...contributing on day one. You must be comfortable building asynchronous back-ends in FastAPI, have real production experience creating LangChain chains and agents, and be equally at ease working with both OpenAI and Hugging Face models. Day-to-day you’ll design and optimise micro-services that call LLMs, manage embeddings in Pinecone or FAISS, and orchestrate data flows through PostgreSQL, MongoDB and Redis—everything neatly containerised in Docker for local and cloud runs. Expect plenty of room to prototype new AI features, run quick experiments, and then harden the successful ones for scale. The role is 100 % onsite in our Sector-62 Noida office; close collaboration with product and design teams is essential, so remote or hybrid isn’t an option right now. Ke...

... The stack is .NET (C#), PostgreSQL, and Redis; a separate team will handle the React front end, so your focus stays firmly on the APIs, data layer, and real-time processing pipeline. What the engagement looks like You will translate our detection logic into clean, well-tested C# services, design the relational schema in PostgreSQL, and use Redis for low-latency caching and message queues. Because the app is completely standalone, there are no third-party or legacy integrations to worry about—every decision you make will directly shape the core product. Key expectations • Produce readable, documented code that passes automated unit and integration tests. • Keep performance front-of-mind: efficient SQL, sensible indexing, and thoughtful Redis ...

...especially on the homepage, and I want to tackle every layer that affects load time over the next 30 business days. Here is what I expect by the end of the engagement: • Multi-level caching in place (browser, page, and object) configured so pages are served from memory or disk with the fewest possible database calls. You are free to choose the most suitable stack—whether that is a combination of Redis, Varnish, or a premium caching plugin—but it must work cleanly with my current theme and plugins. • Image assets moved to a CDN. I prefer Cloudflare and already have a basic account, so your plan should leverage its image hosting and edge network features. If there is a strong reason to consider an alternative, I am open to hearing it, but Cloudflare should ...

...Anti-scam protection via mandatory TIN/Business license validation and keyword detection. Engagement Tools: Automated daily job digests, smart alerts for matching vacancies, and threaded in-app chat between parties. Monetization: Paid "Featured" and "Boosted" vacancy tiers requiring admin payment approval. 4. Technical Architecture Stack: Python (Aiogram Framework), PostgreSQL Database, and Redis for caching/queuing. Deployment: Optimized for low-resource VPS (1GB RAM, 1 vCPU, Ubuntu). Automation: Cron jobs for hourly job expiration, 6-hour repost cycles, and daily analytics refreshes. Database: Normalized 55-table schema covering users, resumes, applications, and logs. 5.

Current stack: • Laravel backend • React frontend • MySQL database • Redis caching • Nginx web server The application is already running in production and performing well, but the infrastructure needs to be redesigned to support traffic growth and high availability. Scope of work: • design and implementation of scalable AWS infrastructure • Application Load Balancer setup • Auto Scaling Groups for application servers • migration of database layer to Amazon RDS • Redis cluster configuration using ElastiCache • migration of file storage to Amazon S3 • CDN setup using CloudFront • in...

...React and Vue, so deep, recent experience with either (or both) is essential. Server-side, our critical services are written in Python and Java; you should feel comfortable switching between them as new features demand. Data currently lives in MySQL, and you’ll be expected to design tables, write optimized queries, and wire everything up through well-structured RESTful APIs. Familiarity with Redis or MongoDB is a welcome bonus because we intend to introduce additional caching and document-store layers later this year. Day to day you’ll: • Ship new user-facing modules and internal tools. • Extend existing Python/Java micro-services, keeping performance in mind. • Review and improve system architecture for scalability. • Own deployments...
