Proficient in Agentic and GENAI concepts
Generative AI (GenAI) core concepts
Foundation models (FMs): Large pre-trained models (LLMs, multimodal) that generalize across tasks.
Prompting & instructions:
How inputs steer outputs; includes system vs user intent, constraints, and tone.
The model's short-term "working memory limit for text/images in a single run
Retrieval-Augmented Generation (RAG): Pulling relevant knowledge from external sources (docs/search/vector DB) to ground answers.
Embeddings & vector search:
Turning content into vectors to enable semantic retrieval and similarity matching.
Fine-tuning vs adapters (e.g.
, LoRA):
Updating model behavior with task data; tradeoff between control, cost, and maintenance.
Letting the model invoke calculators, APIs, databases, workflows, and other systems.
JSON/schema-constrained outputs for reliability and system integration.
Evaluation (evals): Measuring quality with tests (accuracy, faithfulness, toxicity, latency, cost).
Confident-sounding incorrect outputs; mitigated via RAG, constraints, verification, and UX patterns.
Safety & governance:
Policy controls, red-teaming, data handling, and auditability.
A model that can plan, act, and iterate toward a goal (not just answer once).
From "suggest-only to "execute with approvals to "fully automated (rare in enterprise).
Planning & decomposition:
Breaking goals into steps/subtasks; selecting strategies and sequencing actions.
Tool use & action execution:
Calling tools/APIs to change state (create tickets, deploy, update records).
Persisted preferences/knowledge (user, task, org) vs ephemeral conversation context.
State & workspace:
Tracking intermediate artifacts (tasks, assumptions, files, run logs).
Self-checking, critique, or second-pass validation to reduce errors.
Multi-agent patterns: Specialized agents (e.g., researcher, coder, reviewer) coordinating with handoffs.
Human-in-the-loop (HITL): Approval gates, review queues, and escalation when confidence is low.
Policy checks, allowlists/denylists for tools, spend limits, and sensitive-data filters.
Traces, tool-call logs, failure modes, and metrics (success rate, MTTR, cost per task).
Design, develop, test, and deploy scalable RESTful APIs using Python and the FastAPI framework.
Collaborate with frontend teams to build and integrate APIs with web applications.
CI/CD Ownership:Build and maintain CI/CD pipelines using GitHub Actions and Azure DevOps to ensure rapid and reliable delivery of code to production.
Implement security best practices across web applications and APIs, including OAuth2, JWT, and secure coding standards.
Code Quality & Testing:
Write clean, modular code with strong emphasis on unit testing, integration testing, and code reviews.
