    With 13 years in full-stack engineering and system design, 6 years in AWS Solutions Architecture, and 10 years in leadership, I have built dozens of technically successful apps, often from scratch, alone or in teams. My experience spans a wide range of development, from fast MVPs to giant modular monoliths and event-driven microservices. I have successfully transformed legacy systems into modern, scalable, and robust systems, developed high-load solutions from scratch, and created custom frameworks, front-end and back-end component libraries, and SDKs. I have mentored and led teams to success. By making good technology choices and establishing proper processes, I have improved the performance of entire projects by up to 300%. I am passionate about my work and will genuinely love your projects as my own, with great attention to detail and focus on the goals of your business. COMPANIES TRUST Workato.com, All4Labels.com, Chingari.io, Shastic.com, Zirtue.com PEOPLE SAY “His expertise in complex system design and AWS solutions was crucial in addressing multiple use cases. Alexandr's ability to deliver scalable, secure, and efficient systems makes him an invaluable asset. Highly recommended.” — Juergen Koehler | All4Labels “When I think of Aleksandr, one word comes into my head - overqualified. And I mean that in a good way when that's not a problem but a solution.” — Dmitry Matora | SalesLyft, All4Labels “I had the pleasure of working with Aleksandr on an exciting [open source] project and he exceeded all my expectations” — William Reiske | BlueHive, Medical Informatics Engineering I BELIEVE - Only architects who code and developers who architect can truly excel in either field. - Architecture is not about building software in the most complex and sophisticated way. It is about making the correct choices in the given context. - Often, communication and teamwork are more important than technical skills. - Leading the software project is more than knowing where to go and how to get there. - Competence can be replaced with AI. Today, you have to bring more than that. - Remote work can be more efficient than on-site. I DON'T COMPROMISE ON: - Delivering results, even on tasks others find impossible. - Clear communication and avoiding drama. - Upholding honesty and loyalty. - Innovating effective solutions, even in uncharted territory. - Continuous learning KEY SKILLS Languages: - JavaScript & TypeScript (~95%) - Python (~4%), Rust (~1%), Lua (~1%) UI: - HTML, CSS, Tailwind, Bootstrap, MaterialUI, ShadCN Frontend: - React, ZuStand, Redux Toolkit, ReactQuery, Tanstack Router Backend & Full-Stack: - NextJS, tRPC, NestJS, Express, Fastify, Feathers API & Protocols: - ReST, GraphQL, tRPC, gRPC, WebSockets Validation and Serialization: - class-validator, class-transformer, Zod, TypeBox, JSON Schema DB: - Postgres, MySQL, MongoDB, Redis, DynamoDB, Cassandra, ElasticSearch ORM, ODM, etc.: - Sequelize, TypeORM, Knex, Drizzle, Prisma, Mongoose AWS (real commercial hands-on experience): - IAM, Route53, CloudFront, Global Accelerator, API Gateway, S3, FSx, EFS, ECS, EKS, EC2, ECR, ELB, Auto Scaling, Lambda, StepFunctions, Batch, SageMaker, Ground Truth, Recognition, Transcribe, Comprehend, Textract, Glue, Athena, OpenSearch, LakeFormation, Kinesis, MSK (Kafka), DynamoDB, RDS (Postgres, MySQL, Aurora, Proxy) ElastiCache, DocumentDB, VPC, VPC Peering, VPN, Transit Gateway, SNS, SQS, Amazon MQ, EventBridge, Cloud Formation, CDK, CodeBuild, CodePipeline, CodeStar, X-Ray, CloudWatch, CloudTrail, WAF, Shield, Secrets Manager, Systems Manager IaC: - Terraform, CDK, CloudFormation Build and monorepo tools: - Nx, Turborepo, Docker, Webpack, EsBuild, EsLint, Vite Other: - Unix, Bash, Kubernetes, GoF, SOLID, GRASP, DDD, Event Sourcing, CQRS, MVC, Hexagonal, n-Tier, Clean, EDA, SOA, Saga, TDD, BDD, C4(+1), UML, Flow Chart, MBPN, etc., etc.
