, automated deployments).”

Junior Full-Stack Software Engineer specializing in GenAI and web platforms

Atlanta, GA2y exp

“AI/software engineer with hands-on experience deploying an LLM-powered quiz generation platform for students, integrating Python services with Gemini APIs plus frontend and database components. Emphasizes production-grade reliability through observability, schema validation, async processing, and performance tuning under high concurrency, and has collaborated with product/operators (e.g., at Colombo AI) to translate real-world constraints into scalable technical solutions.”

Junior Software Engineer specializing in distributed systems and cloud platforms

2y exp

“Software engineer (Lance Soft Engineering) who built a Java/gRPC real-time request tracking system supporting ~20K simultaneous requests, using Kafka event streaming and PostgreSQL to improve transparency and cut support requests by 35%. Demonstrates strong production operations skills—resolved live latency spikes with Kafka async messaging (+48% throughput) and executed safe migrations using parallel runs, staging validation, and blue-green deployments.”

Lindsey Nettles

Senior Digital Marketing & Operations Specialist in lifecycle marketing and analytics

West Hollywood, CA15y exp

“Marketing Director-level CRM/lifecycle marketer with deep restaurant/franchise and DTC experience, known for using CDP-driven segmentation and local-store personalization to materially lift loyalty (18% to 30%) and shift visit frequency (60% monthly-to-weekly). Comfortable integrating data across POS/CRM/email/feedback systems via APIs and running continuous A/B testing, plus strong stakeholder management to win franchisor buy-in through pilots and measurable outcomes.”

“Full-stack engineer who built WordCon, an AI-powered vocabulary learning platform, end-to-end across React/Next.js, Python, AWS, and GenAI services. Particularly strong at turning ambiguous AI product ideas into structured, scalable systems by combining deterministic learning logic with LLM-powered personalization, and has additional experience modernizing legacy PHP systems into React/Node architectures.”

“Frontend-focused engineer with experience building internal editorial tools at Healthcentral using React, TypeScript, Redux Toolkit, Node.js, and MongoDB. Stands out for simplifying complex CMS workflows and solving real production performance issues, including a JW Player migration optimized with a facade-based lazy-loading approach.”

“Unity developer with shipped Meta Quest experience who owned the full lifecycle from architecture and feature development through builds and store compliance. Demonstrated strong performance optimization skills (profiling in Unity and MQDH, optimizing textures and render layering) and has built and shipped a modular, cross-platform puzzle game (PC/web/mobile).”

“BI developer and software engineer with experience spanning pre-funding startup work and production web applications. They built database/reporting foundations for an early-stage venture, later developed an AI-assisted regression testing tool in Python/Selenium, and worked on JavaScript dashboards plus bidirectional API integrations in ASP.NET Core systems.”

Mid-level Full-Stack Software Engineer specializing in AI-augmented web and mobile systems

Chicago, IL4y exp

“Builder-oriented engineer who has shipped production systems across fintech-style payments, mental health recommendations, industrial oil-and-gas analytics, and AI-assisted client discovery. Stands out for combining deep backend reliability practices with founder-facing product scoping, and reports using Claude-based internal tooling to increase delivery capacity by 40% and handle eight concurrent projects.”

“Full-stack product engineer with hands-on ownership of both real-time product infrastructure and production AI systems. They shipped a notification platform that materially improved engagement and repeat purchases, and also built key layers of an AI support agent with strong reliability controls and user-centered UX improvements that boosted adoption.”

“Full-stack engineer with experience building a NASA-funded simulation management platform using React, TypeScript, Next.js, PostgreSQL, AWS, and Docker. Stands out for owning complex, long-running workflow features end to end in production and driving measurable performance improvements, including a 40% database load reduction and API latency improvements from roughly 500ms to under 200ms through Redis caching and async architecture.”

“Full-stack engineer with experience building healthcare scheduling, telehealth, reimbursement, and agent workflow systems using React, Node.js, MySQL, TypeScript, and GraphQL. Stands out for combining hands-on product design in ambiguous environments with measurable technical impact, including a 40% performance improvement and reduced LLM costs through batching and backend optimization. Also brings manufacturing/MES experience and a strong habit of reshaping products based on direct user feedback.”

“VR multiplayer Unity developer who implemented high-impact interaction systems (notably a math-driven, physics-aware door system with audio occlusion and culling) and designed/built a fully custom cross-platform multiplayer stack from scratch using KCP, WebSockets, WebRTC, and MemoryPack—plus recording, NPC support, and backward-compatible client modes for an educational/learning platform.”

“Infrastructure engineer focused on AWS platform automation: built a full CloudFormation-based environment (networking, Aurora, ElastiCache) and created Python tooling plus Lambda-backed custom resources to automate deployments, user provisioning (MySQL/RabbitMQ), and operational workflows.
